what should i do?

It looks as though the files that you were downloading with apt-get are corrupted or have some other issue. The best way to solve your issue is to go to sun's website and download the java jdk package in .tar.gz format. This package should have either (I forget, sorry) an install script or a very handy text file telling you exactly how to handle putting java onto your machine. If you follow the script step by step you will then end up with java and will probably have fewer headaches than trying to reconfigure your apt-get repositories.
