Java typesafe file parser

I have a input file contains Color, Size and Shape like this:
RED LARGE TRIANGLE YELLOW SMALL SQUARE ...

Color would be RED YELLOW BLUE
Size would be LAREG SMALL MEDIUM
Shape would be TRIANGE CICLE SQUARE
All the three classes implements the same interface.

I need three bean classes which are Color, Size and Shape and driver class to read this file and loaded into each bean class and sort them, search them. Also I need make sure typesafe is used to make sure what is read is right. So Enum should be used for the bean classes.

I should give more details about this. Except those three bean classes, Color, Size and Shape which implements the same interface,
I have another bean class which has those three bean classes as property. e.g.
class MyClass{
      Color color;
      Size size;
      Shape shape;

}
And the driver class will read the file and load the input to MyClass, then sort MyClass.

I know how to read the file and parse them into those bean class, but I got stuck at how to use Color, Size, and Shape as Enum. which is typesafe.

Let me add more detail. The Color class would be like this
class Color{

    String color; //The color should be one of them, like RED BLUE YELLOW

    public String getColor(){
    return color;
    }
   public void setColor(String color){
   this.color = color;
   }
 }

The same thing for Size and Shape class.
