代码如下

注意：需要导入commons.io 包，需浏览器下载相关文件。

package com.thread;

import org.apache.commons.io.FileUtils;

import java.io.File;
import java.io.IOException;
import java.net.URL;

public class TestDownPicture extends Thread{
    private String url;
    private String name;
    public TestDownPicture(String url, String name){
        this.url = url;
        this.name = name;
    }
    public void run(){
        DownLoad1 downLoad = new DownLoad1();
        downLoad.down(url,name);
        System.out.println(name+"下载完成");
    }

    public static void main(String[] args) {
        TestDownPicture testDownPicture = new TestDownPicture("https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA19W5DS.img?w=680&h=470&m=6","1.jpg");
        TestDownPicture testDownPicture1 = new TestDownPicture("https://dfzximg01.dftoutiao.com/minimodify/20230417/640x359_643cbd47a71fc.jpeg", "2.jpg");
        TestDownPicture testDownPicture2 = new TestDownPicture("https://dfzximg01.dftoutiao.com/minimodify/20230417/640x427_643cbd48a2b17.jpeg", "3.jpg");

        testDownPicture.start();
        testDownPicture1.start();
        testDownPicture2.start();
    }
}

//下载器
class DownLoad{
    //下载方法
    public void down(String url,String name){
        try {
            //文件工具包下的 复制URL到文件
            FileUtils.copyURLToFile(new URL(url),new File(name));
        } catch (IOException e) {
            e.printStackTrace();
            System.out.println("IOException,down方法出现问题");
        }
    }
}
