    Default Loop through Components of a Component

    Hello!

    I'm having trouble to loop through all the components of a JFrame. The program is going to be a Sudoku-solver, which means that I have 9 rows and 9 columns of JTextFields. Each textfield is in one of 9 JPanels and each JPanel is in one big JPanel. Now I want to loop through every textfield, and my code is shown below:

    Component[] c = p.getComponents();
     
            for (int i = 0; i < c.length; i++) 
            {
     
                Component[] c2 = c[i].getComponents(); 
     
                for (int 0 = 1; j < c2.length; j++)
                {
     
                }
     
            }

    The big JPanel is p, and what I want is to loop through each component in p, and each component in the components of p. I'm getting an error:

    "Cannot find symbol
    Symbol: method getComponents()
    Location: Class Components"

    Can someone tell me what I'm doing wrong.

    Hank

    Can you put all the components into an array when try are created, instead of trying to find them by searching the container they are in?

    Cannot find symbol
    Symbol: method getComponents()
    Location: Class Components
    Does the Components class have a method: getComponents()?
    If you don't understand my answer, don't ignore it, ask a question.

    Thank you very much! I'm still at that point where I'm figuring out what's possible and answers like this is very helpful.
