解决方案
简单看你的code可以在每次移动后保持板状态的堆叠/列表。
要initalise很容易使用：堆栈＆LT; INT [] []＆GT; aStack =新的堆栈＆LT; INT [] []＆GT;（）;
创建复制你的板阵列的方法 getBoardCopy（）
然后为每个移动
aStack.push（getBoardCopy（））;
有关撤消按钮创建一组板的方法 setBoard（INT [] []乘坐（））然后就撤消时，调用此
setBoard（aStack.pop（））
I am making a Connect 4 Game in java and am a little stuck as to how to make an undo method for it. I know this can be done using either an ArrayList or a Stack but I am not too sure how to implement it. My code for the game and GUI can be seen below, any help would be greatly appreciated!

解决方案
Briefly looking at your code you could maintain a Stack/List of the board states after each move.
To initalise is easy use: Stack<int[][]> aStack = new Stack<int[][]>();
Create a method to copy your board array getBoardCopy()
Then for each move
aStack.push(getBoardCopy());
For undo button create a set board method setBoard(int[][] aBoard()) then just call this when undoing
setBoard(aStack.pop())
