执行代码后算出来总是多3
package work2;
public class Part implements Runnable{
private int n = 800;

@Override

while(i <= n){

}
sell();
}
System.out.println(Thread.currentThread().getName()+"生产了："+m+"个");
}

Thread.sleep(1);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

System.out.println(Thread.currentThread().getName()+
"生产第"+ i++ +"个零件");
}
