Program to create a simple calculator using Java AWT. To solve the above problem, we simply override update() and make sure the background is not cleared: This is because update is called and update clears the background. #What is awt in java in hindi codeHowever, this code still has a problem: every time the frame is re-sized, the background is cleared (overwritten).
