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. |
