Examples of java.util.zip.GZIPOutputStream.finish()

java.util.zip.GZIPOutputStream.finish()
Finishes writing compressed data to the output stream without closing the underlying stream. Use this method when applying multiple filters in succession to the same output stream. @exception IOException if an I/O error has occurred
