Java Computer Programming. Each robot: - Has a name (attribute name: string) - Has a position: given by the integer attributes x and y. - Has a direction: given by the direction attribute that takes one of the values "North", "East", "South" or "West". The name, position and direction of a robot are given to it at the moment of its creation - Can advance one step forward: with method without parameter advance () - Can turn right 90 ° to change direction (if its direction was "North" it becomes "East", if it was "East" it becomes "South", etc.): with the method without parameter right(). Robots cannot turn left. - Can display its detail with the method detail() Detail: name, position, and current direction.
