TextField waiting for a user input

Question

I got a JTextfield a GetText method, and an array to store the numbers logged on the Jtextfield.

JTextField tf1 = new JTextField();
frame.add(tf1);

String tfone = tf1.getText();
int one = Integer.parseInt(tfone);

int[][] array = new int[4][5]; 
array[0][0] = one;
array[0][1] = otherValues...

The problem here is, that code execute all, so no wait for a user input into the JtextField. How can i make the jtextfield wait, until an user log in something. To latter on execute the Integer.Parseint ?

I can no change JtextField by another method cuz I'm working with GUI (Graphic User Environment.)

Answer 1

Here is the code:

JTextField tf1 = new JTextField();
frame.add(tf1);

JButton b = new JButton();
b.setText("Solve");
b.setBounds(30, 140, 110, 30);

b.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) 
            {
                String tfone = tf1.getText();
                int one = Integer.parseInt(tfone);

                int[][] array = new int[4][5]; 
                array[0][0] = one;
                array[0][1] = otherValues...
             //Here you can complete the rest of functions

});

frame.add(b);

Once the user press the button the code will end its execution.
