Note Item:1. Using enumerations in switch can make your code more readable. 2. If you want to customize a method, you must add a semicolon at the end of the enum instance sequence.And Java requires that an enum instance be defined first.3. All enumerations inherit from the Java.lang.Enum class, and because

JDK1.5 introduces a new type--enumeration. In Java, although it is a "small" function, but to my development has brought "big" convenience.Usage One: constant.Before JDK1.5, we defined constants: public static fianl ..... Now, with enumerations, you can group related constants into an enumeration type, and enumerations provide more methods than constants. Public enum Color { RED, GREEN, BLANK, YELLOW}Si
