How to convert string result of enum with overridden toString() back to enum?

Question

Given the following java enum:

public enum AgeRange {

   A18TO23 {
        public String toString() {        
            return \"18 - 23\";
        }
    },
          


        

Answer 1

The best and simplest way to do it is like this:

public enum AgeRange {
    A18TO23 ("18-23"),
    A24TO29 ("24-29"),
    A30TO35("30-35");

    private String value;

    AgeRange(String value){
        this.value = value;
    }

    public String toString(){
        return value;
    }

    public static AgeRange getByValue(String value){
        for (final AgeRange element : EnumSet.allOf(AgeRange.class)) {
            if (element.toString().equals(value)) {
                return element;
            }
        }
        return null;
    }
}

Then you just need to invoke the getByValue() method with the String input in it.
