Time	Narration
00:01	Welcome to the Spoken Tutorial on Getting started with Java Installation.
00:07	In this tutorial, we will learn:
00:09	To install the JDK using Synaptic Package Manager.
00:13	Why Java? Types and applications of Java.
00:17	Here we are using:
00:19	Ubuntu version 11.10 and
00:21	Java Development Environment JDK 1.6 .
00:26	To follow this tutorial, you must be connected to the internet.
00:31	You must have Synaptic Package Manager installed on your system.
00:35	You must also have knowledge of using Terminal, Text Editor and Synaptic Package Manager in Linux.
00:43	If not, please see the Spoken Tutorial on Linux, available at spoken-tutorial.org.
00:51	To run a java program we need to install the JDK, the Java Development Kit.
00:57	To learn more about JDK, you could visit the following link:
01:02	Now we will install the JDK using Synaptic Package Manager.
01:07	For this, you need to have root permissions.
01:10	You also need to know how to choose a repository.
01:14	These are explained in the prerequisite tutorial on Linux, mentioned earlier.
01:19	Now, on the left corner of your Desktop, you will find the Taskbar.
01:25	At the top you will find DashHome.
01:28	Click on DashHome.
01:31	In the search bar, type Synaptic.
01:35	You will find Synaptic Package Manager here.
01:38	Click on Synaptic Package Manager.
01:42	You will be asked to type your password for Authentication.
01:47	So, type your password and click on Authenticate.
01:56	This opens the Synaptic Package Manager.
02:03	Now In the Quick Filter box, type jdk.
02:08	We see a package named openjdk-6-jdk.
02:13	Right click on it and click on Mark for Installation.
02:17	Then click on Apply.
02:20	You will be asked to confirm the list of marked changes.
02:24	So click on To be Installed and then click on Apply.
02:30	The installation will take a few seconds.
02:38	Now we see that the option openjdk-6-jdk is in green colour.
02:48	Thus our installation is complete.
02:52	Now, let us verify the installation. For this, open the terminal by pressing Ctrl, Alt and T keys simultaneously.
03:03	I already have my terminal opened here.
03:06	At the command prompt, type: java space hyphen version and press Enter.
03:15	We see that the version number of the 'jdk has been displayed.
03:20	Depending on the distribution that you used your version number could be different.
03:26	So, we have successfully installed the jdk.
03:30	Now, let us run a simple Java program and see if it works.
03:35	I already have the following code, saved in the file name TestProgram dot java.
03:42	Now, let me compile and run this code.
03:45	This code simply displays We have successfully run a Java Program on the Terminal.
03:53	So, let us go back to the Terminal.
03:57	Remember that I have saved the file TestProgram dot java in the Home directory.
04:03	And currently I am in the Home Directory.
04:07	So, at the command prompt, type: javac space TestProgram dot java.
04:19	This is to compile the code.
04:21	Press Enter.
04:25	Now, let me run the code.
04:27	So, type: java space TestProgram and press Enter.
04:35	We get the output as We have successfully run a java program.
04:44	Thus, our installation has been perfect.
04:48	Now, let us go back to the slides.
04:51	I will now explain why Java is useful.
04:55	Java is simple.
04:57	Java is object oriented.
04:59	It is platform independent.
05:01	It is safe. Java has high performance.
05:04	Java is multi–threaded.
05:07	We will now go through some types and applications of Java.
05:11	JSP, or Java Server Pages: It is based on a code with normal HTML tags.
05:18	JSP helps in creating dynamic web pages.
05:22	Java Applets: It is used to provide interactive features to web applications.
05:28	J2EE or Java Enterprise Edition: Companies use J2EE.
05:33	It is useful to transfer XML structured documents.
05:38	JavaBeans: JavaBeans is a reusable software component.
05:43	It can be used to build new and advanced applications.
05:47	Mobile Java: It is used for various entertainment devices, such as mobile phone.
05:53	So, in this tutorial we learnt:
05:56	To install the JDK using Synaptic Package Manager.
05:59	To compile and run a Java program.
06:02	Benefits of using Java.
06:04	Types and Applications of Java.
