java - StackOverflow Error when running -

my code compiles when run it, weird error message pops up.

the error message says

"java.lang.stackoverflowerror:null(in sun.awt.win32graphicsconfig).

what it's supposed print out panel 4x10 of button array button list stored info far. buttons don't right that's fine because care actual graphic now. there class goes array list can put in comments if needed.

here code:

jbtnumbuttons[n][m].addactionlistener(new culminatingprojectgui());

here problem. create new instance of culminatingprojectgui, , in constructor create again , again. should consider following:

jbtnumbuttons[n][m].addactionlistener(this);
