Java批量下载生成zip文件

import java.io.File;
import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.util.zip.ZipEntry;

import java.util.zip.ZipOutputStream; 

public class ZipOutputStreamDemo {

    public static void main(String[] args) throws Exception {

       byte[] buffer = new byte[1024];

       //生成的ZIP文件名为Demo.zip

       String strZipName = "Demo.zip";

       ZipOutputStream out = new ZipOutputStream(new FileOutputStream(strZipName));

       //需要同时下载的两个文件result.txt ，source.txt

       File[] file1 = {new File("result.txt"),new File("source.txt")};

       for(int i=0;i<file1.length;i++) {

           FileInputStream fis = new FileInputStream(file1[i]);

           out.putNextEntry(new ZipEntry(file1[i].getName()));

           int len;

           //读入需要下载的文件的内容，打包到zip文件

          while((len = fis.read(buffer))>0) {

           out.write(buffer,0,len); 

          }

           out.closeEntry();

           fis.close();

       }

        out.close();

        System.out.println("生成Demo.zip成功");

    }

}
