how can create jbutton in custom paint(graphics g) method in java?

answer: don't. never create or place components within of painting methods. these methods rendering images , rendering , should never used component creation or program logic.

this question xy problem:

i have created "game over!" page when user loses in game. under g.drawstring(...), trying create button user can click restart game. having trouble getting button appear , stay visible.

in you're asking solution specific code problem, when true best solution use different approach. suggest:

• create jpanel displays background image in paintcomponent method, not paint method per swing painting tutorials
• add jbutton jpanel add jpanel, , not in painting methods.
• you're better off creating separate jpanel this, , swap jpanels when needed via cardlayout.

other issues:

• never dispose of graphics object given jvm. doing breaks painting chain.
• you should call super's painting method inside of override painting chain can continue. if override paintcomponent per recommendation, should sure call super.paintcomponent(g) method within own override.
• never call repaint() within painting method. bad way try animation uncontrollable , risky.
• don't override update() while done awt painting, not used swing graphics or animation.
