java线程的优先级

使用public final void setPriority(int  newPriority)方法
  即可设置线程优先级

public  class TestThread extends Thread{ 

    @Override 
    public  void run() { 
        for (inti = 0; i <50; i++) { 
           System.out.println(this.getName() + "正在运行" + i); 
        } 
    } 
} 
 
public  class PrioTest { 
    public static  void main(String[] args) { 
        PrioThread pt = new PrioThread(); 
        PrioThread pt1 = new PrioThread(); 
        PrioThread pt2 = new PrioThread(); 
		
        //查看优先级，最大优先级为10，最小为1，正常为5 
        System.out.println(pt.getPriority()); 
        System.out.println(pt1.getPriority()); 
        System.out.println(pt2.getPriority());

        //输出 5 
        //给线程设置优先级 
        pt.setPriority(10); 
		
//      pt.start(); 
//      pt1.start(); 
//      pt2.start(); 
    } 
}
