java 枚举 找不到符号

Posted 2023-04-01

public class EnumWithMethods

public enum Season
SPRING,SUMMER,FALL,WINTER;
private final static String location="Phoenix";
public static Season getBest()

if(location.equals("Phoenix"))
return WINTER;
else
return SUMMER;

public static void main(String args[])

System.out.println(Season.getBest());


书上的程序，显示了3个错误，都是找不到符号，分别是WINTER,SUMMER,getBest方法，麻烦高手解释下

public class EnumWithMethods

public enum Season

SPRING, SUMMER, FALL, WINTER
;
private final static String location = "Phoenix";

public static Season getBest()
if (location.equals("Phoenix"))
return Season.WINTER;//
else
return Season.SUMMER;//



public static void main(String args[])
System.out.println(EnumWithMethods.getBest());//



说明：1、WINTER、SUMMER是Season中定义的要改为：Season.WINTER、Season.SUMMER；
2、getBest（）函数定义为public static 类型的，你在本类（EnumWithMethods而非Season）中可直接调用写成System.out.println(getBest());，或加上类名的System.out.println(EnumWithMethods.getBest()); 参考技术A public class EnumWithMethods
public enum Season
SPRING,SUMMER,FALL,WINTER;
private final static String location="Phoenix";
public static Season getBest()

if(location.equals("Phoenix"))
return Season.WINTER;
else
return Season.SUMMER;


public static void main(String args[])

System.out.println(getBest());


参考技术B public enum Season
SPRING,SUMMER,FALL,WINTER;
多了一个；号。把那个去掉。
