多线程输出预计不到

-2

我是新来的Java和多线程的概念。这里是我的实验代码：多线程输出预计不到

public class Multithread implements Runnable { 

    Thread t; 

    public Multithread(int prior, String name) { 
     this.t = new Thread(this, name); 
     this.t.setPriority(prior); 
     this.t.start(); 
    } 

    public void run() { 
     for (int i = 1; i <= 5; i++) { 
      if (this.t.getName().equals("thread1")) { 
       System.out.println("First Child Thread Loop No " + i); 
      } 
      else { 
       System.out.println("Second Child Thread Loop No " + i); 
      } 

      try { 
       Thread.sleep(1000); 
      } catch (InterruptedException e) { 
       System.out.println(e); 
      } 
     } 
    } 

    public static void main(String[] args) { 
     new Multithread(10, "thread1"); 
     new Multithread(7, "thread2"); 
    } 
}

输出是：

First Child Thread Loop No 1 
Second Child Thread Loop No 1 
First Child Thread Loop No 2 
Second Child Thread Loop No 2 
Second Child Thread Loop No 3 
First Child Thread Loop No 3 
Second Child Thread Loop No 4 
First Child Thread Loop No 4 
Second Child Thread Loop No 5 
First Child Thread Loop No 5

嗯，我预计会有这样简单：

First Child Thread Loop No 1 
Second Child Thread Loop No 1 
First Child Thread Loop No 2 
Second Child Thread Loop No 2 
First Child Thread Loop No 3 
Second Child Thread Loop No 3 
First Child Thread Loop No 4 
Second Child Thread Loop No 4 
First Child Thread Loop No 5 
Second Child Thread Loop No 5

我期望能获得前总是执行第一线第二个线程。请解释我的输出。提前致谢。

我永远不会理解这些问题。如果你想要一个特定的执行顺序，为什么你使用线程？ – EJP

@EJP我认为这种程序只是一个不懂线程并想学习的人编写的测试。 –

@Patricia雅正好。我只是想学习与多个线程 –
