使用name() 方法能够把Java Enum转换为String 代码语言:javascript 代码运行次数:0 运行 AI代码解释 publicclassVehicleTest{publicstaticvoidmain(String[]args){System.out.println(Vehicle.BIKE.name());System.out.println(Vehicle.BUS.name());System.out.println(Vehicle.CAR.name());System.out.println(Vehicle...
使用name()方法能够获得Enum的名称,name()方法是枚举类内置的方法。 三、使用toString()方法转换为String 像大多数的对象一样,默认都会有一个toString()方法,枚举也不例外 publicclassVehicleTest{publicstaticvoidmain(String[] args){ System.out.println(Vehicle.BIKE.toString()); System.out.println(Vehicle...
privateGender(String name,int original){super(name,original)}publicstaticGender[]values(){return$VALUE.clone();}publicstaticGendervalueOf(String name){returnEnum.valueOf(Gender.class,name);}} 创建的枚举类型默认是java.lang.enum<枚举类型名>(抽象类)的子类 每个枚举项的类型都为public static final 。

Enum() Initializes a new instance of the Enum class. Methods Expand table CompareTo(Object) Compares this instance to a specified object and returns an indication of their relative values. Equals(Object) Returns a value indicating whether this instance is equal to a specified object. Forma...
String 一个格式字符串。 返回 String 此实例的值的字符串表示形式,由format指定。 例外 FormatException format包含无效的规范。 InvalidOperationException format等于“X”,但枚举类型未知。 示例 以下示例演示如何将枚举值转换为字符串。 C# // Sample for Enum.ToString(String)usingSystem;classSample{enumColors {...
int compareTo(E o) 对象比较 boolean equals(Object obj) 比较两个枚举对象 String name() 返回此枚举的名称 int ordinal() 返回枚举常量的序数 *下面定义一个枚举类 1 public class GetEnumContent 2 { 3 public enum Color 4 { 5 RED,GREEN,BLUE; ...
The biggest limitation is that theBETTER_ENUMmacro can't be used inside a class. This seemsdifficult to remove. There is a workaround withtypedef(or C++11using): BETTER_ENUM(SomePrefix_Color,uint8_t, Red, Green, Blue)structtriplet{typedefSomePrefix_Color Color; ...

具体的测试代码: 基于vsim的测试结果如下: string到enum的转换常见于验证环境解析配置或者数据文件,遇到字符串后,需要判断该字符串所属于的enum元素。 注:enum_for的实现方式参考了sv_lib的内容,并做了相关的删减和改进。
