Java Interface, AbstractClass and Enum naming convention

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.
