Mars Rover Problem for ThoughtWorks

Design Decisions

Class Position

I created a general Position class from which derives the 2DPosition just in case we extend the position to 3D, 4D, ... ND in the future.

Class Program

Like in the case of the position I decided to create a general Program from which derives the current LRMProgram (the program with instructions L, R and M), just in case we need to expand later the program with new commands for the rovers.

Exceptions

I created two types of exceptions one for the exceptions derivated from executing the program of the Rover and another for the exceptions derivated from loading the data.

How to execute

Create the .data file

To load any rover data you could write a .data (preferably in the Data folder) file with the format that was passed by mail.

Building

I use Maven to build the project so you're gonna need it. To build the project simply execute this in the folder where the pom.xml file is located.:

mvn install

Execute

To execute the program you just need to write:

java -jar targuet/MarsRoverProblem.jar $PathToDataFile

Being $PathToDataFile the file with Rover info that you are gonna enter.

For example:

java -jar targuet/MarsRoverProblem.jar .\Data\RoverData.data
