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
