大家好，我想知道为什么我的2个gui上的jbuttons叫colin，我在这里将无法正常工作 当我点击确定按钮调用GUI命名为userino_frame这会出现好，但当我点击清除按钮来调出motor_frame gui gui给我例外线程“AWT-EventQueue-0”java.lang.UnsupportedOperationException：尚未实现的消息 我已经尝试了几种方法来改变这一点，但无济于事，因为我想做的事情被调出时，按下按钮2 JButtons 2 GUI

你还应该发布stacktrace的例外。这使得调试更容易。 – Alderath 2012-08-09 13:35:26
请学习[Java命名约定]（http://www.oracle.com/technetwork/java/javase/documentation/codeconvtoc-136057.html）并严格遵守它们:-) AFAICS，您将初始化一个新的' JFrame的每个按钮点击，你不应该这样做，而是简单地检查实例是否已经显示，并提供一个窗口，如果它不是，虽然mKorbel的答案太棒了话题，从不使用两个'JFrame'。否则这里是一个[示例]（http://stackoverflow.com/a/9443609/1057230）来说明我在说什么:-) – 2012-08-09 16:40:25
