Java how to access inner enum class

Question

public class Constant {    ......    public enum Status {     ERROR,     WARNING,     NORMAL   }    ......  } 

After compiling I got a class file named Constant$Status.class. The question is, how can I access the enum value. For instance, I want to get the string representation of the ERROR status.

Answer 1

You'll be able to access it elsewhere like

import package.name.Constant; //... Constant.Status foo = Constant.Status.ERROR; 

or,

import package.name.Constant; import package.name.Constant.Status; //... Status foo = Status.ERROR;

To get the declared name of any enum element, use Enum#name():

Status foo = ...; String fooName = foo.name();
