In this guide to Java enum with string values, learn to create enum using strings, iterate over all enum values, get enum value and to perform reverse lookup to find enum by string parameter. In thisguide to Javaenumwith string values, learn tocreate enum using strings, iterate over all e...
In the above code, we’ve created a methodprintDayValue()that takes an enum constant as a parameter and prints the constant along with its value. These examples showcase the versatility of enums with values in Java, and how they can be used in various scenarios to make your code more e...

You can use the valueOf() method to convert a string to an enum value in Java. The valueOf() method takes a string as an argument and returns the corresponding enum object. Let us say we have the following enum class that represents the days of the week: public enum Day { MONDAY, ...

枚举类型是 Java 5 中增加的一个小特性,在此之前,实现枚举的方式为定义编译期常量形式。而代码中使用编译期常量的方式在理解性和安全性方面存在不足,单纯的常量数值不能够直观的体现出其作为枚举实例的目的,且实际中无限的取值空间也不能很好的与理论上有限的枚举空间相
