如何清除/重置 JFrame

How to clear/ reset a JFrame(如何清除/重置 JFrame)

问题描述

Me and my friend have decided to work on a card game which cycles between 3 screens (Player1HandScreen, Player2HandScreen and FightScreen).

Once Player1 has chosen their card from Player1HandScreen, Player1HandScreen leads to Player2HandScreen where Player2 does the same. then Player2HandScreen leads to FightScreen where the two cards are compared and one player is declared the winner of that round.

The problem we are having is that once the round ends we want to clear Player1HandScreen as well as the Player2HandScreen once refreshing our parameters we are having trouble updating the GUI successfully.

We have have tried to use removeAll(), but we can't get it to repaint() or validate().

We have also looked into super.paintComponents(g) and updateUI() but both have left us with crushed hopes and dreams.

if you remove any JComponent(s) from Container (only once on the end), is needed tell to Container for,

removeAll()//or remove(JComponent)
revalidate();
repaint();
