Method Details- 
closeWrites any remaining uncompressed data to the output stream and closes the underlying output stream.- Specified by:
- closein interface- AutoCloseable
- Specified by:
- closein interface- Closeable
- Overrides:
- closein class- FilterOutputStream
- Throws:
- IOException- if an I/O error occurs
- See Also:
 
- 
flushFlushes this output stream, forcing any pending buffered output bytes to be written.- Specified by:
- flushin interface- Flushable
- Overrides:
- flushin class- FilterOutputStream
- Throws:
- IOException- if an I/O error occurs or this stream is already closed
- See Also:
 
- 
finishFinishes writing uncompressed data to the output stream without closing the underlying stream. Use this method when applying multiple filters in succession to the same output stream.- Throws:
- IOException- if an I/O error occurs or this stream is already closed
 
- 
writeWrites a byte to the uncompressed output stream.- Overrides:
- writein class- FilterOutputStream
- Parameters:
- b- a single byte of compressed data to decompress and write to the output stream
- Throws:
- IOException- if an I/O error occurs or this stream is already closed
- ZipException- if a compression (ZIP) format error occurs
 
- 
writeWrites an array of bytes to the uncompressed output stream.- Overrides:
- writein class- FilterOutputStream
- Parameters:
- b- buffer containing compressed data to decompress and write to the output stream
- off- starting offset of the compressed data within- b
- len- number of bytes to decompress from- b
- Throws:
- IndexOutOfBoundsException- if- off < 0, or if- len < 0, or if- len > b.length - off
- IOException- if an I/O error occurs or this stream is already closed
- NullPointerException- if- bis null
- ZipException- if a compression (ZIP) format error occurs
