  import java.io.File;

  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");

  }
