Question

Given the following java enum:

public enum AgeRange {     A18TO23 {         public String toString() {                     return '18 - 23';         }     },    A24TO29 {         public String toString() {                     return '24 - 29';         }     },    A30TO35 {         public String toString() {                     return '30 - 35';         }     },  } 

Is there any way to convert a string value of ’18 – 23′ to the corresponding enum value i.e. AgeRange.A18TO23 ?

Thanks!

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.
