Question

We are having this discussion in our team about code conventions for Java for:

• interface: Foo or IFoo or FooInterface?

• abstract: Foo or AbstractFoo?

• Enums: Foo or FooEnum?

I’m basically trying to put my personal preferences aside 🙂 so reasons to back up one or other convention are very welcome.

Answer 1

In Java: Foo, AbstractFoo and Foo – although AbstractFoo could just be Foo.

Evidence:

• java.util.List (interface)
• java.util.AbstractList (abstract class)
• java.util.Formatter.BigDecimalLayoutForm (enum)

For the interface part, see the Naming Conventions section of the Java Coding Conventions document. It doesn’t talk about enums and abstract classes though.
