Method

booleanisGzip(byte[] bytes)
is Gzip 
return (bytes != null && bytes.length > 2 && bytes[0] == (byte) 0x1F && bytes[1] == (byte) 0x8B);
booleanisGZipped(byte[] bytes)
is G Zipped 
if ((bytes == null) || (bytes.length < 2)) {
    return false;
} else {
    return ((bytes[0] == (byte) (GZIPInputStream.GZIP_MAGIC))
            && (bytes[1] == (byte) (GZIPInputStream.GZIP_MAGIC >> 8)));
booleanisGzipped(byte[] data)
Determines if the data contained in the buffer is gzipped by matching the first 2 bytes with GZIP magic GZIP_MAGIC (0x8b1f). 
if (data == null || data.length < 2) {
    return false;
int byte1 = data[0];
int byte2 = data[1] & 0xff; 
return (byte1 | (byte2 << 8)) == GZIPInputStream.GZIP_MAGIC;
