| Welcome to the spoken tutorial on '''HelloWorld in Java on 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 tutorial 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 project select '''Java Project ''' and click '''Next.'''

|-
| 01:26
| In the project name ,Type '''DemoProject ''' (please note that their 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'''.
This opens a '''New Java Class Portlet'''

|-
| 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 '''Demo program.Java''',
|-
|02:27
|This is because every class in Java has to be in its own file. Hence the class Demo Program can exist only in the file ''' Demo program. Java'''

|-
|02:40
| We can see that there is very little space for the editor and the view looks blurred . Let us minimise 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 comments also.
|-
|03:22
|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, '''HelloWorld'''

|-
|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'''.'''Run''' the code

|-
|04:19
|As we can see on the output console, the message '''HelloWorld''' has been printed.

|-
|04:24
|Now let us change the ''' World''' to '''Java'''

|-
|04:30
|Save it with '''Ctrl + S''' and '''Run''' it.

|-
|04:41
|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 its 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 '''HelloWorld''' 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 'HelloWorld' 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.
