title: java ZipOutputStream problem
body: <p>I am trying to write a java ZIP util class as below:</p>
  
  <pre><code>package fdbank.util;
  
  import java.io.File;
  import java.io.FileInputStream;
  import java.io.FileOutputStream;
  import java.io.IOException;
  import java.util.zip.ZipEntry;
  import java.util.zip.ZipOutputStream;
  
  /**

  public class ZIPUtil {
  
      private static void zip(File[] files, String dest) throws IOException{
          ZipOutputStream zos = new ZipOutputStream(new FileOutputStream(new File("dest")));
          for(File file : files){
              zip(file, zos);
          }
          zos.close();
      }
  
      private static void zip(File file, ZipOutputStream zos) throws IOException{
          byte[] buf = new byte[2048];
          @SuppressWarnings("unused")
          int bytes = 0;
          if(file.isDirectory()){
              ZipEntry entry = new ZipEntry(file.getName());
              zos.putNextEntry(entry);
              for(File subFile : file.listFiles()){
                  zip(subFile, zos);
              }
              zos.closeEntry();
          }
          FileInputStream fis = new FileInputStream(file);
          System.out.println(file.getName());
          ZipEntry entry = new ZipEntry(file.getName());
          zos.putNextEntry(entry);
          while((bytes = fis.read(buf)) != -1){
              zos.write(buf);
          }
          zos.closeEntry();
          fis.close();
      }
  
  
  
      public static void compress(int archiveType, File[] files, String dest){
  
      }
  
      public static void main(String[] args){
          try {
              System.out.println("gan !!!!");
              zip(new File[]{new File("F:\\ziptest\\1.bmp")},"c:\\ziptest.zip");
          } catch (IOException e) {
              e.printStackTrace();
          }
      }
  }
