问个线程Join问题

Question

运行下面的代码你会发现：先输出k的循环，然后j、i的循环相间输出
有没有办法先输出k的循环，然后输出j的循环，再输出i的循环？
而且是不修改MyThread的代码public class JoinThread
{
    public static void main(String[] args)
    {
        
        MyThread myThread = new MyThread();
        myThread.start();
        try
        {
            myThread.join();
        }
        catch(Exception ex)
        {
            ex.printStackTrace();
        }
        for(int i = 0; i < 100; i++)
        {
            System.out.println("i = " + i);
        }
    }
    
    private static class MyThread extends Thread
    {
        public void run()
        {
            for(int k = 0; k < 100; k++)
            {
                System.out.println("k = " + k);
            }
            
            Thread thread = new Thread()
            {
                public void run()
                {
                    for(int j = 0; j < 100; j++)
                    {
                        System.out.println("j = " + j);
                    }
                }
            };
            thread.start();
        }
    }
}

Answer 1

在 thread.start(); 
下面加上 thread.join();让外层的run等待内部的线程运行完再退出.

Answer 2

public class JoinThread 
{ 
    public static void main(String[] args) 
    { 
        
        MyThread myThread = new MyThread(); 
        myThread.start(); 
        try 
        { 
            myThread.join(); 
        } 
        catch(Exception ex) 
        { 
            ex.printStackTrace(); 
        } 
        for(int i = 0; i < 5; i++) 
        { 
            System.out.println("i = " + i); 
        } 
    } 
    
    private static class MyThread extends Thread 
    { 
        public void run() 
        { 
            for(int k = 0; k < 5; k++) 
            { 
                System.out.println("k = " + k); 
            } 
            
            Thread thread = new Thread() 
            { 
                public void run() 
                { 
                    for(int j = 0; j < 5; j++) 
                    { 
                        System.out.println("j = " + j); 
                    } 
                } 
            }; 
            thread.start(); 
            try{
            thread.join();
            }catch(InterruptedException e){}
        } 
    } 
}
