Google "java enum" and the first hit is the Java tutorials section on enums, which contains a couple of examples.

The type-safety is the main reason, but because of they way enums are implemented in Java (enums are just specialised classes) they have some other convenient features.
It is sorta covered in the JavaRanch Style Guide.
