Hi Friend,

Try the following code:

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

public class JTextFieldAndJTextArea extends JFrame{
JPanel panel;
JTextField text;
JTextArea area;
JScrollPane pane;
JLabel l1,l2;

public JTextFieldAndJTextArea(){
panel=new JPanel(new GridLayout(2,2));
l1=new JLabel("TextField");
text=new JTextField(15);
l2=new JLabel("TextArea");
area=new JTextArea(5,5);
pane=new JScrollPane(area);
text.addKeyListener(new KeyAdapter() {
public void keyReleased(KeyEvent e) {
String st = text.getText();
if(st.equals("")){
System.out.println("Enter the value");
}
else{
area.setText(st);
}
}
});
panel.add(l1);
panel.add(text);
panel.add(l2);
panel.add(pane);
add(panel);
setSize(300,100);
setVisible(true);
}
public static void main(String[]args){
JTextFieldAndJTextArea tf=new JTextFieldAndJTextArea();
}
}

Thanks
