I'm working on a problem to help try and improve my java skills before I sit SCJA:

I have an array, "word", with three characters "D" "O" and "G".

I'm trying to search through a larger 2D array and then print out all three characters when they are matched in a row.

I have worked this out on a white board with someone before, but I cant remember how I solved it... derp.

This is the code I currently have:


I feel like I'm close to solving it.>

How close? What's your program doing now? What should it be doing?

Well, I'm trying to get it to output DOG. At the minute its outputting DDODDDOG.

I thought I knew what I was doing but now I'm a bit lost and confused. I want it to compare every single character in square to the characters in word, and output the characters that match, but only if it finds them in the sequence D-O-G.

I know we're not supposed to give out "answers" but I couldn't resist giving this a try. Works for any size 'square' and 'word'. Prints out list of square coordinates where 'd-o-g' was found.
