Hi Friend,
Try the following code:
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class Validation extends JFrame {
JTextField CODE;
Container CONT;
JLabel LBL;
public Validation() {
CONT = getContentPane();
setBounds(0, 0, 500, 300);
CODE = new JTextField(25);
setLayout(new FlowLayout());
CONT.add(new JLabel("Enter the mobile nhmber"));
CONT.add(CODE);
CONT.add(LBL = new JLabel());
LBL.setForeground(Color.red);
setDefaultCloseOperation(EXIT_ON_CLOSE);
CODE.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent EVT) {
String value=CODE.getText();
int l=value.length();
if (EVT.getKeyChar() >= '0' && EVT.getKeyChar() <= '9'&& l==9) {
CODE.setEditable(true);
LBL.setText("");
} else {
LBL.setText("* Enter only 10 numeric digits(0-9)");
}
}
});
show();
}
public static void main(String[] args) {
new Validation();
}
}
Thanks
