This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with. And what we have so far doesn;t make a lot of sense.
Perhaps if you give us sample code or pseudocode to explain what you are trying to do that might help us understand?

You cannot normally recover from Unchecked Exceptions so it is difficult for the programmer to anticipate them at code creation time. See Unchecked Exceptions The Controversy (The Java™ Tutorials > Essential Classes > Exceptions)[^].
