}
//运行测试
public class Test{
public static void main(String[] args) {
EnumDemo spring=new EnumDemo (Season.春);
spring. saySeason ();
EnumDemo summer=new EnumDemo (Season.夏);
summer. saySeason ();
EnumDemo fall=new EnumDemo (Season.秋);
fall. saySeason ();
EnumDemo winter=new EnumDemo (Season.冬);
winter. saySeason ();
}
}

Answer 1

经过测试, 无问题,

import aa.aa;

import aa.aa.Season;

public class test {

 public static void main(String[] args) {

     aa spring=new aa(Season.春);

     spring.saySeason();

     aa summer=new aa(Season.夏);

     summer.saySeason();

     aa fall=new aa(Season.秋);

     fall.saySeason();

     aa winter=new aa(Season.冬);

     winter.saySeason();

 }

}

package aa;

public class aa {

public enum Season{

春,夏,秋,冬

} 

     Season season;

     public aa(Season season) {

         this. season=season;

     }

     public void saySeason () {

         switch (season) {

         case 春:System.out.println("现在是春季.");

         break;

 case 夏:System.out.println("现在是夏季.");

         break;

 case 秋:System.out.println("现在是秋季.");

         break;

 default:System.out.println("现在是冬季。");

         break;

         }

     }

 //运行测试

}

Answer 2

你的代码有多处错误，改成这样就行了。
enum Season {
春, 夏, 秋, 冬
}

public class EnumDemo {
Season season;

public EnumDemo(Season season) {
this.season = season;
}

public void saySeason() {
switch (season) {
case 春:
System.out.println("现在是春季.");
break;
case 夏:
System.out.println("现在是夏季.");
break;
case 秋:
System.out.println("现在是秋季.");
break;
default:
System.out.println("现在是冬季。");
break;
}
}

//运行测试
public static void main(String[] args) {
EnumDemo spring = new EnumDemo(Season.春);
spring.saySeason();
EnumDemo summer = new EnumDemo(Season.夏);
summer.saySeason();
EnumDemo fall = new EnumDemo(Season.秋);
fall.saySeason();
EnumDemo winter = new EnumDemo(Season.冬);
winter.saySeason();
}
}

追问

大神还有一个错误：5：错误：类EnumDemo是公共的，应在名为EnumDemo.java的文件中声明
public class EnumDemo < (class的c下有一个小箭头）

追答

那是因为public 的EnumDemo必须写在同名的java文件里，你把你的测试文件改名为EnumDemo.java就可以了
