Java Whirlpool hashing

Question

I found myself in the need to hash something in Java and as I don't understand hashing I'm here.

I already found that there's no simple method for it.

So my question: how is whirlpool hashing done in Java?

EDIT: I was suggested GNU Whirlpool, but I can't get it to work

            Whirlpool wp = new Whirlpool();

            String s = "The quick brown fox jumps over the lazy dog";
            byte[] b = s.getBytes(Charset.forName("UTF-8"));
            wp.update(b, 0, s.length());
            byte[] r = wp.digest();

            String str = new String(r,Charset.forName("UTF-8"));
            System.out.println(str);

And the output is: <?R??XF ????n?g?Tl??H?po??????? m? 5?F ?? y?QhTM?|?I??? Am I missing something? Or did I not understand how it works?

Solve: It seems the digest method outputs raw byte data. I converted it to HEX format using a method from Apache common codec library.

Use GNU Whirlpool. This is a java implementation of Whirlpool from GNU.
