创建线程的方式

创建了线程都是重写run()方法，调用start()方法

 

1.继承Thread类

public class thread extends Thread {
    public thread() {
        super();
    }

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

    @Override
    public void run() {
        while(true) {
            System.out.println(getName() + "开启线程！");
            try {
                Thread.sleep(200);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            System.out.println( isInterrupted());
        }
    }

}

2.继承Runnable接口

package Runnableimpl;

/**
 * @Author:
 * @BuildTime:
 * @ChangeTime:
 * @Function:
 **/
public class runnableimpl implements Runnable{

    @Override
    public void run() {
        System.out.println("线程启动！");
    }
}

3.内部类的方式

package Demo;


public class demo1 {
    public static void  main(String[] args){
        new Thread(){
            @Override
            public void run(){
                System.out.println("线程启动！");
            }
        }.start();
    }
}

4.继承Callable接口

package Demo;

import java.util.concurrent.Callable;


public class demo2 implements Callable<Integer> {
    @Override
    public Integer call() throws Exception {
        System.out.println("线程启动--callable");
        Thread.sleep(3000);
        return 10;
    }
}

5.定时器Timer创建线程

package Demo;

import java.util.Timer;
import java.util.TimerTask;


public class demo3 {
    public static void main(String[] args) {
        Timer timer = new Timer();
        timer.schedule(new TimerTask() {
            @Override
            public void run() {
                System.out.println("线程3已经启动");
            }
        }, 1000, 1000);
    }

}

6.Executors创建线程池创建线程
