Error Handling and Freeing-up Memory

Question

I'm trying to write my java programs as responsibly as possible. When an exception is caught and sent to my catch block, in order to properly free up memory do I need to set all objects (created prior to the error occurance in the try block) to null or does Java do this for me at the termination of the routine or thread? I used to do this in VB within my error handlers. For example, in VB, if I had created an XYZ object and an error occured later on, before I was done using object XYZ, as part of my error handler I would "Set XYZ = Nothing". Is something similar needed in Java?

Answer 1

Well it is always good to do a clean up routine you can do this by makeing a method that will set things to null and such and you also can use finally after the exception handler has exit and close streams and such in the finally {} catch also you can forcing finalization and carbage collection
here is a link for that

but I thank it is alway good programming practice to clean up after your self
ps I hope this helps
