```Hello, I've been working on this program for a long time but can't seem to get it to work.. The first array is the input file, then a class, another class and the actual program. Could anyone see what is wrong? I'm sorry if the program doesn't make any sense at all  I'm just starting to learn this..

The exercise wants us to do the following:
5,4 4,5 8,7
Add behind 6,3 3,2 9,6 4,3
Add in front 5,5 7,8 6,5 6,4
These are coordinates in the form(x,y) and the x coordinates need to be raised by 1.

5,4 4,5 8,7=6,3 3,2 9,6 4,3=7,6=9,8=5,5 7,8 6,5 6,4
