Installing Java on Ubuntu 64 bit

Solution 1:

On the command line, type:

$ sudo apt-get install openjdk-7-jre

OR

1) Goto http://www.java.com/en/download/linux_manual.jsp 2) Download the 64-bit package.

Installation:

Change to the directory in which you want to install. Type:

cd <directory path name>

For example, to install the software in the /usr/java/ directory, Type:

cd /usr/java/

Note about root access: To install Java in a system-wide location such as /usr/local, you must login as the root user to gain the necessary permissions. If you do not have root access, install Java in your home directory or a subdirectory for which you have write permissions. Move the .tar.gz archive binary to the current directory.

Unpack the tarball and install Java:

tar zxvf jre-7u7-linux-x64.tar.gz

The Java files are installed in a directory called jre1.7.0_07 in the current directory. In this example, it is installed in the /usr/java/jre1.7.0_07 directory. When the installation has completed, you will see the word Done. Delete the .tar.gz file if you want to save disk space.
