43.创建线程的两种方法

Posted 2020-07-14 许先

public class Test {

    public static void main(String[] args) {
        MyThread mt = new MyThread(); // 实例化线程对象
        mt.start();// 启动线程
    }
}

// 通过继承Thread类来创建线程
class MyThread extends Thread {
    private int count = 0;

    public void run() {
        while (count < 100) {
            count++;
            if (count % 2 == 0)
                System.out.println("count=" + count);
        }
    }
}

public class Test {

    public static void main(String[] args) {
          Thread thread = new Thread(new MyThread()); //创建线程实例
            thread.start(); //启动线程
    }
}

/**通过实现Runnable接口来创建线程类*/
 class MyThread implements Runnable{
    private int count=0;
    @Override
    public void run() {
        while(count<100){
            count++;
            if(count%2==0)
                System.out.println("count="+count);
        }    
    }
}
