Repaint seems not working when called multiple times from the same method

Why can’t you call paint () method directly instead of calling repaint () method?

Why cant we call paint (Graphics g) rather than repaint() ? Short answer: because then it would be called at the wrong time or possibly in the wrong thread (and without an appropriate Graphics). The Graphics object must be prepared and delivered by the JVM itself with help from the platform/operating system.
