How to install JRE on Ubuntu

[abbase]

I have installed Ubuntu along with eclipse on my machine. Recently i had downloaded java.sun from the internet. I was trying to install JRE on my machine, but it doesn't get installed. Can any body tell me that how to install JRE on Ubuntu? Does any body have any idea about it? Let me know the correct way for installing JRE on Ubuntu machine. Would be grateful, if any body provides me the correct way for doing it. Thanks in advance.

Java applications are compiled to bytecode, which at runtime is either interpreted or compiled to native machine code for execution. This process requires you to download an executable file that includes all the files needed for the complete installation. You do not need to remain connected to the Internet during the installation. The file can also be copied to a computer that is not connected to the Internet.

First you need to check multiverse repository enabled or not after that open a terminal window. Note - you must have administrative permissions in order to install the Java 2 Runtime Environment. The download page provides the following two choices of installation. Continue based on your choice. Since you are going to be installing the JRE and the web browser plug-in, you’ll be using the following command from a terminal

sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts
