1.Displaying Views

Steps:

1.     On NetBeans, create folder  and file structure as shown below:

1.1   MenuView.java

Design:

 

Code:

package Views;

public class MenuView extends javax.swing.JFrame {

    public MenuView(){

        super("Menu");

        initComponents();

    }

    public MenuView(java.awt.event.ActionListener listener) {

    this();

    EmployeesView.addActionListener(btnSignup, listener,"signup");

    EmployeesView.addActionListener(btnEmpList, listener,"empList");

    EmployeesView.addActionListener(btnUpdate, listener,"update");

    EmployeesView.addActionListener(btnDelete, listener,"delete");

    this.setVisible(true); 

    }

}

1.2   SignupView.java

Design:

Code:

package Views;

public class SignupView extends javax.swing.JFrame {

    public SignupView(){

        super("Employee Signup");

        initComponents();

    }

    public SignupView(java.awt.event.ActionListener listener) {

        this();

        EmployeesView.addActionListener(btnSave, listener,"save");

        this.setVisible(true);

    }

}

1.3   EmpListView.java

Design:

 

Code:

package Views;

public class EmpListView extends javax.swing.JFrame {

    public EmpListView() {

        super("Employees");

        initComponents();

    }

    public EmpListView(java.awt.event.ActionListener listener){

       this();

       EmployeesView.addActionListener(btnClose, listener,"close");

       this.setVisible(true);

    }

}

1.4   EmpEditDeleteView.java

Design:

Code:

package Views;

public class EmpEditDeleteView extends javax.swing.JFrame {

    public EmpEditDeleteView() {

        super("Employee Edit/Delete");

        initComponents();

    }

   public EmpEditDeleteView(java.awt.event.ActionListener listener,String btnText){

       this();

       btnAction.setText(btnText);

       EmployeesView.addActionListener(btnAction, listener,btnAction.getText());

       EmployeesView.addActionListener(btnSearch, listener,"search");

       this.setVisible(true); 

   }

}

2.     On MSAccess 2003, create a database EmployeesDB.mdb and on query tab write the SQL statement below:

CREATE TABLE Employees

(

id AUTOINCREMENT ,

EmpName TEXT(50),

EmpAddress TEXT(100)

)

Note: Save the database to the EmployeesMVC folder.

3.     On  EmployeesMVC.java type the following:

package employeesmvc;

import Models.*;

import Views.*;

import Controllers.*;

public class EmployeesMVC {

    public static void main(String[] args) {

        EmployeesModel model = new EmployeesModel(MSAccessDB.Connect());

        EmployeesView view = new EmployeesView(model);

        EmployeesController controller = new EmployeesController(model,view);

    }

}

4.     On the EmployeesModel.java type the following:

package Models;

import java.sql.*;

public class EmployeesModel extends PersonsModel {

    private int id;

    Connection db;

    public int getId(){return id;}

    public void setId(int id){this.id= id;}

    public EmployeesModel(){}

    public EmployeesModel(Connection db){

    this.db=db;

    }   

}

5.     On PersonsModel.java type the following:

package Models;

public class PersonsModel {

    private String name;

    private String address;

    public void setName(String name){this.name=name;}

    public String getName(){return name;}

    public void setAddress(String address){this.address=address;}

    public String getAddress(){return address;}

    public PersonsModel(){}

}

6.     On  EmployeesView.java type the following:

package Views;

import Models.*;

import java.awt.event.*;

import javax.swing.*;

public class EmployeesView {

    EmployeesModel model;

    MenuView menu;

    SignupView signup;

    EmpListView empList;

    EmpEditDeleteView empEditDelete;

   

    public EmployeesView(){}

    public EmployeesView(EmployeesModel model){

    this.model=model;

    }

    public void menu(ActionListener listener){

        menu = new MenuView(listener);

    }

    public void signup(ActionListener listener){

        signup= new SignupView(listener); 

    }

    public void empList(ActionListener listener){

        empList= new EmpListView(listener);

    }

    public void update(ActionListener listener, String btnText){

        empEditDelete =  new EmpEditDeleteView(listener,btnText);

    }

    public static void addActionListener(JButton btn, ActionListener listener,String action){

        btn.addActionListener(listener);

        btn.setActionCommand(action);

    }

}

7.     On  EmployeesController.java type the following:

package Controllers;

import Models.*;

import Views.*;

import java.awt.event.*;

public class EmployeesController {

    EmployeesModel model;

    EmployeesView view;

    public EmployeesController(){}

    public EmployeesController(EmployeesModel model,EmployeesView view){

        this.model=model;

        this.view=view;

        view.menu(new btnMenuActionListener());

    }

    class btnMenuActionListener implements ActionListener{

        @Override

        public void actionPerformed(ActionEvent e){

            String action = e.getActionCommand();

            if(action.equals("signup")){

                view.signup(new btnSignupActionListener());

            }else if(action.equals("empList")){

                view.empList(new btnEmpListActionListener());

            }else if(action.equals("update")){

                view.update(new btnEditDeleteActionListener(),"Update");

            }else{

                view.update(new btnEditDeleteActionListener(),"Delete");

            }

        }

    }

    class btnSignupActionListener implements ActionListener{

        @Override

         public void actionPerformed(ActionEvent e){}

    }

  

    class btnEditDeleteActionListener implements ActionListener{

        @Override

         public void actionPerformed(ActionEvent e){}

    }

    class btnEmpListActionListener implements ActionListener{

        @Override

         public void actionPerformed(ActionEvent e){}

    }   

}

8.     Put your code to the test, nice jobJ
