A. PENDAHULUAN

Pada kesempatan ini, penulis membuat suatu program aplikasi sederhana berbasis

Java dan database MySQL. Program aplikasi yang dibuat berupa Contact Book Sederhana

yang dapat digunakan untuk mengelola, yaitu menyimpan, mengedit, dan menghapus data

no. telepon.

B. PEMBAHASAN

1. Desain Database Aplikasi

Database aplikasi dibuat dengan menggunakan MySQL. Berikut adalah keterangan

lengkap dari database aplikasi Contact Book Sederhana.

Nama database : dbcontact

Jumlah tabel : 2

Keterangan tabel:

Nama Tabel : tblcontact Nama Tabel : tbldetailNama Field Type Data Nama Field Type DataidContact int(5), auto increment id int(5), auto incrementnama varchar(30) idContact int(5)alamat varchar(50) telp varchar(15)email varchar(50) ket varchar(20)deskripsi text

Aplikasi akan menyimpan data contact berupa data identitas pemilik no telepon pada

tblcontact dan data no telepon akan disimpan dalam tbldetail. Dalam hal ini, satu

individu pemilik dapat memiliki lebih dari satu no telepon. Sehingga dapat dibuat

suatu relasi antar tabel yang bersifat one to many, seperti pada gambar berikut.

tblcontact tbldetail* idContact * id

nama ** idContactalamat telpemail ketdeskripsi

Dimana field bertanda (*) sebagai primary key dan field bertanda (**) sebagai foreign

key. Dalam relasi di atas dapat diperhatikan bahwa tblcontact dan tbldetail memiliki

relasi one to many dengan penghubung idContact yang menjadi prymary key di

tblcontact merupakan foreign key di tbl detail. Artinya, jika dilihat dari tblcontact, 1

data kontak bisa memiliki lebih dari satu data detail telepon atau jika dilihat dari

tbldetail, lebih dari satu data detail telepon dapat dimiliki oleh 1 data kontak.

2. Tampilan dan Kode Program

Program aplikasi ini berbasis java. Project aplikasinya diberi nama

SimpleContactBook. Project terdiri dari 2 package yaitu package ui yaitu untuk

membuat user interface dan package utility untuk keperluan penting bagi package ui.

a. Package utility terdiri dari 2 class yaitu class Koneksi.java dan ModelTabel.java.

1) Class Koneksi.java

Class ini berfungsi untuk melakukan koneksi ke database dan mengeksekusi

setiap query yang akan dijalankan, sehingga setiap memerlukan koneksi ke

database atau setiap akan mengeksekusi suatu statement query hanya perlu

memanggil class ini.

Codenya:

package utility;

import java.sql.Connection;import java.sql.DriverManager;import java.sql.ResultSet;import java.sql.Statement;

public class Koneksi {public void executeUpdate(String query) throws Exception{

String driver = "com.mysql.jdbc.Driver";Class.forName(driver);Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/

dbContact","root","");Statement st = con.createStatement();st.executeUpdate(query);

}

public ResultSet executeSelect(String query) throws Exception{

String driver = "com.mysql.jdbc.Driver";Class.forName(driver);Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/

dbContact","root","");Statement st = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,

ResultSet.CONCUR_READ_ONLY);return st.executeQuery(query);

}

}

2) Class ModelTabel.java

Class ini berfungsi dalam pembuatan tabel pada FormUtama.java dan

FormDetail.java untuk menampilkan data contact.

Code:

package utility;import java.sql.*;import javax.swing.table.AbstractTableModel;import utility.Koneksi;

public class ModelTabel extends AbstractTableModel {private static final long serialVersionUID = 1L;private int jmlBaris;private String[] namaKolom;private Koneksi koneksi;private ResultSet rs;

public ModelTabel(Koneksi koneksi, String[] namaKolom) {this.koneksi = koneksi;this.namaKolom = namaKolom;

}

public Object getValueAt(int noBaris, int noKolom) {try {

rs.absolute(noBaris+1);return rs.getObject(noKolom+1);

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

}return "";

}

public int getColumnCount() {return namaKolom.length;

}

public int getRowCount() {return jmlBaris;

}

public String getColumnName(int kolom) {String nmKolom;nmKolom = namaKolom[kolom];return nmKolom;

}

public void runQuery(String query) throws Exception {if (query.toLowerCase().startsWith("select")) {

rs = koneksi.executeSelect(query);rs.last();this.jmlBaris = rs.getRow();this.fireTableDataChanged();

}else {

koneksi.executeUpdate(query);}

}

public void setEmpty() {jmlBaris = 0;this.fireTableDataChanged();

}}

b. Package ui terdiri dari 4 class yaitu class FormUtama.java, FormAddContact.java,

FormAddNumber.java, dan FormDetail.java.

1) FormUtama.java

Dalam FormUtama.java kita dapat melakukan searching data contact, dan

menampilkan data kontak, serta terdapat akses untuk menambah kontak baru.

Code:

package ui;import javax.swing.*;import javax.swing.table.*;import java.awt.*;import java.awt.event.*;import java.sql.*;import ui.*;import utility.*;

public class FormUtama extends JFrame implements ActionListener {private static final long serialVersionUID = 1L;public String dataSearch;private JButton btnAdd;

public FormUtama() { setDefaultCloseOperation(EXIT_ON_CLOSE); con = new Koneksi(); modelSearch = new ModelTabel(con, namaKolom); formAdd = new FormAddContact(this); txtSearch = new JTextField(42); paneSearch = new JScrollPane(); tblSearch = new JTable(); btnSearch = new JButton("Search");

btnAdd = new JButton("Add New Contact"); btnShow = new JButton("Show All"); paneBack = new JPanel(); paneFront = new JPanel(); btnAdd.addActionListener(this); btnShow.addActionListener(this); btnSearch.addActionListener(this); setLayout(null); tblSearch.setModel(modelSearch); tblSearch.setFont(new Font("Calibri", 0, 11)); tblSearch.addMouseListener(new MouseAdapter() { public void mouseClicked(MouseEvent e) { tblSearchMouseClicked(e); } }); paneSearch.setViewportView(tblSearch); paneBack.setBackground(new java.awt.Color(0, 100, 150)); paneFront.setBackground(new java.awt.Color(255, 255, 255));

paneBack.setBounds(0, 0, 600, 480); paneFront.setBounds(10, 10, 575, 430); txtSearch.setBounds(20, 24, txtSearch.getPreferredSize().width, txtSearch.getPreferredSize().height); btnSearch.setBounds(30 + txtSearch.getPreferredSize().width, 20, btnSearch.getPreferredSize().width, btnSearch.getPreferredSize().height); tblSearch.setBounds(20, 55, 555, 330); paneSearch.setBounds(20, 55, 555, 330); btnShow.setBounds(20, 400, btnShow.getPreferredSize().width, btnShow.getPreferredSize().height); btnAdd.setBounds(30 + btnShow.getPreferredSize().width, 400, btnAdd.getPreferredSize().width, btnAdd.getPreferredSize().height); add(txtSearch); add(btnSearch); add(btnAdd); add(btnShow); add(paneSearch); add(paneFront); add(paneBack);

setSize(600, 480); }

public Koneksi getConnection() {return this.con;

}

public void SearchContact() throws Exception {dataSearch = txtSearch.getText();modelSearch.runQuery("Select idContact, nama, alamat, email from tblcontact where

nama like '%"+dataSearch+"%'");}

public void AddContact() throws Exception {

formAdd.setLocationRelativeTo(this);formAdd.setVisible(true);

}

public void ShowContact() throws Exception {modelSearch.runQuery("Select idContact, nama, alamat, email from tblcontact");

}

public void tblSearchMouseClicked(MouseEvent evt) { FormDetail formDetail = new FormDetail(this, String.valueOf(tblSearch.getValueAt(tblSearch.getSelectedRow(),0)) ); formDetail.setLocationRelativeTo(this); formDetail.setVisible(true); } public static void main(String args[]) throws Exception { FormUtama formUtama = new FormUtama(); formUtama.setVisible(true); formUtama.setTitle("Contact Book Application"); formUtama.setResizable(false); formUtama.setLocation(300, 100); }

public void actionPerformed(ActionEvent e) {if (e.getSource() == btnAdd)

try {this.AddContact();

} catch (Exception e1) {e1.printStackTrace();

}else if (e.getSource() == btnShow)

try {this.ShowContact();


}else if (e.getSource() == btnSearch)

try {this.SearchContact();txtSearch.setText("");


}}

}

3) FormAddNumber.java

Fungsi form ini adalah untuk menambahkan detail no telepon baru ataupun

mengedit detail no telpon dari suatu data kontak. Form ini akan dipanggil

melalui FormDetail.java

4) FormDetail.java

Form ini berfungsi untuk menampilkan detail lengkap dari suatu data kontak.

Form ini akan dipanggil dari FormUtama.java dengan mengklik tabel data

kontak. Melalui form ini kita juga memiliki akses untuk mengedit detail dan

kontak, serta menghapus detail atau kontak.

Code:

C. PENUTUP

Program aplikasi ini sudah cukup membantu dalam manajemen data no telepon.

Tetapi, masih terdapat kekurangan-kekurangan dalam pembuatan ataupun

penggunaannya. Selanjutnya penulis akan berusaha mengembangkan dan memperbaiki

program aplikasi ini agar menjadi lebih baik.
