Time Narration
00:01 Welcome to the spoken tutorial on HelloWorld in Java using Eclipse.
00:06 In this tutorial, we are going to learn how to write a simple Hello World program in Java using Eclipse.
00:13 For this tutorial, we are using Eclipse 3.7.0 and Ubuntu 11.10.
00:20 To follow this tutorial, you must have Eclipse installed on your system.
00:25 And you must know how to create, save and run a file in Eclipse.
00:30 If not, for relevant tutorials, please visit our website as shown.
00:36 Here is a line of java code that prints the message Hello World.
00:44 Now, let us try it on Eclipse.
00:46 Press Alt, F2 and in the dialog box, type eclipse and hit Enter.
00:56 Click OK at the workspace and here we have the 'Eclipse IDE'.
01:09 Now, let us add a new project.
01:12 Click File, New and select Project .
01:19 In the list of projects, select Java Project and click Next.
01:26 In the project name, type DemoProject (please note that there is no space between Demo and Project, D & P are in capital letters).
01:40 Click Finish at the bottom right corner of the wizards.
01:46 DemoProject has been created.
01:49 Now, let us add a new class to the project.
01:52 Right click on the Project, New, select Class.
01:59 In the class name, type DemoProgram and in the method stubs select one that says public static void main.
02:13 Click Finish at the bottom right corner of the wizard.
02:20 We can see that the DemoProject has the source directory and a file called DemoProgram.Java.
02:27 This is because every class in Java has to be in its own file. Hence the class 'DemoProgram' can exist only in the file Demoprogram.java.
02:40 We can see that there is very little space for the editor and the view looks cluttered. Let us minimize the other portlets and here we have the editor .
02:55 Notice that this line begins with two slashes which means this line is the comment and has nothing to do with our code.
03:05 Let us remove this line. Similarly every thing that is in between slash Astrix (/*) and Astrix slash (*/) is also a comment.
03:17 So, let us remove this comment also.
03:22 And here we have the bare bones of the code.
03:27 Now let us add the print statement, System.
03:35 Notice that eclipse gives a list of all the possible completions.
03:38 For now, we are going to type the command manually;
03:43 out.println. In brackets in quotes type: Hello World
03:56 In java, every statement has to end with a semicolon.
03:59 So, let us add a semicolon.
04:03 Here, these are complete HelloWorld program in Java.
04:06 Press Ctrl + S to save.
04:11 Right click Run as, Java Application to run the code.
04:19 As we can see on the output console, the message Hello World has been printed.
04:24 Now, let us change the "World" to "Java".
04:30 Save it with Ctrl + S and run it.
04:40 As we can see, the message that is printed now is Hello Java.
04:45 Now let us understand what each part of code does?
04:48 The first line indicates that the class name is 'DemoProgram' and it's a Public class.
04:55 The second line indicates that this is the main method. In other words the method from which execution starts with java.
05:04 As we know, this is a print statement.
05:07 And here is how we write a Hello World program in Java.
05:14 This brings us to the end of the tutorial.
05:17 In this tutorial, we have learnt how to write a Hello World program in java and also what each part of code does in java code.
05:27 As an assignment for this tutorial-
05:29 create a java class by the name Greet, it should bring "Program Successful" when executed.
05:37 To know more about the spoken-tutorial project.
05:39 Watch the video available at the following link.[1]
05:42 It summarizes the Spoken Tutorial project.
05:45 If you do not have good bandwidth, you can download and watch it.
