This class implements a decoder for decoding byte data using the Base64 encoding scheme as specified in RFC and RFC static class, Base Encodes all bytes from the specified byte array using the Base64 encoding scheme, writing the resulting bytes to the given output byte array, starting at offset 0. With Java 8, Base64 has finally got its due. Java 8 now has inbuilt encoder and decoder for Base64 encoding. In Java 8, we can use three types of Base

How do I decode a Base64 encoded binary?
Encoder class are safe for use by multiple concurrent threads. Unless otherwise noted, passing a null argument to a method of this class will cause a NullPointerException to be thrown.
Encoder withoutPadding Returns an encoder instance that encodes equivalently to this one, but without adding any padding character at the end of the encoded byte data.
The returned byte array is of the length of the resulting bytes. A newly-allocated byte array containing the resulting encoded bytes.
It is the responsibility base64binqry the invoker of this method to make sure the output byte array dst has enough space for encoding all bytes from the input byte array. No bytes will be written to the output byte array if the output byte array is not big enough. The number of bytes written to the output byte array Throws: IllegalArgumentException – if dst does not have enough space jwva encoding all input bytes.
This method first encodes all input bytes base64inary a base64 encoded byte array and then constructs a new String by using the encoded byte array and the ISO charset. In other words, an invocation of this method has exactly the same effect as invoking new String encode srcStandardCharsets.
Upon return, the source buffer’s position will be updated to its limit; its limit will not have been changed. The returned output buffer’s position will be zero and its limit will be the number of resulting encoded bytes. A newly-allocated byte buffer containing the encoded bytes.
Base64 Encoding in Java – Stack Overflow
It is recommended to promptly close the returned output stream after use, during which it will flush all possible leftover bytes to the underlying output stream.
Closing the returned output stream will close the underlying output stream. The encoding scheme of this encoder instance is unaffected by this invocation. The returned encoder instance should be used for non-padding encoding operation.
That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions base64binady terms, workarounds, and working code examples.

Base64 public static class Base Encodes all bytes from the specified byte array using the Base64 encoding scheme, writing the resulting bytes to the given output byte base64binay, starting at offset 0.
Base64 (Java Platform SE 8 )
Encodes all remaining bytes from the specified byte buffer into a newly-allocated ByteBuffer using the Base64 encoding scheme. Encodes the specified byte array into a String using the Base64 encoding scheme.
Returns an encoder instance that encodes equivalently to this one, but without adding any padding character at the end of the encoded byte data. Wraps an output stream for encoding byte data using the Base64 encoding scheme.
