    how to do this if it an array like this :
    How many items are in the array?
    For example if there are 20 JTextField objects referenced in the array, where do you want all 20 of them displayed in the GUI?

    To access one element of the array, use array notation: theArrayName[theIndex]
    If you don't understand my answer, don't ignore it, ask a question.

    I just want when the user type in the text field it should be in the center like this :

    I know how to do this for normal JTextField
    Replace the "normal" with the array notation: theArrayName[theIndex]

    If that is not your problem, please post the code you are having problems with and add some comments saying what the problem is. Be sure to wrap any posted code in code tags.

    While you have created the 2D array to house your fields, you need to instantiate the JTextField components in your array.

    for (int i =0; i < userInputArray.length; i++) {
    for (int j =0; j < userInputArray[0].length; j++) {
    userInputArray[i][j] = new JTextField();
    }
    }

    @jackar56 What question are you trying to answer? I don't see a 2D array in OPs question.
