Question

Suppose I have a number of fields (String or int) in my Java enum, and I want to get a field value by its name , dynamically.

public enum Code {

    FIRST("valueForFirst"),
    SECOND("valueForSecond");
    // etc
}

Then I get the name of the field which I want:

String fieldName = getEnumFieldName(); // can be: "FIRST" or "SECOND" 
// now get "fieldName"'s value from Code

How can I do this ?

Answer 1

You need to use Enum.valueOf(); such as:

Code c = Code.valueOf(Code.class, fieldName);
