閱讀目錄內容而不是zip文件內容

Question

我有這段代碼，它使我能夠讀取zip文件的內容，但我希望讀取目錄內容而不是zip文件（zip文件必須看作是目錄）。我該怎麼辦 ？

import java.util.HashMap; 
import java.util.Map; 
import java.util.zip.ZipEntry; 
import java.util.zip.ZipFile; 

public class ZipFileDataReader { 
    private ZipFile zipFile; 
    private Map zipEntry2dataReader; 

    public ZipFileDataReader(ZipFile zipFile) { 
     this.zipFile = zipFile; 
     zipEntry2dataReader = new HashMap(); 
    } 

    public synchronized ZipEntryDataReader getZipEntryDataReader(
      ZipEntry zipEntry, long offset, int size) { 
     ZipEntryDataReader entryReader = (ZipEntryDataReader) zipEntry2dataReader 
       .get(zipEntry.getName()); 

     if (entryReader == null) { 
      entryReader = new ZipEntryDataReader(zipFile, zipEntry); 
      zipEntry2dataReader.put(zipEntry.getName(), entryReader); 
     } 

     return entryReader; 
    } 

    public synchronized void releaseZipEntryDataReader(ZipEntry zipEntry) { 
     zipEntry2dataReader.remove(zipEntry.getName()); 
    } 
}
