Learn Java Programming - InputStreamReader class Tutorial
 
10:09
The InputStreamReader class can serve multiple purposes, but primarily it is used to convert byte streams to character streams. This tutorial builds on concepts from my Introduction to I/O Tutorial, I highly recommend watching it first. InputStreamReader has several overloaded constructors with each on taking an InputStream (like System.in, or FileInputStream) as the first parameter. This tutorial will utilize the constructor that only takes a single parameter. The InputStreamReader class has a method called close() that will close the stream and releases any system resources associated with it. The close() method should always be called once you are done with the input stream. In Java 7 a new feature called try-with-resources was introduced. Specifically a resource is an object that must be closed after the program is finished with it. The try-with-resources statement ensures that each resource is closed at the end of the statement. How do we know if a class is a resource? Simple, if it implements java.lang.AutoCloseable, the class can be considered a resource. I'll demonstrate how this feature works.

Learn Java Programming - OutputStreamWriter to the console Tutorial
 
05:53
The OutputStreamWriter class can serve multiple purposes, but primarily it is used to convert character streams to byte streams. This tutorial is practically the exact opposite of my InputStreamReader Tutorial, I highly recommend watching it first. OutputStreamWriter has several overloaded constructors with each taking an OutputStream (like System.out, or FileOutputStream) as the first parameter. This tutorial will utilize the constructor that only takes a single parameter. The OutputStreamWriter class implements AutoClosable so we can use the try-with-resources type exception handling. There are only four public methods in the OutputStreamWriter class: close(), flush(), getEncoding(), and write(). The close() method will be handled by our try-with-resources syntax, we'll ignore the flush() and getEncoding() for now, and the write() method has three overloaded versions.

Learn Java Programming - FileOutputStream Tutorial
 
11:17
All of my I/O tutorials up until now have been dealing with Character Streams. In this tutorial I will begin to introduce you to writing Byte data to a file. The primary purpose of the FileOutputStream class is to write an output stream to a file. This tutorial will demonstrate the write(int b) method to create a BMP image file from scratch. By the end of this tutorial you will have created an 8x8 pixel striped-color bitmap image file. The FileOutputStream class implements AutoClosable so we can use the try-with-resources type exception handling. I will demonstrate the other overloaded versions of the write() method in my FileInputStream tutorial.

Loading Resources In Java Using Eclipes IDE
 
04:02
There are many questions posted on Experts Exchange by people starting out in Java programming, who are using an IDE, most often Eclipse and sometimes NetBeans that center around their application not being able to find a file. This is quite often an image they want to use in their application. This often happens when they create an 'executable jar'. An executable jar is an application that can be made to run in a windowing environment by double-clicking a shortcut icon, much the same as one can get a native application to run. The ultimate cause of the problem is the failure to understand the concept of the 'current directory' or the 'working directory'. Wikipedia tells us: "In computing, the working directory of a process is a directory of a hierarchical file system, if any,[1] dynamically associated with each process. When the process refers to a file using a simple file name or relative path (as opposed to a file designated by a full path from a root directory), the reference is interpreted relative to the current working directory of the process. So for example a process with working directory /rabbit-hats that asks to create the file foo.txt will end up creating the file /rabbit-hats/foo.txt." ( http://en.wikipedia.org/wiki/Working_directory ) When developers starting out want to display, say my-image.png in the program, they often refer to this only by the path "my-image.png", having copied this into the project. This will work fine when the application is run through the IDE, but when, like all good java applications, it is made into an executable jar and the resulting icon is double-clicked, the application fails. Worse still, since Windows associates the open action of a .jar file with javaw.exe, which is designed to run without a console window, apparently nothing at all happens and the reason the application fails is a mystery. The application is not 'relocatable'. The solution to this problem is to package the resources together with the class files in the application jar. One of the best ways to do this is to create a 'resources' folder at the package root and to place any needed resources in there. An video example of doing that in the Eclipse IDE can be seen here.

Learn Java Programming - FileInputStream Tutorial
 
10:23
The primary purpose of the FileInputStream class is to read an input stream from a file. This tutorial will directly compliment my FileOutputStream Tutorial as I will take the BMP image we built in that tutorial, read it in, manipulate it, and write it back out. The FileInputStream class implements AutoClosable so we can use the try-with-resources type exception handling.

Learn Java Programming - BufferedReader Tutorial
 
08:58
The BufferedReader class is used to read text from a character stream. This tutorial builds on concepts from both my InputStreamReader Tutorial and my FileReader Tutorial, I highly recommend watching them first. This tutorial will demonstrate reading text from an input stream from the keyboard and will also demonstrate reading an input stream from a text file. The BufferedReader class has the same read() method that both InputStreamReader and FileReader use to read a single byte at a time. The BufferedReader class introduces a method named readLine() which will read an entire line of text which is a huge improvement. The BufferedReader class implements AutoClosable so we can use the try-with-resources type exception handling.

What is RT.jar ? | rt.jar | Importance | Part 5
 
06:18
we will discuss rt.jar and its usage. For a beginner, this will be one of the question which they might have. For an expert even though this is well known jar file in Java, but very few people will know what it is and why it is so important. As most of you aware, rt.jar stands for Run Time JAR and contains bootstrap classes, and the people who knows JVM architecture, Bootstrap class loader loads all JAVA API core classes(or Bootstrap classes ) from Bootstrap class path, ultimately which is nothing but rt.jar loaded by Bootstrap class loader. You must include rt.jar in your classpath, otherwise you don't have access to core classes e.g. java.lang.String, java.lang.Thread, java.util.ArrayList or java.io.InputStream and all other classes from Java API. along with the burden with 18000+ class files in a single jar file. Even if you want to go with very basic program to be develop and execute , all bootstrap classes or core API classes will be loaded even though really we don't require for a very basic application. Due to this it leads to performance issues. As the new versions are releasing, rt.jar and other jar files are growing very huge. In order to avoid that, Java 9 is planned well to improve the performance by removing rt.jar and tools.jar . As a very high level: "The core API classes and resource files previously stored in rt.jar, tools.jar, dt.jar, and various other internal jar files, now these will be stored in a more efficient format in implementation-specific and private files in the lib directory. -~-~~-~~~-~~-~- Please watch: "What is JShell ? | Practical explanation of JShell | Java 9 feature JShell | JShell | REPL" https://www.youtube.com/watch?v=T-e1EnKgWq0 -~-~~-~~~-~~-~-

Android Developing Applications Tutorial 42 Using BitmapFactory and InputStream to set Bitmap
 
06:40
Android is a mobile operating system currently developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. And as we said before, Android offers a unified approach to application development for mobile devices. Android is an open-source operating system named Android. Google has made the code for all the low-level "stuff" as well as the needed middleware to power and use an electronic device, and gave Android freely to anyone who wants to write code and build the operating system from it. There is even a full application framework included, so third-party apps can be built and installed, then made available for the user to run as they like. Android is an open source and Linux-based Operating System for mobile devices such as smartphones and tablet computers. Android was developed by the Open Handset Alliance, led by Google, and other companies. Android offers a unified approach to application development for mobile devices which means developers need to develop only for Android, and their applications should be able to run on different devices powered by Android. 1 - Download and Install the Java JDK 2 - Installing Eclipse and Setting up the ADT 3 - Installing Android SDK and Set up Emulator 4 - Setting up an Android Project 5 - Overview of Project and Adding Folders 6 - Introduction to Layouts in XML 7 - Creating A Button in XML and Adding an ID 8 - Setting up Variables and Referencing XML ids 9 - Set up a Button with OnClickListener 10 - Using setText method for our button 11 - Adding Resources and Setting Background 12 - Setting up an Activity and Using SetContentView 13 - Introduction to the Android Manifest 14 - The Framework of a Thread 15 - How to Start a New Activity via Intent 16 - Activity Life Cycle 17 - Adding Music with MediaPlayer 18 - Create a List Menu from the ListActivity class 19 - Setting up an ArrayAdapter 20 - Starting an Activity with a Class Object 21 - Finishing ListActivity 22 - XML Introducting the EditText 23 - XML ToggleButton, WeightSum, and Layout Weight 24 - XML Padding and Setting Toggle to On 25 - Quick Review by setting up a new Activity 26 - If Toggle Button is checked 27 - Set the Input Type of an EditText 28 - Comparing Strings with else if 29 - Set Gravity within Java 30 - Setting Color of a TextView in Java 31 - Where's the Fridge, that's Random 32 - Switch and Case 33 - Creating a Method 34 - Implementing Classes for Better Programming 35 - XML ScrollView and AnalogClock 36 - Setting up An Email Activity 37 - PutExtra method for an Email Intent 38 - XML ImageView for Camera Application 39 - Starting an Activity for a Result 40 - Getting Data from a different Activity 41 - Finish Camera and Wallpaper App 42 - Using BitmapFactory and InputStream to set Bitmap 43 - Set Fixed Screen Orientation 44 - XML Relative Layout 45 - RadioButtons in a RadioGroup 46 - Set the Radio to the OnCheckedChangeListener Station 47 - Passing a String between Activities 48 - Recieving Bread String from Activity 49 - StartActivityForResult setup 50 - setResult for the Start Activity For Result 51 - Setting up a Menu with MenuInflater 52 - Making MenuItems do something 53 - Text Activity with Theme 54 - Setting up Preferences 55 - Setting up a String array resource 56 - Creating a PreferenceActivity 57 - Accessing Preferences from an Activity 58 - More with Preferences 59 - Altered Landscape Layout 60 - Creating Custom Buttons 61 - Full Screen Activities 62 - Custom Animation Class 63 - Using a Constructor to pass Context 64 - Drawing Bitmaps to Canvas View 65 - Animating a Bitmap 66 - Using the Asset Folder for Typeface 67 - Setting up a SurfaceView class 68 - Setting up Animation Thread 69 - Locking and Unlocking a Canvas 70 - Establishing a Better Animation Thread 71 - Setting up the OnTouch Method 72 - Defining a Class within a Class 73 - Graphics Trick 74 - MotionEvents and Motion Actions 75 - Game Programming concept 76 - Cleaning up some Errors 77 - Sleeping to Achieve desired FPS 78 - WakeLock to keep you app from sleeping 79 - SoundPool helps with explosions 80 - Using the OnLongClick method 81 - SlidingDrawer Example 82 - Introduction to the FrameLayout 83 - Methods of the SlidingDrawer 84 - Tabs setup with TabHost 85 - Setting up the TabHost in Java 86 - Creating Tabs in Java 87 - Getting the Time from the System 88 - Formatting and using the Modulus 89 - Create a Browser with WebView 90 - WebView navigation methods 91 - Set WebView Client for a Brower app 92 - WebView Settings 93 - Hiding the Keyboard 94 - ViewFlipper Example 95 - Saving Data with SharedPreferences 96 - SharedPreferences Editor 97 - Loading SharedPreferences Data 98 - File Output Stream for Internal Storage 99 - Writing Data to File Output Stream 100 - File Input Stream

Java Input/Output Question Answer Quiz
 
02:47
Java Input/Output Question Answer Quiz The java.io package contains nearly every class you might ever need to perform input and output (I/O) in Java. All these streams represent an input source and an output destination. The stream in the java.io package supports many data such as primitives, object, localized characters, etc. A stream can be defined as a sequence of data. There are two kinds of Streams − InPutStream − The InputStream is used to read data from a source. OutPutStream − The OutputStream is used for writing data to a destination. Streams Java provides strong but flexible support for I/O related to files and networks but this tutorial covers very basic functionality related to streams and I/O. We will see the most commonly used examples one by one − Byte Streams Java byte streams are used to perform input and output of 8-bit bytes. Though there are many classes related to byte streams but the most frequently used classes are, FileInputStream and FileOutputStream. Character Streams Java Byte streams are used to perform input and output of 8-bit bytes, whereas Java Character streams are used to perform input and output for 16-bit unicode. Though there are many classes related to character streams but the most frequently used classes are, FileReader and FileWriter. Standard Streams All the programming languages provide support for standard I/O where the user's program can take input from a keyboard and then produce an output on the computer screen. If you are aware of C or C++ programming languages, then you must be aware of three standard devices STDIN, STDOUT and STDERR. Similarly, Java provides the following three standard streams − Standard Input − This is used to feed the data to user's program and usually a keyboard is used as standard input stream and represented as System.in. Standard Output − This is used to output the data produced by the user's program and usually a computer screen is used for standard output stream and represented as System.out. Standard Error − This is used to output the error data produced by the user's program and usually a computer screen is used for standard error stream and represented as System.err. Reading and Writing Files As described earlier, a stream can be defined as a sequence of data. The InputStream is used to read data from a source and the OutputStream is used for writing data to a destination. FileOutputStream FileOutputStream is used to create a file and write data into it. The stream would create a file, if it doesn't already exist, before opening it for output. Here are two constructors which can be used to create a FileOutputStream object. Following constructor takes a file name as a string to create an input stream object to write the file − OutputStream f = new FileOutputStream("C:/java/hello") Following constructor takes a file object to create an output stream object to write the file. First, we create a file object using File() method as follows − File f = new File("C:/java/hello"); OutputStream f = new FileOutputStream(f); Once you have OutputStream object in hand, then there is a list of helper methods, which can be used to write to stream or to do other operations on the stream. Sr.No. Method & Description 1 public void close() throws IOException{} This method closes the file output stream. Releases any system resources associated with the file. Throws an IOException. 2 protected void finalize()throws IOException {} This method cleans up the connection to the file. Ensures that the close method of this file output stream is called when there are no more references to this stream. Throws an IOException. 3 public void write(int w)throws IOException{} This methods writes the specified byte to the output stream. 4 public void write(byte[] w) Writes w.length bytes from the mentioned byte array to the OutputStream. There are other important output streams available, for more detail you can refer to the following links − ByteArrayOutputStream DataOutputStream -~-~~-~~~-~~-~- interview question and answers https://www.youtube.com/watch?v=8dhBq_elHg8 interview question and answers https://www.youtube.com/watch?v=pC1mVWj9iq8&t=9s interview question and answers https://www.youtube.com/watch?v=3WuliE8Jmt0&t=6s interview question and answers https://www.youtube.com/channel/UCyNJURC5bvqIQ9vO9PBrYrA/videos?view_as=subscriber interview question and answers https://www.youtube.com/watch?v=6Z5OzXzQqUM&t=5s interview question and answers https://www.youtube.com/watch?v=Max8PhFkWtg&t=4s interview question and answers https://www.youtube.com/watch?v=Xd7Yk4vEpuo&t=7s interview question and answers https://www.youtube.com/watch?v=yc3V4pXPEpk Please watch: "Html interview questions and answers for freshers" https://www.youtube.com/watch?v=8dhBq_elHg8 -~-~~-~~~-~~-~-

Android is a mobile operating system currently developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. And as we said before, Android offers a unified approach to application development for mobile devices. Android is an open-source operating system named Android. Google has made the code for all the low-level "stuff" as well as the needed middleware to power and use an electronic device, and gave Android freely to anyone who wants to write code and build the operating system from it. There is even a full application framework included, so third-party apps can be built and installed, then made available for the user to run as they like. Android is an open source and Linux-based Operating System for mobile devices such as smartphones and tablet computers. Android was developed by the Open Handset Alliance, led by Google, and other companies.

Java Programming for Mobile Developers Part 6
 
06:37
Java Programming for Mobile Developers Part 6 ! The use of several of the Java I/O classes may be required to successfully receive input that is typed by the user. The java.io package contains most, if not all, of the classes you will need to use. The java.util package also contains some classes that are useful for input and output. Don't worry, you won't need to use all 50+ classes. But, you will need to learn about and use at least a couple of them. Either use the fully qualified name shown or import the specified package to use either of these classes. java.io.InputStream - stores information about the connection between an input device and the computer or program. java.util.Scanner - used to read the input available from an InputStream object. The Scanner class has a method called nextLine that returns a line of text as typed by the user. There are two available constructors for creating a Scanner object. For console input, we will use the one that requires only one argument, an instance of an InputStream object. We will use the System.in object as our InputStream object and then use that object to create an instance of the Scanner class. Steps for console based user input: Use the System.in object to create a Scanner object. Display a prompt to the user for the desired data. Use the Scanner object to read a line of text from the user. Do something interesting with the input received from the user. Would you like to see some code? I thought so. Here it is: 1. Create a Scanner using the InputStream available. Scanner scanner = new Scanner( System.in ); 2. Don't forget to prompt the user System.out.print( "Type some data for the program: " ); 3. Use the Scanner to read a line of text from the user. String input = scanner.nextLine(); 4. Now, you can do anything with the input string that you need to. Like, output it to the user. System.out.println( "input = " + input ); Resources : http://www.oracle.com/technetwork/topics/newtojava/overview/index.html https://www.udacity.com/course/intro-to-java-programming--cs046 http://eclipse.org/downloads/ https://developer.android.com/training/index.html https://developer.android.com/sdk/index.html https://www.udemy.com/java-essentials-for-android/ http://www.javaworld.com/article/2093747/java-ios-developer/12-predictions-for-the-future-of-programming.html http://www.javaworld.com/ http://www.amazon.com/Java-Programming-Android-Developers-Dummies/dp/1118504380 https://www.java.com/en/about/ Disclaimer : This video does not represent "Java Programming for Mobile Developers" officially.
