Question

所以我的问题是setHit方法不起作用，如果我得到一个匹配它不会识别它并且letUnclick方法运行我只想将按钮setText设置为HIT，当它们匹配时，如果不是继续我究竟做错了什么？

Answer 1

显然，我的错误是比较 klicked [0] .getSelectedIcon（）== klicked [1] .getSelectedIcon（）

在eclipse调试器中我发现这些不相等，所以我将其改为

点击[0] .getSelectedIcon（）。的toString（）。等于（点击[1] .getSelectedIcon（）。的toString（））

现在，当我得到一场比赛时它会起作用。

ActionListener中的GUI内存游戏（不能成对）
