Its a static method in SimpleTagSupport class.

You must have read the JavaDocs for this method.

For understanding how it works, here is the source code from Tomcat implementation:


Read the code above, its pretty straightforward to see how it has been implemented (see the for loop above).

I think now you can write an example yourself. Isn't it?
 
It is sorta covered in the JavaRanch Style Guide.
