线程优先级setPriority()  默认是5 最大是10 最小是1  相对来说得到的枪战CPU资源的机会多，也不是特别准确

 

package 线程优先级;

public class PriorityTest {
    public static void main(String[] args) {
        
        Priority pt = new Priority();
        Priority pt1 = new Priority();
        Priority pt2 = new Priority();
//        线程优先级setPriority()  默认是5 最大是10 最小是1  相对来说得到的机会多，也不是特别准确
        /*
        System.out.println(pt.getPriority());
        System.out.println(pt1.getPriority());
        System.out.println(pt2.getPriority());

        pt.setPriority(1);
        pt1.setPriority(5);

        pt.start();
