线程的Thread与Runnabe_thread 同一个runnabe是-优快云博客

本文介绍了Java中实现多线程的三种方式：继承Thread类、实现Runnable接口以及使用匿名内部类。通过示例代码展示了如何创建并启动线程，分别在主线程和子线程中进行循环打印，演示了多线程并发执行的效果。

Thread是类Runnabe是接口。

所有Thread可以通过继承来获得，Runnabe要通过实现类来获得。

Runnabe

package ldb0715.night.demo02;

public class TestMyRunnabe {
	public static void main(String[] args) {
		MyRunnabe mr = new MyRunnabe();
		
		Thread t1 = new Thread(mr,"子线程1");
		Thread t2 = new Thread(mr,"子线程2");
		t1.start();
		t2.start();
		for (int i = 0; i < 50; i++) {
			System.out.println("==主线程id:"+Thread.currentThread().getId()+"===主线程名称:"+
					Thread.currentThread().getName()+"===="+i+"======");
		}
	}
}


package ldb0715.night.demo02;

public class MyRunnabe implements Runnable {

	@Override
	public void run() {
		for (int i = 0; i < 50; i++) {
			System.out.println("--子线程id:"+Thread.currentThread().getId()+"---子线程名称:"+
		Thread.currentThread().getName()+"-----"+i+"-----");
		}
		
	}
	
}

Thread

package ldb0715.night.demo01;

public class MyThread extends Thread {
	@Override
	public void run() {
		for (int i = 0; i < 50; i++) {
			System.out.println("---子线程id:"+Thread.currentThread().getId()+"---子线程名称:"
					+Thread.currentThread().getName()+"-----"+i+"-----------");
		}
	}
}


package ldb0715.night.demo01;

public class Demo01 {
	public static void main(String[] args) {
		/**
		 * 1.使用Thread 创建线程,使用start()方法运行
		 */
		MyThread mt = new MyThread();
		mt.setName("这是我的子线程");
		mt.start();
		for (int i = 0; i < 50; i++) {
			System.out.println("===主线程id:"+Thread.currentThread().getId()+"===主线程名称:"
					+Thread.currentThread().getName()+"====="+i+"===========");
		}
		
	}
}

用匿名内部类实现

package ldb0715.night.demo02;

public class TestMyRunnabe2 {
	public static void main(String[] args) {
		
		//Thread t1 = new Thread(mr,"子线程1");
		//mr相当于==>new Runnable()
		Thread t1 = new Thread(new Runnable() {
			
			@Override
			public void run() {
				// TODO Auto=generated method stub
				for (int i = 0; i < 50; i++) {
					System.out.println("==子线程id:"+Thread.currentThread().getId()+"==子线程名称:"
				+Thread.currentThread().getName()+"===="+i+"===");
				}
			}
		},"我的子线程1");
		
		Thread t2 = new Thread(new Runnable() {
			
			@Override
			public void run() {
				// TODO Auto=generated method stub
				for (int i = 0; i < 50; i++) {
					System.out.println("==子线程id:"+Thread.currentThread().getId()+"==子线程名称:"
							+Thread.currentThread().getName()+"==="+i+"====");
				}
			}
		},"我的子线程2");
		//调用线程  只有通过Thread对象才可以调用
		t1.start();
		t2.start();
		
		for (int i = 0; i < 50; i++) {
			System.out.println("==主线程id:"+Thread.currentThread().getId()+"==主线程名称:"
					+Thread.currentThread().getName()+"==="+i+"====");
		}
		
		
	}
}
