Base64 in Java: java.util.Base64 Complete Reference Java's API landed in Java 8 and replaced the hodgepodge of third-party libraries and internal classes that existed before. It offers three variants (standard, URL-safe, and MIME), both stream and non-stream interfaces, and a clean, composable encoder/decoder design. This guide covers every method you'll realistically use. --- The three variants exposes three static factory methods, each returning a variant configured for a specific use case: | Method | Alphabet | Padding | Line breaks | |---|---|---|---| | | | Yes () | No | | | | Yes () | No | | | | Yes () | Yes (76 chars, ) | Correspondingly: | Method | Use | |---|---| | | Decodes standard Base64 | | | Decodes URL-safe Base64 | | | Decodes MIME Base64 (ignores and whitespace) | ---…
