4.多线程之间的通讯
什么是多线程的通讯？
多线程之间的通讯，其实就是多个线程同时去操作同一个资源，但是操作动作不同
package com.jlong;
class User {
public String name;
public String sex;
public boolean flag=false;
}
class InputThread extends Thread {
private User user;
public InputThread(User user) {
this.user = user;
}
int cout = 0;
@Override
public void run() {
while (true) {
synchronized (user) {
if(user.flag){
try {
user.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
if (cout == 0) {
user.name = "jLong";
user.sex = "男";
} else {
user.name = "燕子";
user.sex = "女";
}
cout = (cout + 1) % 2;
user.flag=true;
user.notify();
}
}
}
}
class OutputThread extends Thread {
private User user;
public OutputThread(User user) {
this.user = user;
}
@Override
public void run() {
while (true) {
synchronized (user) {
if(!user.flag){
try {
user.wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
System.out.println(user.name + "--" + user.sex);
user.flag=false;
user.notify();
}
}
}
}
public class ThreadDemo01 {
public static void main(String[] args) {
User user = new User();
InputThread inputThread = new InputThread(user);
OutputThread outputThread = new OutputThread(user);
inputThread.start();
outputThread.start();
}
}
