I know this is an old question, but Why isn't this the accepted answer? The whole procedure is then the same as other decoders. The output is mapped to MIME friendly format and represented in lines of no more than 76 characters each, and uses a carriage return '\r' followed by a linefeed '\n' as the line separator. As for decoding the base64 string that we created earlier to be the return image when drawn just by adding .getDecoder() as usual by saving it in byte form, Base-64 encoding converts our binary data into a string containing characters out of 64 printable characters. Here, arr is the input byte array that has to be decoded, and arr2 is the output array. Java 8 Base64 Methods Base64 is a base class for encoding and decoding. First, import it as you normally do: Then use the Base64 static methods as follow: If not using Java8, you need to import Base64 from external library.2 Base64.encodeBase64() & Base64.decodeBase64() Example: UseisChunked argument and pass it as true then it will divide the encoded string into multiple lines and each line with 76 characters. Source: . Use the below methods to get the right encoders and decoders for each type. The main advantage of encoding and decoding these data is its privacy as well as security.
