前言：学习受教了，二话不说，贴上干货，走起来----【在2个线程之间传递任意数据类型的数据】

import java.util.concurrent.Exchanger;

public class ThreadA extends Thread {

    public ThreadA(Exchanger<String> exchanger){
        super();
        this.exchanger = exchanger;
    }
    @Override
    public void run(){
        try{
            System.out.println("在线程A中得到线程B的值==="+exchanger.exchange("AAAAAAA"));
        }catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}
