Contoh Program Penjualan Menggunakan Java NetBeans

2017-10-17T06:09:00.002-07:00

Selamat datang pengunjung Seputar Programing ini blog adalah anak dari blog Syntax404 seperti yang ada di deskripsi ini adalah blog tentang, berita, code code, maupun tutorial programing.
Baik mungkin itu saja pembukaan yang ingin saya ucapkan di sini.

Oke kita lanjutkan saja tentang artikel "Contoh Program Penjualan Menggunakan Java NetBeans" Dimana jaman semakin canggih dari tahun ke tahun apa apa semua memakai sistem komputer mulai dari program sampai ke database pun memakai komputer, Seperti yang kita ketahui bahwa sebuah bisnis di era digital kini semakin naik naik nya apa apa mau serba instan kayak mie instan saja heheheh... Dalam proses penjualan perlu adanya bukti transaksi yang digunakan untuk merekam semua kegiatan penjualan. Setiap proses transaksi dibutuhkan program untuk mencatat setiap transaksi penjualan sehingga proses lebih cepat. Terinspirasi dari hal tersebut, Saya mencoba membuat program transaksi penjualan menggunakan Java NetBeans. Program ini cukup sederhana dan semoga dapat membantu dalam proses penyimpanan data transaksi penjualan.

Buat project baru

Jalankan software Java NetBeans dan membuat sebuah project baru dengan memilih File > New project > buat nama project Penjualan.

Selanjutnya Anda dapat membuat class dengan cara Klik kanan pada package > New > Java class dan buat 3 class dengan nama, seperti: ModelBarang, ModelPenjualan dan Penjualan.

Buat script pada class ModelBarang seperti berikut ini.

/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package penjualan;

/**
*
* @author user
*/
public class ModelBarang {
private String namaBarang;
private String satuan;
private double harga;

public ModelBarang(String namaBarang, String satuan, double harga) {
this.namaBarang = namaBarang;
this.satuan = satuan;
this.harga = harga;
}

@Override
public String toString() {
return this.namaBarang;
}

/**
* @return the namaBarang
*/
public String getNamaBarang() {
return namaBarang;
}

/**
* @param namaBarang the namaBarang to set
*/
public void setNamaBarang(String namaBarang) {
this.namaBarang = namaBarang;
}

/**
* @return the satuan
*/
public String getSatuan() {
return satuan;
}

/**
* @param satuan the satuan to set
*/
public void setSatuan(String satuan) {
this.satuan = satuan;
}

/**
* @return the harga
*/
public double getHarga() {
return harga;
}

/**
* @param harga the harga to set
*/
public void setHarga(double harga) {
this.harga = harga;
}

}

Buat script pada class ModelPenjualan seperti berikut ini.

/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package penjualan;

import javax.swing.table.DefaultTableModel;

/**
*
* @author master
*/
public class ModelPenjualan {
private double subTotal=0;
private double ppn=0;
private double total=0;
private DefaultTableModel tabel = new DefaultTableModel();

public ModelPenjualan(){
getTabel().addColumn("Barang");
getTabel().addColumn("Harga");
getTabel().addColumn("Qty");
getTabel().addColumn("Satuan");
getTabel().addColumn("Jumlah");
}

public double countSubtotal(){
subTotal=0;
for (int i=0;i<tabel.getRowCount();i++){
subTotal=subTotal+Double.parseDouble(tabel.getValueAt(i, 4).toString());
}
return subTotal;
}

public double countPPN(){
ppn=subTotal*0.1;
return ppn;
}

public double countTotal(){
total=subTotal+ppn;
return total;
}
/**
* @return the subTotal
*/
public double getSubTotal() {
return subTotal;
}

/**
* @param subTotal the subTotal to set
*/
public void setSubTotal(double subTotal) {
this.subTotal = subTotal;
}

/**
* @return the ppn
*/
public double getPpn() {
return ppn;
}

/**
* @param ppn the ppn to set
*/
public void setPpn(double ppn) {
this.ppn = ppn;
}

/**
* @return the total
*/
public double getTotal() {
return total;
}

/**
* @param total the total to set
*/
public void setTotal(double total) {
this.total = total;
}

/**
* @return the tabel
*/
public DefaultTableModel getTabel() {
return tabel;
}

/**
* @param tabel the tabel to set
*/
public void setTabel(DefaultTableModel tabel) {
this.tabel = tabel;
}
}

Untuk menghubungkan antara class dan desain frame Anda dapat membuat script pada class Penjualanseperti berikut ini.

/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package penjualan;

/**
*
* @author user
*/
public class Penjualan {

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
UIPenjualan penjualan = new UIPenjualan();
penjualan.setVisible(true);
}
}

Buat desain Frame untuk tampilan program Anda dengan cara Klik kanan pada package > New > JFrame Form > buat nama frame UIPenjualan.

Buat desain frame UIPenjualan.

Buat script pada desain frame UIPenjualan seperti berikut ini.

/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package penjualan;

import java.awt.event.KeyEvent;
import java.text.NumberFormat;
import javax.swing.table.TableColumn;

/**
*
* @author user
*/
public class UIPenjualan extends javax.swing.JFrame {
ModelBarang barang;
ModelPenjualan penjualan=new ModelPenjualan();

/**
* Creates new form UIPenjualan
*/
public UIPenjualan() {
initComponents();
fillComboBarang();
tblBarang.setModel(penjualan.getTabel());

}

private void fillComboBarang(){
ModelBarang barang1 = new ModelBarang("Susu", "Kaleng", 11000);
ModelBarang barang2 = new ModelBarang("Rokok", "Bungkus", 16000);
ModelBarang barang3 = new ModelBarang("Snack", "Bungkus", 6500);
ModelBarang barang4 = new ModelBarang("Sabun", "Batang", 2000);

cboBarang.addItem(barang1);
cboBarang.addItem(barang2);
cboBarang.addItem(barang3);
cboBarang.addItem(barang4);
}
