Java中枚举的toString()和name()区别小结

// 定义一个表示季节的枚举
enum Season {
    SPRING,
    SUMMER,
    AUTUMN,
    WINTER;

    // 重写 toString() 方法，让其返回更具描述性的字符串
    @Override
    public String toString() {
        switch (this) {
            case SPRING:
                return "春季";
            case SUMMER:
                return "夏季";
            case AUTUMN:
                return "秋季";
            case WINTER:
                return "冬季";
            default:
                return super.toString();
        }
    }
}

        // 使用 toString() 方法获取枚举常量的字符串表示
        System.out.println("toString() 方法返回: " + season.toString());
