Please help me! Error message : java.lang.OutOfMemoryError

Question

Hello, I am a new learner on Java ME. I have done a simple shooting game in Java ME. I am using multiple threads on that and when I run the program in Sun Java Wireless Toolkit, the error message "java.lang.OutOfMemoryError" appear. May I know what is the cause of this problem? Is it because of too many threads running at the same time or ..? Any suggested solution on this? Thanks.

Hello,
I try to assign all class object as null, but the problem still there. My game has 3 stages. For example, after the first stage, I would like to clear the memory buffer like the heap memory, then only load the second stage. Otherwise, the memory may not enough when the stages increased. So, is there any other way to clear the buffer for garbage collection?
In my game, it has a menu. The menu has the option like "New Game", "Help", "Exit". Whenever the game is start, the menu will add-in another option - "Continue", which will allows user back to the game and continue it.
Everytime when I select "New Game", the game will start running, and when I press for menu, the game will pause automatically and then show the menu list. In this case, the game is still in the memory, but in paused state. If I choose "New Game" from the menu, it means it will restart a new game.
My problem is that when I restart a new game, the heap memory still keeping the previous game. How could I delete the previous game's memory, so that whenever the new game is selected, the heap memory that store previous game would be cleared and the memory buffer will always store the current game only?
