使用JTable遇到的古怪问题

[rocket_11]

利用继承自 DefaultTableModel 的类 ServerTableModel 构造 JTable ，在 ServerTableModel中加入了操作模型的方法，运行结果正常，但是抛出异常如下：

并不是我自己写的代码抛出的异常，请问可能是哪里出了问题啊:-(

占据有利地形－－沙发
呵呵舒舒服服地帮"rocket_11()"顶一下

用eclipse自己debug啊。看看数组什么时候越界了。在执行哪个方法的时候出现了23。哪个又是3

[iehanbin]

肯定是调用table的getValueAt(int row, int column) 方法时传入的参数超出了table实际的row或者column。

这个是Swing自己在绘制表格时报的错
我也出现过,很难解决的
你将表格的数据改变,然后fire事件通知swing; swing会在Thread中绘制.
但是Swing是线程不安全的.这个错误很可能是因为你在不安全的地方操作了Table的数据.

感覺~~有點像windows的消息循環出了問題

检查下你的组件是不是有些没有初始化然后在线程中使用了

ni你打印出来的栈信息不完整

我感觉你在用数据模型组织数据时，用了集合，而且是Vector，你查一下，程序中有没有地方是溢出的，比如，本来你的Vector中只有三个数据，而你却引用了第五个，这就是溢出，就会出这样的错误。
