Programming Connect Four grid in Java
I have been trying to get this conection four GUI working, but for some reason, the grid and the size of the array don't seem to sync up very well. I have been playing around with the code but it doesn't seem to be working very well. The array works in displaying the contents in a grid way in the terminal, but not so well when inside of the jframe. Here is the code for each file. the Frame file contains the code for the GUI, the grid file contains the code for the grid which hold the values in the connect four grid. I don't know what logic is for, and the ConnectFour file contains the main function. These are it's contents
