java语言基础--枚举

关键字：enum

public class Main {

    public enum Season{
        Spring,Summer,Autumn,Winter;
    }
    
    public static void main(String[] args) {
        Season spring = Season.Spring;
        System.out.println(spring);
    }
}

自定义常量类

和枚举是一样的，这个开发过程中用到的多

public class Main2 {

    public final static String  SPRING ="Spring";
    public final static String SUMMER = "Summer";
    public final static String ATUMN ="Atumn";
    public final static String WINTER = "Winter";
}
