Java equals()

I want to put an equals() method in all of mine immutable (final) classes.
Should I use the instanceof or the getClass() approach?

thanks!

This might surprise you but javas "primitive" integers exhibit intelligent autoboxing behaviour, in fact. A primitive integer could even be considered a wrapper around its Integer object that simply hides all the details until neccesary- what better effeciency could you ask for? On the subject of effeciency, java arithmetic is actually benchmarkedly faster than Se and Sepples arithmetic, a testament to the sound design decisions of the Sun Java team.
