Search array in separate class ???

[JGW]

So basically I have an array saved in class, I then have a separate class which brings up a form. I wish to use this form to search within the array, i later want to work with the array to edit it.

class to hold array

    public class EventData {    
 
                             public static void main(String[] args) {
 
                                 String[] Event = new String[2];
                                 Event[0] = new String("01-01-2013", "closed");
                                 Event[1] = new String("02-01-2013", "closed");;
                                                                  }
                                    }

class to hold form

  public class Picker {
        public static void main(String[] args ) {
             final JTextField t = new JTextField(0);  
             final JTextField t1 = new JTextField(40);
             JButton b = new JButton("Open Calendar");
             JLabel l1 = new JLabel("Event");
             JPanel p = new JPanel();
             p.add(b);
             p.add(l1);
             p.add(t1);
             final JFrame f = new JFrame();
             f.getContentPane().add(p);
             f.pack();
             f.setVisible(true);
 
             b.addActionListener(new ActionListener() {
                          public void actionPerformed(ActionEvent ae) {
                                 //*If the array is set here the code works fine, 
                                // outside of the actionListener and it doesn't work*   
                                /*
                                String[] Event;
                                Event = new String[2];
                                Event[0] = "";
                                Event[1] = "01-01-2013 -- Closed";
                                 /*
                                t.setText(new DatePicker(f).setPickedDate());
                                String input = t.getText();
 
                                 for(String ent: Event) {
                                      if(ent.startsWith(input)){
                                             t1.setText("" + ent);
                                                                       }
                                       else {
                                              t1.setText ("No Event");
                                              }
                                                                       }
 
 
                                                               }
                                                                                     }
                                                                        );
 
                               }
}

any suggestions, I have tried placing the array in a method and calling it using EventData.Ent however this didn't work either

this didn't work

Please explain what happened.
There aren't any class level arrays in the posted code. To access an array in another class, the array must be defined at the class level.


Please edit your post and wrap your code with
[code=java]
<YOUR CODE HERE>
[/code]
to get highlighting and preserve formatting.

Also properly format the code. There should NOT be anything on a line following an ending bracket: }
}s should be inline with the start of the line with its pairing {

What do you mean by "the array must be defined at the class level" I'm a beginner in Java.

There are several places to define variables: inside the class and inside a method.
Variables defined in a method only exist while the method is being executed. They disappear when the method stops executing. Variables defined in the class (not in a method) will continue to exist as long as the instance of the class exists.
