- Penjelasan Program, Flowchart, Souce Code beserta Screen Shoot nya
Laptop merupakan alat elektronik yang dibutuhkan dalam membantu memudahkan aktivitas bekerja dan lain sebagainya. Oleh karena itu banyak pebisnis yang mulai membuka bisnis penjualan Laptop. Namun untuk membuka usaha penjualan Laptop membutuhkan dana yang besar dan memiliki pengetahuan mengenai teknologi agar bisnis dapat maju. Bila terdapat kemauan dan kerja keras maka hal tersebut dapat terwujud. Selain itu, penjualan Laptop perlu menggunakan sistem Komputerisasi agar lebih cepat dan efisien. Berbicara mengenai penjualan, saya mencoba untuk membuat program sederhana untuk penjualan Laptop.
- Flowchart
Berikut ini penjelasan pembuatan program selengkapnya.
- Buat project baru
Untuk membuat program penjualan Laptop, Anda perlu membuat project baru dengan memilih File > New Project untuk membuat sebuah project baru.
Buat class baru dengan cara klik kanan pada package > New > Java class dan buat dua class dengan nama ProgramPenjualanLaptop dan Model_penyimpanan.
Buat script pemrograman java pada class ProgramPenjualanLaptop.

package program.penjualan.laptop;
/**
*
* @author Lutfi_Najmi_STMIK_ERESHA
*/
public class ProgramPenjualanLaptop {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Frame_penjualan_laptop Laund = new Frame_penjualan_laptop();
Laund.setVisible(true);
}
}
Buat script pemrograman java pada class Model_penyimpanan.
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package program.penjualan.laptop;
import javax.swing.table.DefaultTableModel;
/**
*
* @author Ardy Sendleep
*/
public class Model_penyimpanan {
private DefaultTableModel tabel = new DefaultTableModel();
public Model_penyimpanan(){
getTabel().addColumn("No");
getTabel().addColumn("Tipe Laptop");
getTabel().addColumn("Harga Satuan");
}
/**
* @return the tabel
*/
public DefaultTableModel getTabel() {
return tabel;
}
/**
* @param tabel the tabel to set
*/
public void setTabel(DefaultTableModel tabel) {
this.tabel = tabel;
}
}
Buat frame baru dengan cara klik kanan pada package > New > JFrame Form dengan nama Frame_penjualan_laptop.
Buat desain frame seperti contoh dibawah ini.
Buat script pada desain frame dengan cara klik kanan pada button Beli > Events > Actions > ActionPerformed dan buat script pada frame.
