推荐答案
这是更好地使用的方法公共无效的Dispose()
It's better to use the method public void dispose()
<一个href=\"http://stackoverflow.com/questions/1407161/why-should-you-have-to-dispose-a-java-awt-window-that-goes-out-of-scope\">Why你应该有处置()一java.awt.Window中的超出范围?
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent we) {
dispose();
}
}
);
