java 枚举 示例

## 枚举类name()方法 **(**Enum Class name() method**)** ##

*  **name() method** is available in java.lang package.
    
    **name()方法**在java.lang包中可用。
 *  **name() method** is used to return the name of this enum constants as it is declared in its enum prototype or declaration.
    
    **name()方法**用于返回此枚举常量的名称，该名称在其枚举原型或声明中进行了声明。
 *  **name() method** is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
    
    **name()方法**是一个非静态方法，只能通过类对象访问，如果尝试使用类名称访问该方法，则会收到错误消息。
 *  **name() method** is a final method, it does not override in child class.
    
    **name()方法**是最终方法，它不会在子类中重写。
 *  **name() method** does not throw an exception at the time of returning the name of the enum constants.
    
    返回枚举常量名称时， **name()方法**不会引发异常。

// Java program to demonstrate the example 
    // of String name() of Enum method
    
    enum Month {

            Month m2 = Month.FEB;
            Month m3 = Month.MAR;
            Month m4 = Month.APR;
            Month m5 = Month.MAY;
    
            System.out.println("Display Name: ");
            // By using name() method is to get the enum
            // constant name 
            System.out.println("m1.name() " + " " + m1.name());
            System.out.println("m2.name()" + " " + m2.name());
            System.out.println("m3.name()" + " " + m3.name());
            System.out.println("m4.name()" + " " + m4.name());
