线程的创建

线程的创建

代码如下（示例）：

package com.vetor.x;

public class Example12_2 {
	public static void main(String[] args) {
		/**
		 * 
		 * 用继承Runnable的类对象来创建线程对象
		 */
		Thread speakElephant;
		Thread speakCar;
		
		ElephantTarget elephant;
		CarTarget car;
		elephant = new ElephantTarget();
		car = new CarTarget();
		
		speakElephant = new Thread(elephant);
		speakCar = new Thread(car);
		
		speakElephant.start();
		speakCar.start();
		
		for(int i = 1;i<=15;i++) {
			System.out.println("主人"+i+"  ");
		}

	}
}

public class ElephantTarget implements Runnable{
	public void run() {
		for(int i = 1;i<=20;i++) {
			System.out.println("大象"+i+"  ");
		}
	}

}

public class CarTarget implements Runnable {
	public void run() {
		for(int i =1;i<=20;i++)
		{
			System.out.println("轿车"+i+"  ");
		}
	}

}

总结

1, 用继承Runnable的类对象来创建线程对象
2, 直接继承Thread类
