Anyone using short and byte primitive types, in real apps?

Question

I have been programming in Java since 2004, mostly enterprise and web applications. But I have never used short or byte, other than a toy program just to know

Answer 1

It's perhaps more interesting to look at the semantics of int. Are those arbitrary limits and silent truncation what you want? For application-level code really wants arbitrary sized integers, it's just that Java has no way of expressing those reasonably.

Answer 2

Keep in mind that Java is also used on mobile devices, where memory is much more limited.

Answer 3

bytes and shorts are extensively used in Java Card development. Take a look at my answer to Are there any real life uses for the Java byte primitive type?.
