java_多线程_优先级

java多线程示例展示优先级源代码：

package control;

/**
 * 功能:龟兔赛跑
 *            线程控制优先级别
 * 
 *         总结:怎么设置优先级？
 *             setPriority 
 *             通过设置优先级，数字越大的优先级别越高(1-10)  获取cpu概率大
 *             默认优先级是5
 *             final static 
 *             MIN_PRIORITY  1
 *             MAX_PRIORITY  10
 *             通过写到run方法的设置优先级 还有启动线程设置优先级  在run方法中设置的生效

public class TestThread1 {
    public static void main(String[] args) {
        TortoiseThread tt = new TortoiseThread("乌龟线程");
        //设置线程优先级
        tt.setPriority(2);
        tt.start();
        
        RabbitRunnable rr = new RabbitRunnable();
        Thread tr = new Thread(rr);
        tr.setName("兔子线程");
        //设置线程优先级
        tr.setPriority(9);
        tr.start();
        
        
    }
}

乌龟线程：TortoiseThread.java

package control;

import java.util.Scanner;

public class TortoiseThread extends Thread{
    private String name;
    public TortoiseThread(){
    }
    public TortoiseThread(String name){
        super(name);
    }
    int count = 0;
    public void run() {
        setPriority(10);
        while(true){
            count++;
            Scanner sc = new Scanner(System.in);
            System.out.println("乌龟领先了====加油。。。"+getName() +" "+getPriority()+" count:"+count);
        }
    }
}

兔子线程：RabbitThread.java

package control;

/**
 * 兔子的线程
 * @author superdrew
 */
public class RabbitRunnable implements Runnable{
    int count = 0;
    public void run() {
        Thread.currentThread().setPriority(5);
        while(true){
        count++;    
            System.out.println("兔子领先了-----快加油!"+
        Thread.currentThread().getName()+" "+Thread.currentThread().getPriority()+" count:"+count);
        }
    }    
}
