MapLocation

Suppose that a class MapLocation has been defined for storing information about a point of interest on a map. Each MapLocation object keeps track of a grid location (row and column) and a name.

The class includes the following members:

Type Name Description
field private char row row component of location
private int column column component of location
private String name name of the location
constructor public MapLocation(char row, int column, String name) constructs a MapLocation object with given row, column, and location
method public String getCoordinates() returns the map coordinates as a String (e.g. "C8")
public String getName() returns the name of this MapLocation
public String toString() returns a String representation of the MapLocation (e.g. "arboretum (C8)")

Your task is to modify the class to be Comparable by adding an appropriate compareTo method. MapLocation objects should be ordered first by increasing row and then by increasing column and then alphabetically by name.

Rows will be specified by character values in the range of A to Z inclusive and column locations will be specified as integers greater than 0, as in: 

MapLocation loc = new MapLocation('C', 8, "arboretum");
