Using JTextField as an array.

Question

Hi I would like some help with createing a JTextField array. I cant seem to find anything wrong with my code but it keeps giving me an Error.
Error Message: java.lang.ArrayIndexOutOfBoundsException
This is what my code looks like.
//Declare Component
JTextField Length[];
for(int i = 0; i < 5; i++)
Length[i] = new JTextField("", 5);
c.gridx = i;
c.gridy = 0;
panMiddle.add(Length, c);
Please let me know what im doing wrong.

You seem to have several things in error. Here is one way to do this. It creates an array of 4 JTextFields. A frequent beginner's mistake is to initialize the array but to forget to initialize the individual items, something that must be done if the items are objects (i.e., are not primative types such as int).
public class MyClass extends JPanel
    private JTextField[] textFieldArray = new JTextField[4]; //array declared and initialized
    public MyClass()
        for (int i = 0; i < textFieldArray.length; i++)
            textFieldArray[i] = new JTextField(12); //init each array item here
            panMiddle.add(textFieldArray); // add it to my form here.
