Hi Friend,

Try the following code:

1)SplashScreen.java
import javax.swing.*;

public class SplashScreen extends JFrame{
public static void main(String[] arg) {
JWindow window = new JWindow();
window.getContentPane().add(new JLabel("Loading Login Page...",SwingConstants.CENTER));
window.setBounds(200, 200, 200, 100);
window.setVisible(true);
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
window.setVisible(false);
LoginDemo form=new LoginDemo();
form.setVisible(true);
form.setSize(300,100);
window.dispose();
}
}

2)LoginDemo.java:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.sql.*;
class LoginDemo extends JFrame{
JButton SUBMIT;
JPanel panel;
JLabel label1,label2;
final JTextField text1;
final JPasswordField text2;
LoginDemo(){
label1 = new JLabel();
label1.setText("UserName:");
text1 = new JTextField(15);
label2 = new JLabel();
label2.setText("Password:");
text2 = new JPasswordField(15);
SUBMIT=new JButton("Login");
panel=new JPanel(new GridLayout(4,2));
panel.add(label1);
panel.add(text1);
panel.add(label2);
panel.add(text2);
panel.add(SUBMIT);
add(panel,BorderLayout.CENTER);
SUBMIT.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ae){
String value1=text1.getText();
String value2=text2.getText();
String user1="";
String pass1="";
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test";, "root", "root");
Statement st = con.createStatement();
ResultSet res = st.executeQuery("SELECT * FROM login where username='"+value1+"' && password='"+value2+"'");
while (res.next()) {
user1 = res.getString("username");
pass1 = res.getString("password");
}
if (value1.equals(user1) && value2.equals(pass1)) {
JOptionPane.showMessageDialog(null,"Welcome");

}
else{
JOptionPane.showMessageDialog(null,"Incorrect login or password","Error",JOptionPane.ERROR_MESSAGE);
}
}
catch(Exception e){
System.out.println(e.getMessage());
}
}
});
}
public static void main(String arg[]) {
LoginDemo frame=new LoginDemo();
frame.pack();
frame.setVisible(true);
}
}

Thanks
