将整数值转换为匹配的Java Enum

public enum MyEnum {
    VALUE1,
    VALUE2,
    VALUE3
}

public static MyEnum convertToEnum(int value) {
    switch (value) {
        case 1:
            return MyEnum.VALUE1;
        case 2:
            return MyEnum.VALUE2;
        case 3:
            return MyEnum.VALUE3;
        default:
            throw new IllegalArgumentException("Invalid value: " + value);
    }
}

int intValue = 2;
MyEnum enumValue = convertToEnum(intValue);
System.out.println(enumValue); // 输出 VALUE2
