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(); } }
