Writing Java code in blogger posts

I've been looking for a simple way to help me tweak my blog to show Java code.
This is what I've got after some changes in the blog template.

// Comment
public class Testing {
public Testing() {
}

public void Method() {
/* Another Comment
on multiple lines */
int x = 9;
}
}

All you have to do is changing your blog template and add some scripts so you can use the "SyntaxHighlighter" Library.
It works thanks to this post.
