    public static String encodeBase64(byte[] bytes) throws Exception {

        return base64Encoder.encodeBuffer(bytes).replace("\r\n", "").replace("\n", "");

    }

    public static void println(Object o) {
        System.out.println("" + o);
    }
}

Output would be like this...

Original_String_Length=1000
Compressed_String_Length=824, Compression_Ratio=17.600%
Decompressed_String_Length=1000 == Original_String_Length (1000)
Original_String == Decompressed_String=True

** More big string more compression ratio
** More similar words more compression ratio
