创建线程的两种方法

第一种：继承Thread类创建线程

public class MyThread1 extends Thread {@Overridepublic void run() {for (int i = 0; i < 100; i++) {System.out.println("thread1:"+i);}}}

第二种：实现Runnable接口创建线程

public class MyRunnable1 implements Runnable{@Overridepublic void run() {for (int i = 0; i < 100; i++) {System.out.println("Runnable1:"+i);}}}

在主方法实现效果

public class ThreadTest{public static void main(String[] args) throws InterruptedException {/*//继承Thread类创建线程MyThread1 t1 = new MyThread1();MyThread2 t2 = new MyThread2();t1.start();t2.start();*///实现Runnable接口创建线程Thread r1 = new Thread(new MyRunnable1());Thread r2 = new Thread(new MyRunnable2());r1.start();
