虚拟线程是Java17+开始的新功能，虚拟线程由JVM负责管理和维护，在用户层非系统层创建。非常轻量，用完即扔。

Java中的虚拟线程.java

package com.example.terminal;

import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.Executors;
import java.util.concurrent.ThreadFactory;

/**
 *
 */
public class Main {
    public static void main(String[] args) {
        virtualThread1();
        virtualThreadFactory();
    }

    public static void virtualThread1() {
        System.out.println("----测试虚拟线程第一种方式----");
        try(var exe = Executors.newVirtualThreadPerTaskExecutor()){
            for (int i = 0; i < 100; i++) {
                int value = i;
                exe.submit(() -> {
                    System.out.println("我是编号" + value);
                });
            }
        }
        System.out.println("第一种虚拟线程测试完成!");
    }

    public static void virtualThreadFactory() {
        System.out.println("我在执行ThreadFactory相关测试");
        ThreadFactory factory = Thread.ofVirtual().name("demo", 1).factory();
        List<Thread> threads = new ArrayList<>(10);
        for (int i = 0; i < 10; i++) {
            int value = i;
            var thread = factory.newThread(() -> {
                System.out.println("工厂方法-我执行了"+value);
            });
            threads.add(thread);
        }

        threads.forEach(Thread::start);
        threads.forEach(thread -> {
            try {
                thread.join();
            } catch (InterruptedException e) {
                throw new RuntimeException(e);
            }
        });
    }
}
