}
public void paintComponent(Graphics g)

for(int com=0;com<ima.length;com++){if(ima[com]!=null)
g2D.drawImage(ima[com],0,0,this);}

}
public void run()
{
while(true)
{
pause(1500);
}
}
public void pause(int time){try{Thread.sleep(time);}catch(InterruptedException e){}}
}


为什么这个程序编译没问题
但运行时显示不了图片动画~？？
请指教~！
