java多線程的4種實現方式

標籤：實現   int   main   public   col   方法   adp   cut   dex   

1，繼承Thread類，重寫run方法；

public class Thread01 extends Thread{    public Thread01(){    }    public void run(){          System.out.println(Thread.currentThread().getName());    }    public static void main(String[] args){         Thread01 thread01 = new Thread01();         thread01.setName("繼承Thread類的線程1");        thread01.start();               System.out.println(Thread.currentThread().toString());      }}

2，實現Runnable介面，重寫run方法；

public class Thread02 {    public static void main(String[] args){         System.out.println(Thread.currentThread().getName());        Thread t2 = new Thread(new MyThread02());        t2.start();     }}class MyThread02 implements Runnable{    @Override    public void run() {        System.out.println(Thread.currentThread().getName()+"2--實現Runnable介面的線程實現方式");    }   }

3，實現Callable介面通過FutureTask封裝器來建立Thread線程；

 

4，通過線程池建立線程；

public class Thread04 {        private static int POOL_NUM =10;        public static void main(String[] args)throws InterruptedException {        ExecutorService executorService = Executors.newFixedThreadPool(5);        for (int i = 0; i < POOL_NUM; i++) {            RunnableThread  runnable =new  RunnableThread ();                         executorService.execute(runnable);        }        executorService.shutdown();    }}class RunnableThread  implements Runnable{         @Override    public void run()      {            System.out.println("4--通過線程池建立的線程：" + Thread.currentThread().getName() + " ");     }  }
