Diese Klasse verfügt über mehrere verschachtelte Klassen wie Encoder und Decoder, die zum Kodieren und Dekodieren von Daten verwendet werden können. Java hat in seiner Java 8-Version eine neue Klasse, Base64, hinzugefügt. The decoder ignores all line separators or other characters not found in the basic base64 alphabet. Dieses Tutorial stellt vor, was code in Java ist und wie man es verwendet, um die kodierten Daten in Java zu dekodieren. ![]() Each line (except the last line) is separated from the next line via a carriage return ( \r) followed by a linefeed ( \n). The encoded output is organized into lines of no more than 76 characters. This class provides several methods for decoding Base64 to byte data. MIME: The MIME variant uses the Basic Base64 alphabet which contains characters from the set A-Z, a-z, 0-9, + and /. Since Java 1.8 developers can use the Base64.Decoder class to decode Base64 values. Decoding a previously Base64 encoded string we perform the identical steps as we did in the encoding phase. Uses 'The Base64 Alphabet' as specified in Table 1 of RFC 4648 and RFC 2045 for encoding and decoding. The implementation of this class supports the following types of Base64 as specified in RFC 4648 and RFC 2045. The decoder rejects data that contains characters outside A-Za-z0-9-_ This class consists exclusively of static methods for obtaining encoders and decoders for the Base64 encoding scheme. URL and Filename Safe: It is same as the Basic Base64 encoding except that + is replaced by - and / is replaced by _ to make the output URL and filename safe. The decoder rejects data that contains characters outside this set. The output contains characters from the set A-Z, a-z, 0-9, + and /. The Java 8 Base64 API supports three different variants of Base64 encoding as described in RFC 4648 and RFC 2045.īasic: This is the standard Base64 encoding defined in RFC 4648. The following program uses () method for encoding the specified byte array into a Base64 encoded string and (). In this article, you’ll learn how to Base64 encode any arbitrary text in Java using the Base64 API that was introduced in Java 8. ![]() These source code samples are taken from different open source. Base64 is a binary-to-text encoding scheme that represents binary data in a printable ASCII string format. This java examples will help you to understand the usage of.
