Day 7: Coding the translator

I updated the class design with this information:

1. I need a class Translator. For now, it will be a new actor, so in the package Actors there is a new class. It have some methods.
2. This class have two methods: coordinateToPosition, that translates a coordinate to a position in the array. It takes 2 arguments: the coordinate and the size of the board. The other method is positionToCoordinate that translates from a position in the board array to a coordinate.
3. There is also a private variable, coord, that have all the coordinates first part. It is needed to change it to a number. For example A=0 (0 is the position and will be the value), B=1, etc.

The code:
public class Translator { private char coord[]={'A','B','C','D','E','F','G','H','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'}; public int coordinateToPosition(String coordinate,int size){ //This method receives a coordinate //and translates it into a position int position=0; char col=coordinate.charAt(0); int row= Integer.parseInt(String.valueOf(coordinate.charAt(1))); int ncol=0; boolean flagCoordFound=false; while(flagCoordFound==false){ //I search in the array coord for the first if(coord[ncol]==col){ flagCoordFound=true; }else{ ncol++; } } //now that I have row and col I can use the formula position=ncol+size+2+(row-1)*(size+1); return position; } public String positionToCoordinate(int position,int size){ //This method receives a position //and translates it into a coordinate String finalCoord=""; boolean flagPositionFound=false; int r,c; for(r=1;r<=size;r++){ for(c=0;c<size;c++){ if((c+size+2+ (r-1)*(size+1))==position){ //found! flagPositionFound=true; finalCoord=this.coord[c]+String.valueOf(r); } } } return finalCoord; } }

This should work looking at the last post. Now, let's see if this works. For now, I will add a println in the main loop so when the engine sends a position it will write the coordinate.

coordinate=translator.positionToCoordinate(selectedMove, boardSize);

And...

A 22x22 board:

That's it, next time I think I will start with some loop and then I think I will try to group.
