| 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? |
| 00:14 | * 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. |
| 05:02 | * 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. |
