I was hoping someone could tell me if you could parse a long into an int and if you can, how you do it??

You mean something like this:
long lg = 5000;
int i = (int)lg;
All you need to do is cast the long into an int. If the long is too long for the int then you will get a wrong result.

Kassi, Thomas is correct in that you only need to perform a cast to convert the number. He also points out the downside to the "narrowing conversion".
If you are concerned that the number is converted correctly, you can check that the long value is not greater than Integer.MAX_VALUE before attempting the cast, or you can verify that i == lg after the conversion.
 
Don't get me started about those stupid light bulbs.
