简单线程问题（没输出）怎么办

Question

import java.awt.*;public class DDD extends Canvas implements Runnable
{ String t="ÅíΰÍòËê";
Thread s;
int x=40,y=10;
public DDD()
{
this.setSize(200,200);
this.setVisible(true);
    s=new Thread(this);
s.start();
} public void run()
{
Thread ss=Thread.currentThread();
while(s==ss)
{
try
{
s.sleep(1000);
x++;
}catch(InterruptedException i){i.printStackTrace();}
    repaint();
}
}

public void paint(Graphics g)
{
g.drawString(t,x,y);
} 
public static void main(String[] args)
{
Frame f=new Frame();
DDD d=new DDD();
f.add(d);
f.setSize(400,400);
f.setVisible(true); }
}
canvas要放在容器中才行。

Answer 1

谢谢
现在我想String对象可以滚动，怎么办啊

Answer 2

我用语句打印了来看
import java.awt.*;public class DDD extends Canvas implements Runnable
{ String t="彭伟万岁";
Thread s;
int x=-400,y=10;
public DDD()
{
    s=new Thread(this);
s.start();
} public void run()
{   System.out.println("cccccccccccccccccc");
Thread ss=Thread.currentThread();
while(s==ss)
{
 repaint();
try
{
   s.sleep(1000);
      System.out.println("bbbbbbbbbbbbbb");
}catch(InterruptedException i)
{i.printStackTrace();}
   
}
}

public void paint(Graphics g)
{
g.drawString(t,x,y);
} 
public static void main(String[] args)
{
DDD d=new DDD();
        System.out.println("aaaaaaaaa");
}
}有这样的结果
aaaaaaaaa
cccccccccccccccccc
bbbbbbbbbbbbbb
bbbbbbbbbbbbbb
bbbbbbbbbbbbbb
bbbbbbbbbbbbbb
bbbbbbbbbbbbbb
bbbbbbbbbbbbbb
bbbbbbbbbbbbbb
..
..
也就是说你
while(s==ss)
{
.....
}
有问题罗，s==ss总是成立
