```
public ZipInputStream(InputStream in)
```
    Creates a new ZIP input stream.
    The UTF-8 charset is used to decode the entry names.
    
    参数:
    
    in - the actual input stream
  - ZipInputStream
```
public ZipInputStream(InputStream in,
                      Charset charset)
```
    Creates a new ZIP input stream.
    
    参数:
    
    in - the actual input stream
    
    charset - The charset to be used to decode the ZIP entry name (ignored if the language encoding bit of the ZIP entry's general purpose bit flag is set).

  - getNextEntry
```
public ZipEntry getNextEntry()
                      throws IOException
```
    Reads the next ZIP file entry and positions the stream at the beginning of the entry data.
    
    返回:
    
    the next ZIP file entry, or null if there are no more entries
    
    抛出:
    
    ZipException - if a ZIP file error has occurred
    
    IOException - if an I/O error has occurred
  - closeEntry
```
public void closeEntry()
                throws IOException
```
    Closes the current ZIP entry and positions the stream for reading the next entry.
    
    抛出:
    
    ZipException - if a ZIP file error has occurred
    
    IOException - if an I/O error has occurred
  - available
```
