1.8.3suspend与resume方法的缺点--不同步

package com.cky.bean;

/**
 * Created by edison on 2017/12/3.
 */
public class MyObject {
    private String usrName = "1";
    private String pwd ="11";
    public void setValue(String u, String p) {
        this.usrName = u;
        if (Thread.currentThread().getName().equals("a")) {
            System.out.println("停止a线程");
            Thread.currentThread().suspend();
        }
        this.pwd =p;
    }

    public void printNameAndPwd() {
        System.out.println(usrName +":"+pwd);
    }
}

package com.cky.test;

import com.cky.bean.MyObject;

/**
 * Created by edison on 2017/12/3.
 */
public class Run2 {
    public static void main(String[] args) {
        try {
            final MyObject myObject = new MyObject();
            Thread th1=new Thread(){
                @Override
                public void run() {
                    super.run();
                    myObject.setValue("a", "aa");
                }
            };
            th1.setName("a");
            th1.start();
            Thread.sleep(500);
            Thread th2=new Thread(){
                @Override
                public void run() {
                    super.run();
                    myObject.printNameAndPwd();
                }
            };
            th2.start();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }


    }
}

停止a线程

结果不同步，程序中使用suspend()得注意。
