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 {
@Override
public 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 {
@Override
public 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....
