now how do i denote this post as solved?

Anddd solved! Thank you very much!

i took away the definition inside the constructor and that got it going. Now I'm getting and exception found error
Here is my new output:

It is defined in the beginning of the program and inside the constructor. That's all.

Idk what happened to abunch of the posts but numRows is not altered after it gets set to 9 in the constructor. Accessed alot, but not altered. ?????

Never again altered*

I still can't find the problem. The only variable I missed that that method used was the array matrix[][] . Which I have added a print statement for and I have the same issue. It is equal to 0 before...

Here's my updated matrix class: (i only updated the detectErrors method, i will take correcting the methods one method at a time for easier thought-process. although hopefully whatever is the issue...

Not working at all*

I have added println statements to the detectErrors method and discovered hat for some reason, the for loop is not being entered. I am posting this reply with my phone so as soon as I get home I will...

Well after I put it in the java code format the smileys don't appear anyway so...

Oh. an open parenthese makes the faces. That makes sense. Well. Not much I can do about that. and I'll get the highlighting right real quick.
And I called all the methods in the driver program...

Um. I'm not sure why in the correction private methods it changed all the equal signs to broken heart faces but yeah...those are equal signs.
