Slide 1 Welcome	Welcome to the spoken tutorial on HelloWorld in Java using Eclipse.
Slide 2 Learning Outcomes	In this tutorial, we are going to learn how to write a simple helloWorld program in Java using Eclipse.
Slide 3 Tools Used	For this tutorial we are using Eclipse 3.7.0 and Ubuntu 11.10
Slide 4 Pre-requisites	To follow this tutorial you must have Eclipse installed on your system. and You must know how to create, save and run a file on Eclipse. If not, for relevant tutorial please visit our website as shown.
Slide 5 "HelloWorld" System.out.println("Hello World");	Here is a line java code that prints the message Hello World Now Let us try it on Eclipse.
Minimize slides and launch Eclipse Alt + F2 > eclipse	Press Alt and F2 and in the dialog box type eclipse and hit enter. Click Ok at the Workspace And here we have the Eclipse IDE.
Click on File > New > Project	Now let us add a new project click File New and select Project
Select Java Project. Click Next	In the list of project Select Java Project and clickNext.
In the project name Type DemoProject Click Finish	In the project name Type DemoProject Please note that their is no space between Demo and Project 'D and P are in capital letters. Click Finish at the bottom right corner of the wizards. The DemoProject has been created
Point to the Project Explorer portlet on the left.	Now let us add a new class to the project. Right click on the Project New select Class.
Point to the New Java Class portlet Point to the list of method stubs Click Finish	In the class name type DemoProgram and in the method stubs select one that says Public, Static,Void main. Click Finish at the bottom right corner of the wizard.
Point to the src directory in Project Explorer Portlet	We can see that the DemoProject has the source directory and the Demo program.Java, This is because every class in Java has to be in its own file. Hence the class Demo Program can exit only in the file Demo program. Java
Point to the “code editor” Type in Eclipse After the line “public static void main” System System.out.println( System.out.println(“) System.out.println(“HelloWorld”); Press Ctrl + S	We can see that their is very little space for editor and the view looks blurred er Let us minimise thr other portiere and here we have the editor . Notice that this line begins with two slashes which means this line is the comment and has nothing to do with our code. Let us remove this line. Similarly every thing that is in between slash, Astrix and Mastic slash is also accompanied. We will learn about all this once we get some output. Let us type the print statement. As we can see, Eclipse suggests various possibilities as we type a command. Let us complete the command. Eclipse also completes the parentheses by automatically adding the closing parentheses. Let us add the statement that we want to print. The message has to be included in double quotes. As we can see, Eclipse also completes the quotes by adding the closing quote. There is a semicolon at the end of the statement. Every statement in Java must end with a semicolon. Now our program is complete. Save the file by pressing Ctrl + S simultaneously..
Click on the code editor	Now let us compile and execute the program. Right click on the source code, go to Run as option, and then click java application.
Point to output console at the botom of the code editor	The output message HelloWorld is displayed in the console window. So we have written a simple java program and executed it successfully.
Replace HelloWorld with Hello Java and run the code.	Now, let us change the code to print a different message. Replace HelloWorld with Hello Java and run the code. As we can see, the message printed now is Hello Java
Point to the line public class DemoProgram Point to the line public static void... Point to the opening and closing braces Select from opening to closing braces of the class. Select from opening to closing braces of the main method.	Now let us understand the program piece by piece. The line class DemoProgram indicates that the name of our class is DemoProgram. This is required since every source file in java is a class. The next line defines the main method. It is the code inside main method that will be executed when you run a java program. The opening and closing braces suggest which part of code goes under which name. This block of code belongs to the DemoProgram class. This block of code belongs to the main method.
Minimize the Eclipse window and switch to slides. Slide 6 Summary	We have come to the end of this tutorial. In this tutorial we have learnt how to write 'HelloWorld' program using Eclipse. We have also understood what each piece of the program does.
Slide 7Assignment	Create a java class by the name Greet that prints Program Successful when executed.
