Solution :

Since Oracle has moved the download link and requires login credentials to download older versions of java, follow the following steps to install java 7: 

1) Download latest java version from http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html. You will need to login. 

2) Delete jdk-7uXX-linux-x64.tar.gz from /var/cache/oracle-jdk7-installer/ where XX is the version number. 

3) Move the downloaded version into /var/cache/oracle-jdk7-installer/ using the following command

sudo mv jdk-7u(downloadedversion)-linux-x64.tar.gz /var/cache/oracle-jdk7-installer/

4) Now run the following command

sudo apt-get install oracle-java7-installer
