        String orig = "original String before base64 encoding in Java";

        //encoding  byte array into base 64

        byte[] encoded = Base64.encodeBase64(orig.getBytes());     

      

        System.out.println("Original String: " + orig );

        System.out.println("Base64 Encoded String : " + new String(encoded));

      

        //decoding byte array into base64

        byte[] decoded = Base64.decodeBase64(encoded);      

        System.out.println("Base 64 Decoded  String : " + new String(decoded));
