public class J_Text extends JFrame{
private JTextField[] m_testfield = {
new JTextField("SHOWN TEST:" ,8),new JTextField("Shown",15),new JTextField("Hideen test:",8)
};
private JPasswordField m_passwordField =new JPasswordField("HIdeen",15);

public J_Text()
{
super("EXAMPLE");
Container container =getContentPane();
container.setLayout(new FlowLayout());

m_testfield[0].setEditable(false);
m_testfield[2].setEditable(false);

for(int i=0;i<3;i++)
container.add(m_testfield[i]);
container.add(m_passwordField);

J_Handler handler =new J_Handler();
m_testfield[1].addActionListener(handler);
m_passwordField.addActionListener(handler);

setSize(325,100);
