线程的2中基本用法

这里列出了java线程的2种基本使用方法：

Runner接口

public class TestThread1 {
	public static void main(String args[]) {
		Runner1 r = new Runner1();
		Thread t = new Thread(r);
		t.start();
		
		for(int i=0; i<15; i++) {
			System.out.println("Main Thread:------" + i);
		}
	}
}

class Runner1 implements Runnable {

	public void run() {
		for(int i=0; i<15; i++) {	
			System.out.println("Runner1 :" + i);
		}
	}
}
/**
结果：
Main Thread:------0
Runner1 :0
Main Thread:------1
Runner1 :1
Main Thread:------2
Runner1 :2
Main Thread:------3
Runner1 :3
Main Thread:------4
Runner1 :4
Main Thread:------5
Runner1 :5
Main Thread:------6
Runner1 :6
Main Thread:------7
Runner1 :7
Main Thread:------8
Runner1 :8
Main Thread:------9
Runner1 :9
Main Thread:------10
Main Thread:------11
Runner1 :10
Main Thread:------12
Runner1 :11
Main Thread:------13
Runner1 :12
Main Thread:------14
Runner1 :13
Runner1 :14
**/

Thread

public class TestThread1 {
	public static void main(String args[]) {
		Runner1 r = new Runner1();
		r.start();

		
		for(int i=0; i<15; i++) {
			System.out.println("Main Thread:------" + i);
		}
	}
}


class Runner1 extends Thread {
	public void run() {
		for(int i=0; i<15; i++) {	
			System.out.println("Runner1 :" + i);
		}
	}
}
/**
结果：
Main Thread:------0
Main Thread:------1
Runner1 :0
Main Thread:------2
Runner1 :1
Main Thread:------3
Runner1 :2
Main Thread:------4
Runner1 :3
Main Thread:------5
Runner1 :4
Main Thread:------6
Runner1 :5
Main Thread:------7
Runner1 :6
Main Thread:------8
Runner1 :7
Main Thread:------9
Runner1 :8
Main Thread:------10
Runner1 :9
Runner1 :10
Runner1 :11
Runner1 :12
Runner1 :13
Runner1 :14
Main Thread:------11
Main Thread:------12
Main Thread:------13
Main Thread:------14

其实一个cup在同一时间上只有一个线程执行，只是执行速度很快，给人一种同时执行的感觉。

线程有一些方法及知识点：

sleep()

interrupt()

stop()

join()

yield()

优先级设置
