如何重用/重置 ZipInputStream？

我想重置 ZipInputStream （即回到起始位置）以便按顺序读取某些文件。我怎么做？我好卡住...

      ZipEntry entry;
        ZipInputStream input = new ZipInputStream(fileStream);//item.getInputStream());

        int check =0;
        while(check!=2){

          entry = input.getNextEntry();
          if(entry.getName().toString().equals("newFile.csv")){
              check =1;
              InputStreamReader inputStreamReader = new InputStreamReader(input);
                reader = new CSVReader(inputStreamReader);
                //read files
                //reset ZipInputStream if file is read.
                }
                reader.close();
          }
            if(entry.getName().toString().equals("anotherFile.csv")){
              check =2;
              InputStreamReader inputStreamReader = new InputStreamReader(input);
                reader = new CSVReader(inputStreamReader);
                //read files
                //reset ZipInputStream if file is read.
                }
                reader.close();
          }

        }

如果可能（即您有一个实际文件，而不仅仅是要读取的流），请尝试使用ZipFile http://download.oracle.com/javase/1.4.2/docs/api/java/util/zip/ZipFile.html类而不是更底层的 ZipInputStream。 ZipFile 负责在文件中跳转并打开各个条目的流。

ZipFile zip = new ZipFile(filename);
ZipEntry entry = zip.getEntry("newfile.csv");
if (entry != null){
    CSVReader data = new CSVReader(new InputStreamReader(
         zip.getInputStream(entry)));
}
