Program Parkir Sederhana Menggunakan Java NetBeans

1. Deskripsi
Saat ini cukup banyak pusat perbelanjaan, kantor, ruko atau yang lainnya menggunakan sistem komputerisasi untuk proses parkir. Proses parkir yang semakin canggih dengan bantuan sistem komputer, memudahkan pemilik untuk memanajemen parkir dengan baik. Selain manajemen parkir yang baik, keamanan dalam parkir terjamin karena kendaraan yang masuk maupun keluar telah tercatat dalam database sistem parkir. Kemudahan ini yang menyebabkan semakin banyak pusat perbelanjaan atau yang lainnya menggunakan sistem komputerisasi untuk memanajemen parkir. Petugas parkir hanya melakukan input no kendaraaan dan jam masuk maka pengunjung akan mendapatkan resi parkir yang nantinya diberikan pada petugas ketika ingin keluar dari area parkir. Terinspirasi dari hal tersebut, Kami ingin mencoba membuat sebuah program parkir sederhana menggunakan Java NetBeans. Program ini cukup sederhana karena hanya menampilkan input data seperti: no kendaraan, jenis kendaraan, harga parkir, jam masuk, lama parkir dan total bayar. Program ini dibuat untuk menambah informasi dan tidak dapat diterapkan pada perusahaan atau yang lainnya secara langsung karena membutuhkan banyak penambahan pada program tersebut. Berikut ini akan Kami jelaskan cara membuat program parkir sederhana menggunakan Java NetBeans:

4. Source Code & Tutorial

Bukalah Java NetBeans dan selanjutnya buat project baru dengan memilih File > New Project.

Buat class dengan cara klik kanan pada package > New > Java class dan buat class dengan nama AplikasiParkirSederhana.

Bila class telah dibuat, selanjutnya membuat script pada AplikasiParkirSederhana. Berikut ini contoh script class AplikasiParkirSederhana yang telah selesai dibuat.

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

/**
*
* @author Lutfi_Najmi_STMIK_ERESHA
*/
public class AplikasiParkirSederhana {

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
Frame_Aplikasi_Parkir Laund = new Frame_Aplikasi_Parkir();
Laund.setVisible(true);
}

}

Desain frame untuk tampilan program dengan cara klik kanan pada package > New > JFrame Form dengan nama Frame_Aplikasi_Parkir.

Lakukan pembuatan desain frame program parkir sedehana seperti berikut ini.

Bila desain telah selesai di buat, selanjutnya membuat script java seperti berikut ini.

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

/**
*
* @author Lutfi_Najmi_STMIK_ERESHA

public class Frame_Aplikasi_Parkir extends javax.swing.JFrame {

/**
* Creates new form Frame_Aplikasi_Parkir
*/
public Frame_Aplikasi_Parkir() {
initComponents();
}

/**
* This method is called from within the constructor to initialize the form.
* WARNING: Do NOT modify this code. The content of this method is always

3. Lihat hasil program

Langkah terakhir adalah menjalankan program dengan memilih Run Main Project(F6) atau Pilih Project > Klik kanan > Run. Selanjutnya akan muncul program yang telah Anda buat. Pada program ini, Anda dapat melakukan input no kendaraan, jenis kendaraan, harga tiket, jam masuk, lama parkir. Bila data telah selesai diinput, pilih button proses maka akan muncul total biaya yang harus dibayar.
