java基础---->多线程之ThreadLocal（七）

ThreadLocal的简单实例

一、ThreadLocal的简单使用

package com.linux.huhx.thread2;

import java.util.Random;

public class ThreadLocalerTest {
private static ThreadLocal<Integer> threadLocal = new ThreadLocal<>();

public static void main(String[] args) {
for (int i = 0; i < 2;i++) {
new Thread(new Runnable() {
@Override
public void run() {
int randomValue = new Random().nextInt(9999);
System.out.println(Thread.currentThread().getName() + ", value: " + randomValue);
threadLocal.set(randomValue);

new GetA().get();
new GetB().get();
}
}).start();
}
}

private static class GetA {
public void get() {
int value = threadLocal.get();
System.out.println("A from " + Thread.currentThread().getName() + ", get data " + value);
}
}

private static class GetB {
public void get() {
int value = threadLocal.get();
System.out.println("A from " + Thread.currentThread().getName() + ", get data " + value);
}
}
}

Thread-1, value: 2667
Thread-0, value: 9611
A from Thread-0, get data 9611
A from Thread-1, get data 2667
A from Thread-0, get data 9611
A from Thread-1, get data 2667
