Get index of enum from string?

I have a string value, I also have an array of strings and an enum containing the range also. To get the index of the string in the array, from the value supplied I write this:

Arrays.asList(myClass.BAUD_RATES).indexOf(username)

How do I do this for an enum? Can I use ordinal? Or do i have to make my own method?

The method might go like:

public enum Fruit {
   ...
   static public boolean isMember(String aName) {
       Fruit[] aFruits = Fruit.values();
       for (Fruit aFruit : aFruits)
           if (aFruit.fruitname.equals(aName))
               return aFruit;
       return false;
   }
   ...
}

Answer

Not sure if I understand you correctly but based on question title you may be looking for

YourEnum.valueOf("VALUE").ordinal();

1. YourEnum.valueOf("VALUE") returns enum value with name "VALUE"
2. each enum value knows its position (indexed from zero) which we can get by calling ordinal() method on it.
