java - 枚举和开关帮助。 Java学习者

Question

我是一名Java自学者，被这个问题困扰了。尝试过不合理的组合和可能的解决方案，但遇到了更多的错误。

public class SeasonsSwitch {
    enum Season  {
            WINTER,
            SPRING,
            SUMMER,
            FALL
        }
    public static void main(String[] args){

        String currentSeason;
        currentSeason = TextIO.getWord();
        switch (currentSeason){
            case WINTER:
            TextIO.put("Decemeber, January, February");
            break;
            case SPRING:
            TextIO.put("March, April, May");
            break;
            case SUMMER:
            TextIO.put("June, July, August");
            break;
            case FALL:
            TextIO.put("September, October, November");

        }

    }
}

使用Season.valueOf将枚举常量的字符串表示形式转换为枚举常量。

Season s = Season.valueOf(currentSeason);
switch (s){

Enum.valueOf tutorial

The java.lang.Enum.valueOf() method returns the enum constant of the specified enumtype with the specified name. The name must match exactly an identifier used to declare an enum constant in this type.
