for reason, when click buttons, makes actionperformed method, program can't match of buttons actionevent, nothing works when of buttons pressed. took code out of paintcomponent , put in constructor, buttons don't show up. can please help?

move creation , init code out of paintcomponent() constructor
the code
next=new jbutton("next"); no=new jbutton("no"); yes=new jbutton("yes"); yes.addactionlistener(this); no.addactionlistener(this); next.addactionlistener(this); yes.setbounds(100,200,100,50); no.setbounds(300,200,100,50); next.setbounds(700,500,100,50); add(yes); add(no); add(next); in fact on each repaint recreates buttons , readd them. in actionperformed() button state changed (to show pressed state) , button recreated. , of course != clicked one.
