目前我可以在点击它们时激活我的所有jButton 但是我的教授要求我只点击1个jButtons来激活最后两行jButtons。
e.g 如果按下“11”jButton，则应激活整行jButton，并在最后一行显示“SUMMARY”，在最后一行显示“12”，“15”....“32”。
请使用OUTPUT图像和我的代码作为参考。提前谢谢！

答案 0 :(得分：1)
所以，通过一些猜测工作，基本上如果你点击＆＃34;赢得＆＃34;按钮，这将突出显示rList中所有值的最后一行按钮。

相反，如果您真的需要选择所有其他值＆＃34;首先，你需要保持一个成功的数字＆＃34;匹配并比较当＆＃34;获胜＆＃34;点击了数值。
