then run:

sudo mv jdk-6u25-linux-x64.bin /home/ramu

and it will work. the user admin does not have write access to ramu's home folder.

Please note, however, that the method you are using is not the recommended method for installing Java. See It seems that you're trying to install the proprietary JDK from Oracle. You might consider using the free open source Java implementation OpenJDK, which is also official. However, if you want to use the proprietary JDK, you can install that using Ubuntu packages as well.
