Java中如何定义枚举类型呢?

定义枚举类型的实现思路

 使用关键字enum
   即可定义枚举类型

// 使用关键字enum定义枚举类型Season
enum Season {
  SPRING, SUMMER, AUTUMN, WINTER
}
 
public class Main {
  public static void main(String[] args) {
    // 使用枚举常量
    Season currentSeason = Season.SPRING;
    System.out.println("Current season: " + currentSeason);
 
    // 遍历枚举常量
    for (Season season : Season.values()) {
      System.out.println(season);
    }
  }
}
