static public void main(String[]args){//看到没有不仅只有public static
consumer a=new consumer(1000,"a");//1000相当于1S么
a.start();
consumer b=new consumer(2000,"b");
b.start();
consumer c=new consumer(3000,"c");
c.start();
}
}
//结果不明白
consumer name:a
consumer name:c
consumer name:b
consumer name:a
consumer name:b
consumer name:a
consumer name:c
consumer name:b
consumer name:a
consumer name:c
consumer name:b
consumer name:b
consumer name:c
consumer name:c
谁能解释下线程！我就这块觉得难。

a.start(),b.start(),c.start()只是启动了三个线程，但是至于他们在运行的过程中谁先谁后是由操作系统进行调度的。

ls正解

1000是指MS！即是1秒！！因为创建的是三个不同对象的进程，因而他们的实例变量不会相互影响,各循环四次。至于一开先执行哪个线程，我认为是第一个a.start()先，而后来的执行顺序取决于各进程对CPU的竞争！由于C睡觉的时间较长，所以会出现
consumer name:a
consumer name:c
consumer name:b
consumer name:a
consumer name:b
consumer name:a
consumer name:c
隔了长久才再次轮到c

去看看Java编程思想，详细着呢！
