这是其中一段代码，我想密码的文本框实现失去焦点时实现密码校对检验
不过怎么出现Exception in thread "AWT-EventQueue-0" java.lang.UnsupportedOperationException: Not supported yet.
初学还没用过这个方法。各位大侠帮帮忙！！

问题一：
你只给text5添加了FocusListener
而你的focusLost方法中判断中却只写了事件源为text6的情况
理论上说，你的这个事件中的代码是永远不会触发的
你这两个地方至少要一致吧，或者给text也加一下FocusListener

问题二：
你既然实现了FocusListener，ActionListener这两个接口
那就必须把它们所有的方法都实现
就是这两个方法

	@Override
	public void actionPerformed(ActionEvent e) {
		// TODO Auto-generated method stub

	}

	@Override
	public void focusGained(FocusEvent e) {
		// TODO Auto-generated method stub

	}

也可能是楼主的代码没贴全

这是一段代码而已，那个ActionListener 我已经实现了，现在改为text6可以实现检验密码，不过为什么还是出现下面的错误呢我是用netsBean的

问题出在你的focusGained方法，这个方法你怎么写的……

}
我这样写对吗？
if(e.getSource()==text6){
是这一句错了吧，要怎么改，其实e的方法有几个，失去焦点的我不知写哪个，最后就写了e.getSource()

输入不一样时、TAB无法移动焦点。
