    Default adding text to JLabel during actionPerformed

    Ok so I want the user to enter their name and age and when they press a JButton the program sends a welcome message to the user "Welcome first name last name"

    here is my code:
     
    import javax.swing.*;
    import java.awt.*;
    import java.awt.event.*;
     
    public class message extends JFrame implements ActionListener
    {
    	JLabel Lname, Fname, Mname, Welcome;
    	JTextField Field1, Field2, Field3;
    	JButton click;
     
    	public message()
    	{
    		setLayout(new FlowLayout(FlowLayout.LEFT));
     
    		Lname = new JLabel("Last Name");
    		Field1 = new JTextField(15);
    		Fname = new JLabel("First Name");
    		Field2 = new JTextField(10);
    		Mname = new JLabel("Age");
    		Field3 = new JTextField(3);
    		click = new JButton("Click When Done");
    		Welcome = new JLabel();
     
    		click.addActionListener(this);
     
    		this.add(Lname);
    		this.add(Field1);
    		this.add(Fname);
    		this.add(Field2);
    		this.add(Mname);
    		this.add(Field3);
    		this.add(click);
    		this.add(Welcome);
    	}
     
    	public static void main(String[] args) 
    	{
    		message frame = new message();
    		frame.setSize(300, 300);
    		frame.setLocationRelativeTo(null);
    		frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE);
    		frame.setVisible(true);
    	}
     
    	public void actionPerformed(ActionEvent e)
    	{
    		Welcome.setText("Welcome " + Field2 + " " + Field1);
    	}
     
    }

    The actionPerformed method isnt working properly, it sends a message like "Welcome javax.swing......" instead of "Welcome John Smith"

    Default Re: adding text to JLabel during actionPerformed

    ok got it...
    instead of
    Welcome.setText("Welcome " + Field2 + " " + Field1);

    I should have had:
    Welcome.setText("Welcome " + Field2.getText() + " " + Field1.getText());
