在eclipse里运行这个程序会报错，但不知道是什么问题。请教下这里大虾们

CMD中编译正常，Eclipse没装

private static JProgressBar progressBar = new JProgressBar();

楼主要看看swing container，先放frame，panel，然后其他的label，radiobox啥的。我大概改了一下

import java.awt.*;
import javax.swing.*;
//import MyWindowListener;
@SuppressWarnings("serial")
public class MyProgressBar extends JFrame
{
//private Container c;
JFrame f = new JFrame ("JProgressBarDemo");
JPanel p = new JPanel (new FlowLayout (FlowLayout.LEFT));
public static JProgressBar progressBar = new JProgressBar (JProgressBar.VERTICAL, 10, 100);
public static JLabel label;

@SuppressWarnings("deprecation")
public MyProgressBar()
{


super("MyProgressBar.java:JprogressBar TEst");


p.setPreferredSize (new Dimension (600,400));
//Container c=getContentPane();
//c.setLayout(new FlowLayout());
label =new JLabel("0.0%");
f.add(p);
p.add(progressBar);
p.add(label);
setSize(350,80);
show();
}
@SuppressWarnings("static-access")
public static void main(String args[])
{
MyProgressBar app= new MyProgressBar();
app.addWindowListener(new MyWindowListener());
int m=Integer.parseInt(String.valueOf(10));//args[0]
int max=app.progressBar.getMaximum();
app.progressBar.setStringPainted(true);
app.progressBar.setString("random process");
for (int i=0; i<10; i++)
{
while (true)
{
int n=(int)(Math.random()*m);
if (n==7)
{

if(cur<max) progressBar.setValue(cur+30);

import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
class MyWindowListener extends WindowAdapter
{
public void windwosClosing(WindowEvent e)
{
System.exit(1);

}
这段楼主是不是想重写WindowAdapter里的windowClosing方法啊
方法名错了
别的地方我没看

按你的这种方式改在eclipse里确实能运行出来，但无法到达我的目的。我是想做个类似进度条的效果。
