    This is where you are initializing 'MyItems'
    Java Code:
    they are initiated in the _sudokuBoard class this way:
    [B]MyItems SodukuCell = new MyItems();[/B]
    SodukuCell.setNewName("" + TheBoardTest[j-1][i-1]);
    SodukuCell.ChangeBorder(BorderFactory.createMatteB order(1, 1, 5, 1, Color.BLACK));
    SodukuCell.MyValue("" + TheBoardTest[j-1][i-1]);
    So now you have a 'MyItems' object named SodukoCell

    All of your attributes in the MyItems class are public (this is bad, but will show you how it works)

    because they are public you can write this: SodukoCell.myX which will return the value that you have assigned to myX. Using public attributes(or variables) within a class opens your code up to many problems. A better solution is to write private variables and public methods(called getter/setters or accessors/mutators because they retrieve the variable or change the variable) to manipulate the variables.

    you would do this by changing the myX variable within my class to:

    Java Code:
    private int myX;
    then adding two methods to the class
    //getter or accessor
    Java Code:
    public int getMyX(){
         return myX;
    //setter or mutator
    Java Code:
    public void setMyX(int x){
        myX = x;
    This is the much better approach for many reasons beyond what I able to explain in this post. Back to the SodukoCell object. Had you followed this method you could now call the getter method like this SodukoCell.getMyX();

    That's what I want to highlight.
