我的代码未打印出来但可以正常工作

Question

public class MyThread{

    public MyThread(int m) {
        super();
    }

    public void run() {
        for (int x = 0; x < 201; x++) { 
            System.out.println("Thread Running" + x );       
        } 
    }

    public static void main(String[] args) {
        MyThread mt = new MyThread(200);
    }
}

The code runs, but it is not printing out. It is probably the constructor but the teacher told me to only make a public void run and a main method to allow the code to work.

Also let me know if I'm asking the wrong type of question, I tried looking at the 'How to ask questions' for better question asking.

Answer 1

Looks like you are missing the implements Runnable for MyThread. And then you need to start() your mt thread.

Answer 2

You have two options:

1. Extend Thread .

    public class MyThread extends Thread{ 

   Then call start() in main .

    mt.start(); 

2. Implement Runnable .

    public class MyThread implements Runnable{ 

   Then start a new Thread passing in your object, and call start() .

    Thread t = new Thread(mt); t.start();
