JAVA线程优先级

可以用setPriority来设置线程的优先级，getPriority取得线程的优先级：

package priority;

import sharevar.Machine;

public class priority extends Thread {
    private static StringBuffer log=new StringBuffer();
    private static int count=0;
    
    public void run() {
        for (int a=0;a<20;a++) {
            log.append(currentThread().getName()+":"+a);
            if (++count %10==0) log.append("\n");
        }
    }

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Machine m1=new Machine();
        Machine m2=new Machine();
        m1.setName("m1");
        m2.setName("m2");
        
        Thread main=Thread.currentThread();   //获得主线程
        //查看和设置线程的优先级
        System.out.println("default priority of main:"+main.getPriority());
        //打印m2线程默认优先级
        System.out.println("default priority of m1:"+m1.getPriority());
        //打印m2线程默认优先级
        System.out.println("default priority of m2:"+m2.getPriority());
        
        m2.setPriority(Thread.MAX_PRIORITY);
        m1.setPriority(Thread.MIN_PRIORITY);
        
        m1.start();
        m2.start();
        System.out.println(log);
    }

}
