多线程交替打印

package org.example; public class Main { // 计数器 private static int count = 0; public static void main(String[] args) throws InterruptedException { // 线程 1 Thread thread1 = new Thread(() -> { while (count < 100) { // 尝试获取锁 synchronized (Main.class) { // Double Check if (count < 100 && count % 2 == 0) { System.out.println("线程 1 打印：" + (count + 1)); count++; } } } }); // 线程 2 Thread thread2 = new Thread(() -> { while (count < 100) { // 尝试获取锁 synchronized (Main.class) { // Double Check if (count < 100 && count % 2 != 0) { System.out.println("线程 2 打印：" + (count + 1)); count++; } } } }); // 启动线程 thread1.start(); thread2.start(); // 等待线程打印输出完成 Thread.sleep(10000); } }
