converting String to ASCII--> BASE64

Question

I'm writing a REST client from a C# usage example. Now i need to convert a string in the proper format but can't find the equivalent method on Java.

original:

string Credentials = Convert.ToBase64String(ASCIIEncoding.ASCII.GetBytes(string);

At this point I've done this:

String Credentials = new String(DatatypeConverter.parseBase64Binary(String)); 

but i still need the ASCII conversion and I'm not sure that the things I've fount will work fine, like: Convert character to ASCII numeric value in java

any clues?

Thank you.

If you're using java 8 you should take a look at its new Base64 class. It will provide you with a Base64.Encoder whose encodeToString(byte[] src) method accepts a byte array and return a base64 encoded String.

String base64 = Base64.getEncoder().encodeToString("I'm a String".getBytes());
System.out.println(base64); // prints SSdtIGEgU3RyaW5n
