Java枚举类配合Switch

开发中常常使用枚举类配合switch,省去繁琐if判断

public enum FruitType {

    
    apple("1", "Apple"),

    
    orage("2", "ORANGE"),

    
    banana("3", "BANANA");

    String code;
    String name;

    CourseBuyType(String code, String name) {
        this.code = code;
        this.name = name;
    }

    //根据枚举类的 code 值，获取枚举类型
    public static FruitType getEnumByKey(String key) {
        for (FruitType fruitType : FruitType.values()) {
            if (key.equals(fruitType.code)) {
                return fruitType;
            }
        }
        return null;
    }

    //根据code值，获取当前枚举类的name
    public static String getValueByKey(String key) {
        for (FruitType fruitType : FruitType.values()) {
            if (key.equals(FruitType.code)) {
                return FruitType.name;
            }
        }
        return null;
    }

}

switch (FruitType.getEnumByKey("1")) {
            
            case apple:
                //苹果业务逻辑
                //.....
                break;
            case orage:
                //橘子业务逻辑
                //......
                break;
            case banana:
                //香蕉业务逻辑
                //......
                break;
        }
    }
