House Rent System using Java Mysql

This tutorial will teach you how to make a house rest system step by step. This system helpful you to learn JDBC connective and learn crud operation.

First Establish the Database Connection

Add the Sql Namespace

import java.sql.*;

Database Connection

Connection con;
PreparedStatement pst;

public void Connect()
    {
        try {
            Class.forName("com.mysql.jdbc.Driver");
            con = DriverManager.getConnection("jdbc:mysql://localhost/houserent","root","");
        } catch (ClassNotFoundException ex) {
            Logger.getLogger(HouseRent.class.getName()).log(Level.SEVERE, null, ex);
        } catch (SQLException ex) {
            Logger.getLogger(HouseRent.class.getName()).log(Level.SEVERE, null, ex);
        }
            
    }

Paste following code inside the Save Button

   String hno,address,kit,bath,rooms,rent;
            hno = txtNo.getText();
            address = txtAddress.getText();  
            kit = txtKit.getText();
            rooms = txtRooms.getText();
            bath = txtBath.getText();
            rent = txtRent.getText();

        try {
            pst = con.prepareStatement("insert into records (houseno,address,kitchen,rooms,bathroom,Rent)values(?,?,?,?,?,?)");
             pst.setString(1,hno);
            pst.setString(2,address);
            pst.setString(3,kit);
            pst.setString(4,rooms);
            pst.setString(5,bath);
            pst.setString(6,rent);
            pst.executeUpdate();
            JOptionPane.showMessageDialog(this, "Record Saved");

             txtNo.setText("");
             txtAddress.setText("");
             txtKit.setText("");
             txtRooms.setText("");
             txtBath.setText("");
             txtRent.setText("");
             txtNo.requestFocus();
             Table();

        } 
        catch (SQLException ex) 
        {
            ex.printStackTrace();
        }

Load the Table

  public void Table()
    {
        try {
            pst = con.prepareStatement("SELECT * FROM records");
            ResultSet Rs = pst.executeQuery();
            DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
           
            ResultSetMetaData RSMD = Rs.getMetaData();
            int CC = RSMD.getColumnCount();
            DefaultTableModel DFT = (DefaultTableModel) jTable1.getModel();
            DFT.setRowCount(0);
            
            while(Rs.next())
           {  
               Vector v2 = new Vector();
                for (int ii = 1; ii <= CC; ii++) {
                    v2.add(Rs.getString("houseno"));
                    v2.add(Rs.getString("address"));
                    v2.add(Rs.getString("kitchen"));
                     v2.add(Rs.getString("rooms"));
                     v2.add(Rs.getString("bathroom"));
                     v2.add(Rs.getString("Rent"));
                }
                DFT.addRow(v2); 
            }
            jTable1.setModel(model);

        } catch (SQLException ex) {
            ex.printStackTrace();
        }       
    }
