多线程同步下在网络图片文件

此过程要导入commons-io-2.6数据包用于接收图片
package 线程;
import org.apache.commons.io.FileUtils;
import java.io.File;
import java.io.IOException;
import java.net.URL;
//练习Theard，实现多线程同步下载
public class TestThread2 implements Runnable{
    private String url;//网络图片地址
    private String name;//保存文件名

    public TestThread2(String url,String name) {
        this.name = name;
        this.url = url;
    }

    @Override
    public void run() {
        WebDownloader webdownloader=new WebDownloader();
        webdownloader.downloader(url,name);
        System.out.println("下载文件名;"+name);
    }
    //下载图片线程的执行体
    public static void main(String[] args) {
        TestThread2 testThread1=new TestThread2("https://pic.cnblogs.com/avatar/2665954/20211202224408.png","1.jpg");
        TestThread2 testThread2=new TestThread2("https://ucc.alicdn.com/pic/developer-ecology/95e2e220445d4496a7002804b858587e.png","2.jpg");
        TestThread2 testThread3=new TestThread2("https://files.cnblogs.com/files/sheng-jie/MVP_Logo.bmp","3.jpg");
            //使用Thread代理调用线程
        new Thread(testThread1).start();
        new Thread(testThread2).start();
        new Thread(testThread3).start();
        //谁先下载完成，就是先执行
    }
}
//下载器
class WebDownloader{
    //下载方法
    public void downloader(String url,String name){
        try {

                //将路径转换成图片文件

           FileUtils.copyURLToFile(new URL(url),new File (name));
        } catch (IOException e) {
            e.printStackTrace();
            System.out.println("io异常，downloader方法出现问题");
        }
    }
