Java.util.zip.GZIPInputStream klasa u Javi

Ova klasa implementira filter toka za čitanje komprimiranih podataka u GZIP formatu datoteke. Konstruktori
    GZIPInputStream(InputStream in) :Stvara novi ulazni tok sa zadanom veličinom međuspremnika. GZIPInputStream(InputStream u int veličini) :Stvara novi ulazni tok s navedenom veličinom međuspremnika.
metode:
    void close() : Closes this input stream and releases any system resources associated with the stream.
      Syntax :  public void close() throws IOException   Specified by:   close in interface Closeable   Specified by:   close in interface AutoCloseable   Overrides:   close in class InflaterInputStream   Throws:   IOException 
    int read(byte[] buf int off int len) : Reads uncompressed data into an array of bytes. If len is not zero the method will block until some input can be decompressed; otherwise no bytes are read and 0 is returned.
      Syntax :  public int read(byte[] buf int off int len) throws IOException   Overrides:   read in class InflaterInputStream   Parameters:   buf - the buffer into which the data is read off - the start offset in the destination array b len - the maximum number of bytes read   Returns:   the actual number of bytes read or -1 if the end of the compressed input stream is reached   Throws:   NullPointerException IndexOutOfBoundsException ZipException IOException
