I am a beginner in programming, and this course I suppose to create Sudoku generator by using java in NetBeans
So far I did the code for generating numbers in a JTable and show the whole solution upon request
But I am straggle in how to disable writing in the visible numbers or the visible cells but enable in the empty cells
I used this code but as it is cleat it disable typing in the whole table
Also I cant think of a way that enables me to get the answer from the empty cells and compare it with the actual solution!!!
