Fill in Jtextfield from jComboBox

Question

I have a. txt file with strings like this:

luis;123;456;789;11/11/1111

The first part of my problem was popular jComboBox only with the first value (name), I managed to do some good, but now I need a jTextField changes to the third value as I change the selection on jComboBox. Below is how I populated the combobox, but I have no idea how to make the textfield to be filled as I alternate the selection of the combobox.

DefaultComboBoxModel<String> ComboClientes;

public void popularCombo() throws FileNotFoundException, IOException{
        ComboClientes = new DefaultComboBoxModel<>();
           String clientes = "";
           FileReader fr;
           fr = new FileReader("clientes.txt");
           BufferedReader br = new BufferedReader(fr);
           while ((clientes = br.readLine())!=null){                        
                String quebra [] = clientes.split(";");
                String nome = quebra[0];  
                ComboClientes.addElement(nome);                    
            }
           br.close();
           fr.close();
           jComboBoxCliente.setModel(ComboClientes);
        }
