      // Get row count
      int rowCount = rs.getRow();

      System.out.println("Total number of rows: " + rowCount);

      // Move to first row

      rs.previous();

      // Print the data of the previous row
      System.out.println("Previous Row Data: TID=" + rs.getInt("TID") +
                         ", TName=" + rs.getString("TName") +
                         ", Salary=" + rs.getDouble("Salary") +

Q.1. Advanced Java:

A) Write a Java Program to display the details of College(CID, CName, address, Year)

on JTable.

Answer :

import java.sql.*;
import javax.swing.*;
import javax.swing.table.DefaultTableModel;

public class CollegeDetailsProgram extends JFrame {
    private JTable table;

    public CollegeDetailsProgram() {
        setTitle("College Details");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(500, 500);

        // Create a table model with column names
        String[] columnNames = {"CID", "CName", "Address", "Year"};
        DefaultTableModel model = new DefaultTableModel(columnNames, 0);

        // Connect to the database and retrieve the college details
        try {
            // Step 1: Load the JDBC driver
            Class.forName("com.mysql.jdbc.Driver");

            // Step 2: Establish the connection to the database
            String url = "jdbc:mysql://localhost/mydatabase";
            String username = "root";
            String password = "password";
            Connection connection = DriverManager.getConnection(url, username, password);

            // Step 3: Retrieve the college details from the database
            String query = "SELECT * FROM college";
            Statement statement = connection.createStatement();
            ResultSet resultSet = statement.executeQuery(query);
            while (resultSet.next()) {
                String cid = resultSet.getString("CID");
                String cname = resultSet.getString("CName");
                String address = resultSet.getString("Address");
                int year = resultSet.getInt("Year");
                model.addRow(new Object[]{cid, cname, address, year});
            }

            // Step 4: Close the database resources
            resultSet.close();
            statement.close();
            connection.close();
        } catch (ClassNotFoundException e) {
            System.out.println("JDBC driver not found.");
        } catch (SQLException e) {
            System.out.println("SQL exception occurred: " + e.getMessage());
        }

        // Create the JTable and add it to the JFrame
        table = new JTable(model);
        JScrollPane scrollPane = new JScrollPane(table);
        add(scrollPane);

        // Show the JFrame
        setVisible(true);
    }

    public static void main(String[] args) {
        new CollegeDetailsProgram();
    }
}

Output :

 

B) Write a SERVLET application to accept username and password, search them into

database, if found then display appropriate message on the browser otherwise display

error message.
