代码如下：

package MyThreadPack;

public class MyThread extends Thread {
    @Override
    public void run() {
        for (int i = 0;i<100;i++)
        {
            System.out.println(i);
        }
    }
}

package MyThreadPack;

public class MyThreadDemo01 {
    public static void main(String[] args)
    {
        MyThread my1 = new MyThread();
        MyThread my2 = new MyThread();

        my1.start();
        my2.start();
    }
}

package MyThreadPack;

public class MyThread extends Thread {
    @Override
    public void run() {
        for (int i = 0;i<100;i++)
        {
            System.out.println(getName()+","+i);
        }
    }
}

package MyThreadPack;

public class MyThreadDemo01 {
    public static void main(String[] args)
    {
        MyThread my1 = new MyThread();
        MyThread my2 = new MyThread();

        my1.setName("高铁");
        my2.setName("飞机");

        my1.start();
        my2.start();


    }

}

package MyThreadPack;

public class MyThread extends Thread {

    public MyThread(){}

    public MyThread(String name)
    {
        super(name);
    }


    @Override
    public void run() {
        for (int i = 0;i<100;i++)
        {
            System.out.println(getName()+","+i);
        }
    }
}

    }

}

      System.out.println(Thread.currentThread().getName());

    }

}

package MyThreadPack;

public class MyThread extends Thread {

    public MyThread(){}

    public MyThread(String name)
    {
        super(name);
    }


    @Override
    public void run() {
        for (int i = 0;i<100;i++)
        {
            System.out.println(getName()+","+i);
        }
    }
}

package MyThreadPack;

public class MyThreadDemo01 {
    public static void main(String[] args)
    {
      MyThread my1 = new MyThread("高铁");
      MyThread my2 = new MyThread("飞机");
      MyThread my3 = new MyThread("汽车");

//      System.out.println(my1.getPriority());
//        System.out.println(my2.getPriority());
//        System.out.println(my3.getPriority());

        //优先级最大为10，最小为1
        my1.setPriority(10);
        my2.setPriority(5);
        my3.setPriority(1);



      my1.start();
      my2.start();
      my3.start();

    }

}

        for (int i = 0;i<100;i++)
        {
            System.out.println(getName()+","+i);
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }

        td1.setName("Tom");
        td2.setName("Jack");


        Thread.currentThread().setName("Lily");

        td1.setDaemon(true);
        td2.setDaemon(true);

        td1.start();
        td2.start();

        for (int i = 0;i<10;i++)
        {
            System.out.println(Thread.currentThread().getName()+","+i);
        }
    }

}

package MyRunnablePack;

public class MyRunnable implements Runnable{
    @Override
    public void run() {
        for (int i  =0;i<100;i++)
        {
            System.out.println(Thread.currentThread().getName()+","+i);
        }
    }
}
