Answer 1

You might have extracted the jdk-7-linux-x64.tar.gz file to the "jdk" directory. Now, inside this directory, you will find a directory called "bin". And the "java" binary would resides at this location.

So, add the below lines to the file ~/.bash_profile file with the logged in user (in our current scenario abhishek).

export JAVA_HOME=$HOME/Desktop/jdk    
export PATH=$JAVA_HOME/bin:$PATH

Save the file and run the below command at the command prompt.

$ cd 
$ . .bash_profile

Now, run the below commands for knowing where from the java is being picked

$ which java
$ java -version

Answer 2

yum install java-1.7.0-openjdk-devel

and then do,

java -version
