You should replace your getEnumNameForValue by a call to the name   method

In such cases  you can convert the values of enum to a List and stream through it   Something like below examples  I would recommend using filter     Using ForEach   List lt Category gt  category   Arrays asList Category values     category stream   forEach eachCategory - gt                if eachCategory toString   equals  3                     String name   eachCategory name                                Or  using Filter   When you want to find with code   List lt Category gt  categoryList   Arrays asList Category values     Category category   categoryList stream   filter eachCategory - gt  eachCategory toString   equals  3    findAny   orElse null    System out println category toString           category name       When you want to find with name   List lt Category gt  categoryList   Arrays asList Category values     Category category   categoryList stream   filter eachCategory - gt  eachCategory name   equals  Apple    findAny   orElse null    System out println category toString           category name       Hope it helps  I know this is a very old post  but someone can get help

Here is the below code  it will return the Enum name from Enum value   public enum Test        PLUS  Plus One    MINUS  MinusTwo    TIMES  MultiplyByFour    DIVIDE               DivideByZero        private String operationName       private Test final String operationName            setOperationName operationName              public String getOperationName             return operationName             public void setOperationName final String operationName            this operationName   operationName             public static Test getOperationName final String operationName             for  Test oprname   Test values                  if  operationName equals oprname toString                       return oprname                                  return null              Override     public String toString             return operationName           public class Main       public static void main String   args             Test test   Test getOperationName  Plus One            switch  test            case PLUS              System out println  Plus                     break          case MINUS              System out println  Minus                     break           default              System out println  Nothing                  break
