Java actionPerformed and global variables

25 New Member
Hi everybody,
I have a question. In java I have a class which has global variables. Also, in this class I have an actionPerformed method implemented, which is called every time some event happens. Now, in actionPerformed, I set these variables. Although inside actionPerformed their values do appear to change, after it is finished, the values go back to their old ones. Why is this happening? How do I get the values to stay? Please help..

I don't know what you mean: Java does not have "global variables". The absolute best way to get help on a forum is to post a Short, Self Contained, Correct (Compilable), Example. Try that.

My blind guess is that you've defined local variables in your actionPerformed()
method having the same names as the static (not 'global') variables in your class.

kind regards,
