How to enhance an enumeration and work with static imports

• All enumerations inherit the java.lang.Object and java.lang.Enum classes. They can use or override the methods of those classes or add new methods.
• By default, the toString method of an enumeration constant returns the same string as the name method.
• You can use a static import to import all of the constants of an enumeration or all of the static fields and methods of a class.
• When you use a static import, you don't need to qualify the constant, field, or method with the name of the enumeration or class.
