how can I iterate over text fields not in an array

[IKerr.]

Hi,

I have some code which declares a whole bunch of text fields individually,
ie

JTextField jTextField1 = new JTextField();
JTextField jTextField2 = new JTextField()
etc .....

how can I iterate over them ? What I want to do is something like:

String[] customerDetails = new String[19];

for(int i = 0; i<customerDetails.length;i++){
customerDetails = jTextField+i.getText();
}

This is a bit simplified because there beans on the page which inheret from
JTextField, and comboboxes which I also want to grab text from, but rather
than having to rewrite a whole load of code to make a JTextField[] or to
issue individual getText()s I was wondering if there was a way of iterating
over what I have ?

thanks

Iain

I couldn't find the thread at first, but:

java.awt.Component components[] = jPanel1.getComponents ();
if (components.length > 0)
{
Collection textFields = new java.util.LinkedList ();
// or ArrayList if you must

for (int i = 0; i < components.length; i++)
{
System.out.println (components.toString ());

if (components instanceof JTextField)
textFields.add (components);
}

for (java.util.Iterator it = textFields.iterator ();
it.hasNext ()
{
JTextField tf = (JTextField)(it.next ());
System.out.println (tf.getText ());
}
}
