Hi Friend,

Try the following code:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.Calendar;

class DisplayMesage extends JFrame {
    JTextField text; 
    JLabel label;
    public DisplayMesage() {
        text = new JTextField(5);
        text.setEditable(false);
        text.setFont(new Font("Arial", Font.PLAIN, 20));

        label = new JLabel();
        label.setFont(new Font("Arial", Font.PLAIN, 22));
        label.setForeground(Color.BLUE);

        JPanel time = new JPanel();
        time.setLayout(new FlowLayout());
        time.add(text); 
        JPanel message = new JPanel();
        message.setLayout(new FlowLayout());
        message.add(label); 

        add(time,BorderLayout.NORTH);
        add(message,BorderLayout.SOUTH);
        setSize(300,100);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
        setVisible(true);
        javax.swing.Timer t = new javax.swing.Timer(1000, new ClockListener());
        t.start();
    }
        class ClockListener implements ActionListener {
        public void actionPerformed(ActionEvent e) {
            Calendar now = Calendar.getInstance();
            int h = now.get(Calendar.HOUR_OF_DAY);
            int m = now.get(Calendar.MINUTE);
            int s = now.get(Calendar.SECOND);
            text.setText("" + h + ":" + m + ":" + s);
            if(h<12){
                label.setText("Good Morning!");
            }
            else if(h>12&&h<15){
                label.setText("Good Afternoon!");
            }
            else if(h>15&&h<19){
                label.setText("Good Evening!");
            }
            else{
                label.setText("Good Night!");
            }
    }
        }
    public static void main(String[] args) {
        DisplayMesage f = new DisplayMesage();
        }
}
