Question

I have a JPanel full of JTextFields…

for (int i=0; i<maxPoints; i++) {     JTextField textField = new JTextField();     points.add(textField); } 

How do I later get the JTextFields in that JPanel? Like if I want their values with

TextField.getText(); 

Thanks

Well bear in mind they didn’t get there by them selves ( I think a read some questions about dynamically creating these panels at runtime )

In the answers posted there, someone said you should kept reference to those textfields in an array. That’s exactly what you need here:

List<JTextField> list = new ArrayLists<JTextField>();  // your code... for (int i=0; i<maxPoints; i++) {      JTextField textField = new JTextField();     points.add(textField);     list.add( textField ); // keep a reference to those fields. } 

// Later

for( JTextField f : list ) {     System.out.println( f.getText() ) ; } 

Wasn’t that easy?

Just remember to keep these kinds of artifacts ( list ) as private as possible. They are for your control only, I don’t think they belong to the interface.

Let’s say you want to get the array of texts, instead of

 public List<JTextField> getFields(); 

You should consider:

 public List<String> getTexts(); // get them from the textfields ...
