Using BASE64 in Java

Question

Problem:

---

I can’t import the classes BASE64Decoder and BASE64Encoder, there are N code that use them and when I use them everything that is related does not work precisely because they are not found.

---

import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;

I need to understand why I can’t find the package sun.misc and to classes BASE64Decoder and BASE64Encoder. Who can help?

Since Java 6, you can use static methods printBase64Binary and parseBase64Binary class DatatypeConverter.

Take an example:

String base64 = DatatypeConverter.printBase64Binary("Blá = 1".getBytes("UTF-8"));
System.out.println(base64);

String original = new String(DatatypeConverter.parseBase64Binary(base64), "UTF-8");
System.out.println(original);

This will print:

Blah = 1
