在使用suspend与resume方法时也容易出现因为线程的暂停而导致数据不同步的情况。
/**
* @author wuyoushan
* @date 2017/3/29.
*/
public class MyObject {
private String userName="1";
private String password="11";
public void setValue(String u,String p){
this.userName=u;
if(Thread.currentThread().getName().equals("a")){
System.out.println("停止a线程!");
Thread.currentThread().suspend();
}
this.password=p;
}
public void printUserNamePassword(){
System.out.println(userName+" "+password);
}
}
/**
* @author wuyoushan
* @date 2017/3/20.
*/
public class Run {
public static void main(String[] args) throws InterruptedException {
final MyObject myObject=new MyObject();
Thread thread1=new Thread(){
@Override
public void run() {
super.run();
myObject.setValue("a","aa");
}
};
thread1.setName("a");
thread1.start();
Thread.sleep(500);
Thread thread2=new Thread(){
@Override
public void run() {
super.run();
myObject.printUserNamePassword();
}
};
thread2.start();
}
}
运行结果如下:
停止a线程!
a 11
