First, we will check that java is already install or not on our system?
java -version
As, we can see that the java is not install on our system, so we will downloads the Java binary installer from Oracle. (In this example, we will download & install the jdk, but the procedure is exactly the same for jre).
Transfer the downloaded file (jdk-6u32***) to the CentOS from Windows machine using WinSCP.
Now, move to the directory where you copy the jdk file(in my case, it is in tmp directory) and give execute permission to jdk file:
cd /tmp/ sudo chmod +x jdk-6u32-linux-x64-rpm.bin
Run the jdk file:
sudo ./jdk-6u32-linux-x64-rpm.bin
Apply the alternatives:
sudo alternatives --install /usr/bin/java java /usr/java/jdk1.6.0_32/bin/java 17000
We are done 
Check the installed version of java:
java -version
Hope this will help you!
Please Remember me in your prayers!
