I have a small application which conects to the database and wrote some 2d graphics. I track the memory usage, while I opening and close the next database, and I saw that memory usage is growing although I try to clean everything: shutdown the database, close the ResultSet, dispose the JFrames and finally I System.gc(). 1. In the case when my application close/open database file and create gui again which variables I need to initialized to null ? 2. How to see what variables are not null ? 3. which variables, can in your opinion, cause that memory usage grow? Is it database stuff, gui stuff (I know that I must dispose JFrames) or what?

Seems that I was badly describe the problem or my question is not on right place.
