I have 3 String arrays with constants. eg:

 String[] digit = {"one", "two", "three"};
 String[] teen= {"ten", "twenty", "thirty"};
 String[] anchors = {"hundred", "thousand", "million"};

I'm thinking of transferring these to enums separately, so I will have 3 enum classes: digit, teen and anchors with getValue methods implemented. But I don't want to have them in separate files as I have only small data and same type of data. What is the best way to have all these with access methods in same meaningful java file?

• java
• arrays
• enums
• constants

They can be three inner classes like this:

public class Types {
  public enum Digits {...}
  public enum Teens {...}
  ....
}

Then refer them Types.Digits.ONE, Types.Teen.TWENTY etc.

You can also use static imports like this:

import Types.Digits;
import Types.Teen;

..

in order to have shorter references: Digits.ONE, Teen.TWENTY etc.
