* Ubuntu version 11.10 and
* Java Development Environment JDK 1.6

|-

Pre-requisites
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| To follow this tutorial you must be connected to the internet.

You must have Synaptic Package Manager installed on your system.

You must also have knowledge of using '''Terminal''', '''Text Editor''' and '''Synaptic Package Manager''' in '''Linux'''.

If not, please see the Spoken Tutorial on Linux, available at spoken-tutorial.org.

| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Slide 4
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| To run a java program we need to install the '''JDK''', the '''Java Development Kit.'''

To learn more about''' JDK''' you could visit the following link:

[http://docs.oracle.com/javase/6/docs/index.html http://docs.oracle.com/javase/6/docs/index.html]

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Slide 5
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| Now we will install the '''JDK''' using '''Synaptic Package Manager.'''

For this, you need to have root permissions.

You also need to know how to choose a repository.

These are explained in the pre-requisite tutorial on Linux mentioned earlier.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Switch to Desktop

Click on '''DashHome'''

Type''' Synaptic '''in the''' search box.'''
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| Now, on the left corner of your '''Desktop''', you will find the '''Taskbar'''.

At the top you will find '''DashHome'''.

Click on '''DashHome.'''

In the search bar type '''Synaptic.'''

You will find '''Synaptic Package Manager '''here'''.'''

'''Click '''on '''Synaptic Package Manager.'''

You will be asked to type your password for '''Authentication'''.

So type your '''password''' and '''click '''on '''Authenticate'''.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Type '''jdk '''in the quick search box.
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| This opens the '''Synaptic Package Manager.'''

Now In the '''Quick Filter '''box type '''jdk'''.

We see a '''package''' named '''openjdk-6-jdk.'''

'''Right click '''on it and''' click '''on '''Mark for Installation'''.

Then click on '''Apply'''.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Right click on '''openjdk-6-jdk'''.

Click '''Mark for Installation'''

Click on '''Apply'''
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"|

You will be asked to confirm the list of marked changes.

So '''click''' on '''To be Installed '''and then '''click '''on '''Apply'''.

The installation will take a few seconds.

Now, we see that the option '''openjdk-6-jdk''' is in green colour.

Thus our installation is complete.

Now, let us verify the installation, For this open the terminal by presing ''Ctrl, Alt and T keys simultaneously

I already opened have my '''Terminal''' opened here.

At the command prompt type '''java''' space hyphen '''version''' and press '''Enter'''.

We see that the '''version number''' of the '''jdk''' has been displayed.

Depending on the version that you used your '''version number''' could be different.

So, we have successfully installed the '''jdk'''.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Open the code in''' TextEditor.'''
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| Now, let us run a simple Java program and see if it works.

I already have the following code saved in the file name '''TestProgram dot java'''.

Let me compile and run this code.

This code simply displays '''We have successfully run a Java Program''' on the '''Terminal'''.

So let us go back to the''' Terminal'''.

Remember that I have saved the file '''TestProgram''' ''dot'' '''java''' in the '''Home''' '''directory'''.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"|
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| And currently I am in the '''Home Directory.'''

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"|
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:0.035cm solid #000000;padding:0.097cm;"| At the command prompt type '''javac''' ''space''' ''TestProgram''' ''dot'' '''java.'''

This is to compile the code.

Press '''Enter.'''

Now, let me run the code.

So type '''java''' space '''TestProgram ''' and press '''Enter'''.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"|

Thus, our installation has been perfect.

Now, let us go back to the slides.

|-
| style="border-top:none;border-bottom:0.035cm solid #000000;border-left:0.035cm solid #000000;border-right:none;padding:0.097cm;"| Slide 6

1. Java is simple.

2. Java is object oriented.

3. It is platform independent.

4. It is safe.

5. Java has high performance.

6. Java is multi – threaded.

-'''JSP, or Java Server Pages: '''It is based on a code with normal HTML tags.

JSP helps in creating dynamic web pages. 

-'''Java Applets''': It is used to provide interactive features to web applications.

-'''J2EE or Java Enterprise Edition: '''Companies use J2EE.

It is useful to transfer XML structured documents.

-'''JavaBeans''': JavaBeans is a reusable software component.

It can be used to build new and advanced applications.

-'''Mobile Java''': It is used for various entertainment devices, such as mobile phone.
