多线程——实现Runnable接口实现一个多线程

实现Runnable接口实现一个多线程

Runnable接口源码：

package java.lang;
//Runnable接口源码只有一个run方法
public interface Runnable {public abstract void run();
}

实现Runnable的两个多线程类：

public class RunnableThread1 implements Runnable {@Overridepublic void run() {for (int i = 0; i < 5; i++) {System.out.println(Thread.currentThread().getName() + ":线程启动....");try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}}
}
public class RunnableThread2 implements Runnable {@Overridepublic void run() {for (int i = 0; i < 5; i++) {System.out.println(Thread.currentThread().getName() + ":线程启动....");try {Thread.sleep(2000);} catch (InterruptedException e) {e.printStackTrace();}}}
}

 

测试：

public class TestThread {public static void main(String[] args) {RunnableThread1 thread1 = new RunnableThread1();RunnableThread2 thread2 = new RunnableThread2();Thread t1 = new Thread(thread1, "线程1");Thread t2 = new Thread(thread2);// 线程2为系统命名// 不能再此处调用sleep()方法
t1.start();t2.start();}
}
结果：
Thread-0:线程启动....
线程1:线程启动....
线程1:线程启动....
Thread-0:线程启动....
线程1:线程启动....
线程1:线程启动....
Thread-0:线程启动....
线程1:线程启动....
Thread-0:线程启动....
Thread-0:线程启动....
