is calling frame.repaint() at the end of the paint() method dangerous?

Question

Since repaint() calls paint(), isn't calling repaint() at the end of the paint() method using recursion endlessly? If so, why am I not getting a stack overflow error?

It's not actually a recursive call. Calling `repaint()` just enqueues an event that does the painting later. It's similar to calling `SwingUtilities.invokeLater(...)`. — Radiodef, May 29 '18 at 15:08

No, it's not dangerous, since it will just queue in a new paint request. It's actually well known practice when developing small games with swing :) At least it was at my university!

Be careful what you learn at university, their theory is a lot better than their practice. – Kayaman May 29 '18 at 15:16
