Membuat Aplikasi tiket di netbeans

1. Melanjutkan project aplikasi kasir dan aplikasi tiket wisata di java Netbeans, pertama buat Package baru dengan nama tiket. Kita akan buat aplikasi tiket di package ini

Klik enter, Kenapa already exists karena saya sudah membuat package dengan nama tiket.
2. Selanjutnya buat JFrame Form di Package tiket dengan nama TiketWisata

Klik Finish
3. Buka JFrame tiket wisata kemudian sesuaikan desain seperti dibawah

Keterangan :
1. jButton : btnLihatData
2. jComboBox : cJenisWisata
3. jButton : btnBeli
4. jMenu Bar didalam nya ada jMenu Item : jMenuItem1

4. Setelah desain sudah selesai tulis kodingan di tab source
Pertama import fungsi yang akan kita gunakan di bagian atas bawahnya package

5. Deklarasi ComboBox model

6. Kemudian saat jMenu Item Home di klik akan beralih ke Frame Home tambahkan kode berikut :

Home home = new Home();
home.setLocationRelativeTo(this);
home.setVisible(true);
this.setVisible(false);

7. Saat frame dijalankan akan menampilkan model ComboBox tambahkan kode dibawah ini :

mdlJenisWisata.addElement("Pilih Wisata");
mdlJenisWisata.addElement("Jatim Park 1");
mdlJenisWisata.addElement("Jatim Park 2");
mdlJenisWisata.addElement("Jatim Park 3");
mdlJenisWisata.addElement("Eco Green Park");
cJenisWisata.setModel(mdlJenisWisata);
8. Saat btnBeli diklik akan beralih ke Frame yang dipilih tambahkan kode berikut :
Kita akan buat frame nya setelah ini jika ada yang merah abaikan dulu

JTP1 jtp1 = new JTP1();
JTP2 jtp2 = new JTP2();
JTP3 jtp3 = new JTP3();
EGP egp = new EGP();
if(cJenisWisata.getSelectedItem().equals("Jatim Park 1")){
jtp1.setLocationRelativeTo(this);
jtp1.setVisible(true);
}else if(cJenisWisata.getSelectedItem().equals("Jatim Park 2")){
jtp2.setLocationRelativeTo(this);
jtp2.setVisible(true);
}else if(cJenisWisata.getSelectedItem().equals("Jatim Park 3")){
jtp3.setLocationRelativeTo(this);
jtp3.setVisible(true);
}else if(cJenisWisata.getSelectedItem().equals("Eco Green Park")){
egp.setLocationRelativeTo(this);
egp.setVisible(true);
}else{
JOptionPane.showMessageDialog(this, "Silahkan pilih jenis wisata", "Pilih jenis wisata !", JOptionPane.WARNING_MESSAGE);
}
9. Saat btnLihatData di klik akan menampilkan data penjualan.

DataPenjualan data = new DataPenjualan();
data.setLocationRelativeTo(this);
data.setVisible(true);
10. Sekarang kita buat frame yang dibutuhkan kemudian membuat class untuk funsi dan data
Cara nya sama saat kita membuat frame TiketWisata tapi namanya sesuaikan seperi pada gambar dibawah :

Keterangan :
Data.java adalah Class
DataPenjualan.java : JFrame Form
EGP.java : JFrame Form
Fungsi.java : Class
JTP1,2,3 : JFrame Form
11. Kemudian pertama kita isi kodingan untuk Fungsi.java

package tiket;

import java.text.DecimalFormat;
import java.text.DecimalFormatSymbols;
import javax.swing.JTable;
import javax.swing.table.TableColumn;
import static tiket.Data.jenisWisata;
import static tiket.Data.ArrSubTotal;
import static tiket.Data.ArrJumlahTiket;
import static tiket.Data.ArrTanggal;
/**
*
* @author djavu
*/
public class Fungsi {

public static int getSubTotal(int a,int b){
int total = a*b;
return total;
}
public static int getJumlah(int a,int b){
int total = a+b;
return total;
}
public static int getTotal(int a,int b,int c){
int total = a+b+c;
return total;
}

public static void setArray(String jenis,String tgl, int subs, int jumlah){
jenisWisata.add(jenis);
ArrSubTotal.add(subs);
ArrJumlahTiket.add(jumlah);
ArrTanggal.add(tgl);
}
public static void delArray(int i){
if(jenisWisata.size()>0){
jenisWisata.remove(i);
ArrSubTotal.remove(i);
ArrJumlahTiket.remove(i);
ArrTanggal.remove(i);
}
}
public static void delAll(){
if(jenisWisata.size()>0){
jenisWisata.removeAll(jenisWisata);
ArrSubTotal.removeAll(ArrSubTotal);
ArrJumlahTiket.removeAll(ArrJumlahTiket);
ArrTanggal.removeAll(ArrTanggal);
}
}
public static String setIDR(int var){
//rupiah format
String idr;
DecimalFormat rupiah = (DecimalFormat) DecimalFormat.getCurrencyInstance();
DecimalFormatSymbols rp = new DecimalFormatSymbols();
rp.setCurrencySymbol("IDR. ");
rp.setMonetaryDecimalSeparator(',');
rp.setGroupingSeparator('.');
rupiah.setDecimalFormatSymbols(rp);
//end
idr = rupiah.format(var);
return idr;
}

public static JTable setKolom(JTable tblPembelian){
TableColumn column;
tblPembelian.setAutoResizeMode(javax.swing.JTable.AUTO_RESIZE_OFF);
column = tblPembelian.getColumnModel().getColumn(0);
column.setPreferredWidth(40);
column = tblPembelian.getColumnModel().getColumn(1);
column.setPreferredWidth(450);
column = tblPembelian.getColumnModel().getColumn(2);
column.setPreferredWidth(120);
column = tblPembelian.getColumnModel().getColumn(3);
column.setPreferredWidth(148);
column = tblPembelian.getColumnModel().getColumn(4);
column.setPreferredWidth(182);
return tblPembelian;
}
}

12. Setelah itu kita isi kode untuk Data.java ini isinya adalah Array yang akan kita gunakan untuk menyimpan data untuk ditampilkan ke tabel

package tiket;

import java.util.ArrayList;

/**
*
* @author djavu
*/
public class Data {
public static ArrayList<String> jenisWisata = new ArrayList<>();
public static ArrayList<Integer> ArrSubTotal = new ArrayList<>();
public static ArrayList<Integer> ArrJumlahTiket = new ArrayList<>();
public static ArrayList<String> ArrTanggal = new ArrayList<>();

}
13. Setelah itu kita beralih ke JTP1.java
Desain seperti gambar dibawah

Kemudian dibawah ini ada nama nama pallete yang digunakan beserta variabel nya

14. Isi kodingan JTP1.java seperti dibawah ini.

15. Untuk JTP2.java, JTP3.java, dan EGP.java sama in desain dan kodingan dengan JTP1.java
Cuma bedakan nama paket dan label harga
JTP2

JTP3

EGP

16. Setelah itu kita beralih ke DataPenjualan.java
Pertama Anda harus menambahkan Libraries Apache POI Excel untuk Export data tabel ke file Excel. Caranya download dulu libraries nya di https://www-eu.apache.org/dist/poi/release/bin/poi-bin-4.1.1-20191023.zip
Setelah di download ekstrak file zip nyaMasuk ke netbeans project yang kita buatKlik kanan di Package LibrariesAdd JAR/FolderPilih file .jar yang sudah di download
