Abstract class with all concrete methods

Question

Are there some practical programming situations for someone to declare a class abstract when all the methods in it are concrete?

Answer 1

Nice question :)

One thing is for sure ... this is certainly possible. The template suggestion by krosenvold is one good reason for doing this.

I just want to say that a class must not be declared abstract just for preventing it's instantiation.

This is referred in the Java Language Specification Section 8.1.1.1
