Method Detail- 
closepublic void close() throws IOExceptionWrites 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:
- FilterOutputStream.flush(),- FilterOutputStream.out
 
 - 
flushpublic void flush() throws IOExceptionFlushes 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:
- FilterOutputStream.out
 
 - 
finishpublic void finish() throws IOExceptionFinishes 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
 
 - 
writepublic void write(int b) throws IOExceptionWrites 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
 
 - 
writepublic void write(byte[] b, int off, int len) throws IOExceptionWrites 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

- FilterOutputStream.write(int)
