[java]枚举类练习

emm...很

想法：

  1. 枚举类实现季节信息打印
  2. 一个简单的交互
  3. 一个很艹的剧情

上代码

enum Season

package com.wenjun.www;  public enum Season {     SPRING(温暖,三月),SUMMER(炎热,六月),AUTUMN(凉爽,八月),WINTER(寒冷,十二月);     @SuppressWarnings(all)     private String intro = ;     @SuppressWarnings(all)     private String month = ;     Test(String intro, String mouth) {         this.intro = intro;         this.mouth = month;     }      @Override     public String toString() {         return this.name().toLowerCase()+ 在+month+最+intro;     } }

对吧，直接重写toString()打印完事。不要在意@SuppressWarnings(all)[滑稽]

class mainMenu

package com.wenjun.www;  import com.wenjun.www.Season;  import java.util.Scanner;  public class mainMenu {     private boolean appear = true;     private Scanner choice = new Scanner(System.in);     private String seasonName = ;     private Season[] seasons = Season.values();     private void seasonList(){         for (Season value : seasons) {             System.out.println(value);         }     }     public void menu(){         do {             System.out.println(燕子，你喜欢哪个季节？);             seasonList();             System.out.println(选一个,不行让我滚！);             season_name = choice.next();             switch (seasonName){                 case spring:                     findSeason(0);                     break;                 case summer:                     findSeason(1);                     break;                 case autumn:                     findSeason(2);                     break;                 case winter:                     findSeason(3);                     break;                 case 滚:                     System.out.println(燕子！你别走啊燕子！);                     System.out.println(司机：“确定要加速吗？”（y/n）:);                     seasonName = choice.next();                     if (seasonName.toUpperCase().equals(Y)){                         appear = false;                     }                     break;                 default:                     System.out.println(燕子！你说句话啊燕子！);                     break;             }         }while (appear);     }      private void findSeason(int id){         System.out.println(seasons[id]);     } }
  1. Season[] seasons = Season.values();直接全装进去
  2. seasonList()增强for循环打印
  3. menu()中switch+Scanner简单交互
  4. findSeason()数组下标查询打印
  5. 生草的剧情

RUN!

package com.wenjun.www;   import com.wenjun.www.mainMenu;  public class App {     public static void main(String[] args) {         new mainMenu().menu();         System.out.println(燕子！！！);     }  }

完事！
