Favorite IDE Spring Tool Suite (STS), Eclipse IDE or NetBeans (I happen to be using STS because it comes with a Tomcat server built-in).In order to run this tutorial yourself, you will need the following: Base64 Encoding/Decoding Google Guava Output.Base64 Encoding/Decoding using Google Guava Library.Base64 Alphabet Characters Used for Encoding.Please review our Java 8 tutorial called “Base64 Encoding and Decoding Examples in Java 8”. If you are using Java 8, you may be aware that it now natively supports Base64 encoding and decoding.

In our other tutorials, we discuss how to perform “Base64 Encoding and Decoding Examples in Java using Apache Commons”. In this tutorial we will discuss how to Encode and Decode using Base64 using Google’s Guava Project Open Source library. Parameters: buffer - the source ByteBuffer to encode Returns: A newly-allocated byte buffer containing the encoded bytes.Base64 Encoding and Decoding Examples in Java using Google Guava The returned output buffer's position will be zero and its limit will be the number of resulting encoded bytes. Upon return, the source buffer's position will be updated to its limit its limit will not have been changed. Parameters: src - the byte array to encode Returns: A String containing the resulting Base64 encoded characters encode public ByteBuffer encode(ByteBuffer buffer)Įncodes all remaining bytes from the specified byte buffer into a newly-allocated ByteBuffer using the Base64 encoding scheme. In other words, an invocation of this method has exactly the same effect as invoking new String(encode(src), StandardCharsets.ISO_8859_1). This method first encodes all input bytes into a base64 encoded byte array and then constructs a new String by using the encoded byte array and the ISO-8859-1 charset. Object clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait Wraps an output stream for encoding byte data 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. Since: 1.8 See Also: Base64.Decoder Method Summary All Methods Instance Methods Concrete Methods Modifier and TypeĮncodes all bytes from the specified byte array into a newly-allocated byte array using the Base64 encoding scheme.Įncodes 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.Įncodes all remaining bytes from the specified byte buffer into a newly-allocated ByteBuffer using the Base64 encoding scheme.Įncodes the specified byte array into a String using the Base64 encoding scheme. Unless otherwise noted, passing a null argument to a method of this class will cause a NullPointerException to be thrown.
Instances of Base64.Encoder class are safe for use by multiple concurrent threads. This class implements an encoder for encoding byte data using the Base64 encoding scheme as specified in RFC 4648 and RFC 2045.
