## 鼠标事件导致jvm crash? 求救!!

yongxuanlai 2005-04-18 05:08:33

本人在ie下运行applet开发,运行以下的代码,试了n次,jvm系统都莫名其妙的crash(见后面);
当去掉 if (n == 2) 这段代码后运行却是对的,请问各位大侠这是为何>?有类似的经历吗?> 如何解决的啊?
非常感激!!

public class GraphCanvas extends Canvas
implements MouseListener, MouseMotionListener,ActionListener
{
public void mouseClicked(MouseEvent e) {
int n=e.getClickCount();
if (n == 2)
{
//......
}
else if(n==1)
{
//.......
}
}
