Base64 Encoding With JDK 1.6+ And Java 8

The method: javax.xml.bind.DatatypeConverter#printBase64Binary(byte[]) encodes a byte[] into a Base64 encoded string.

To encode a String with JDK 1.6+ use the static method printBase64Binary:


String encodedDuke = DatatypeConverter.printBase64Binary("duke".getBytes("UTF-8"));

Java 8 comes with the java.util.Base64 class entirely dedicated to Basic, URL, Filenames and MIMEs encoding and decoding.

Hello Adam, thank you.
Few days ago before your post i removed Bouncy Castle provider from project which was used for converting data to base64 and back.
Also DatatypeConverter class contains many helpful methods not only for base64 coding/encoding.

I'm not a developer, i always use the free online base64 string converter(http://www.online-code.net/base64-string.html) to encode and decode base64.
