Menghitung 2 Buah Angka Dengan Menggunakan MVC
1. Buat sebuah project baru. Misalnya adalah LatMVC
2.Buat 2 buah file Java Class pada package yang tersedia. Caranya yaitu klik kanan pada package lalu pilih New lalu pilih Java Class. Untuk nama filenya, misalnya adalah Controller dan Model
Setelah Java Class dibuat, buat sebuah file JForm dengan nama View
Maka projectnya akan menjadi seperti ini
3.. Yang pertama buka file Controller, lalu tambahkan baris dibawah ini, dibawah nama class
private Model mk = new Model();
private View vk;
private View vk;
Setelah itu pilih Constructor
Pada Generate Constructor, centang vk : View lalu klik Generate
Maka akan muncul baris ini secara otomatis
5. Setelah itu tambahkan baris ini dibawah method sebelumnya
public void Jumlah() {
mk.Proses(Integer.parseInt(vk.txtBil1.getText()), Integer.parseInt(vk.txtBil2.getText()));
vk.txtHasil.setText(String.valueOf(mk.Hasil()));
}
6. Maka untuk keseluruhan untuk Controller adalah sebagai berikutmk.Proses(Integer.parseInt(vk.txtBil1.getText()), Integer.parseInt(vk.txtBil2.getText()));
vk.txtHasil.setText(String.valueOf(mk.Hasil()));
}
package latmvc;
public class Controller {
private Model mk = new Model();
private View vk;
public Controller(View vk) {
this.vk = vk;
}
public void Jumlah() {
mk.Proses(Integer.parseInt(vk.txtBil1.getText()), Integer.parseInt(vk.txtBil2.getText()));
vk.txtHasil.setText(String.valueOf(mk.Hasil()));
}
}
7. Setelah file Controller selesai dibuat, selanjutnya yaitu membuat pada file Model. Pada file model, edit dan tambahkan baris ini dibawah nama class
public void Proses(int Bil1, int Bil2) {
this.Bil1=Bil1;
this.Bil2=Bil2;
}
8. Setelah itu buat method baru. Sintaksnya yaituthis.Bil1=Bil1;
this.Bil2=Bil2;
}
public int Hasil () {
Hasil = Bil1 + Bil2;
return Hasil;
}
9. Untuk keseluruhan script Model yaituHasil = Bil1 + Bil2;
return Hasil;
}
package latmvc;
/**
*
* @author Radea
*/
public class Model {
private int Bil1=0, Bil2=0, Hasil=0;
public void Proses(int Bil1, int Bil2) {
this.Bil1=Bil1;
this.Bil2=Bil2;
}
public int Hasil () {
Hasil = Bil1 + Bil2;
return Hasil;
}
}
10. Pada View pertama yang perlu dilakukan adalah mendesign tampilannya.
Untuk nama variabel yaitu txtBil1 untuk text field Angka 1, txtBil2 untuk text field Angka 2, btnProses untuk button + dan txtHasil untuk text field Hasil
11. Setelah itu, pindah ke source code. Pada source, tambahkan baris ini dibawah nama package
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JTextField;
12. Lalu tambahkan bari ini dibawah nama classimport javax.swing.JLabel;
import javax.swing.JTextField;
Controller ck;
13. Tambahkan pula bari ini
public View() {
initComponents();
ck=new Controller(this);
}
14. Lalu buat ActionPerformed pada button + dan tambahkan baris iniinitComponents();
ck=new Controller(this);
}
ck.Jumlah();
15. Setelah itu buat semua komponen berikut ini yang sebelumnya private menjadi public
klik kanan pada komponen yang akan diubah, misalnya adalah button + (btnProses), lalu pilih Properties dan akan muncul jendela Properties seperti ini
Lalu pilih Code. Setelah itu pilih Variabel Modifiers, pada Access ubah private mejadi public
Lalu klik OK dan Close.
16. klik kanan lalu pilih Run. atau bisa dengan menekan Shift+F6. Maka hasilnya akan menjadi seperti ini
n
bbKalkulator Dengan Menggunakan MVC
1. buat sebuah project baru dengan nama Calculator.
Lalu buat, package baru dengan nama calculator dan buat sebuah file Java Class dengan nama Main.
Lalu buat package lain dengan nama model dan dalam package model buat sebuah file Java Class dengan nama CalculatorModel.
Setelah itu buat package baru lagi dengan nama view dan dalam package tersebut buat JFrame Form dengan nama CalculatorView.
Maka dalam project ini akan terdapat 3 package dengan masing-masing 1 file di dalam package.
2. Setelah itu buka file Main dan tambahkan baris ini dibawah nama package
import view.CalculatorView;
Baris ini digunakan untuk meng-import-kan file CalculatorView yang ada dalam package view3. Dan tambahkan pula baris ini dibawah method main
new CalculatorView().setVisible(true);
4. Maka untuk keseluruhan sintaks Main adalah
package calculator;
import view.CalculatorView;
/**
*
* @author radea
*/
public class Main {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
new CalculatorView().setVisible(true);
}
}
5. Setelah itu buka file CalculatorModel dan tambahkan script ini dibawah nama class
int operator=0;
double operand1;
double operand2;
double result;
6. Tambahkan pula script inidouble operand1;
double operand2;
double result;
public void setOperator(int operator) {
this.operator = operator;
}
public double getResult() {this.operator = operator;
}
return result;
}
public void setResult(double hasil) {
this.result = hasil;
}
public void process(){
switch (operator){
case 1:
result = operand1 + operand2;
break;
case 2:
result = operand1 – operand2;
break;
case 3:
result = operand1 * operand2;
break;
case 4:
result = operand1 / operand2;
break;
}
operand1=result;
}
7. Maka keseluruhan script CalculatorModel adalah
package model;
/**
*
* @author radea
*/
public class CalculatorModel {
int operator=0;
double operand1;
double operand2;
double result;
public void setOperand(String opr) {
if(!opr.equals("")){
if(operator==0){
operand1=Double.valueOf(opr);
}else{
operand2=Double.valueOf(opr);
}
}
}
public void setOperator(int operator) {
this.operator = operator;
}
public double getResult() {
return result;
}
public void setResult(double hasil) {
this.result = hasil;
}
public void process(){
switch (operator){
case 1:
result = operand1 + operand2;
break;
case 2:
result = operand1 - operand2;
break;
case 3:
result = operand1 * operand2;
break;
case 4:
result = operand1 / operand2;
break;
}
operand1=result;
}
}
8. Setelah itu buka CalculatorView dan buat design untuk tampilan seperti ini
9. Untuk keseluruhan script CalculatorView adalah
package view;
import java.text.DecimalFormat;
import javax.swing.JOptionPane;
import model.CalculatorModel;
/**
*
* @author radea
*/
public class CalculatorView extends javax.swing.JFrame {
/** Creates new form CalculatorView */
public CalculatorView() {
initComponents();
}
CalculatorModel model = new CalculatorModel();
String operand="";
public void getOperand(javax.swing.JButton button){
operand+=button.getText();
model.setOperand(operand);
resultLabel.setText(operand);
}
private void getOperator(int opt){
model.setOperator(opt);
operand="";
}
private void process(){
DecimalFormat df = new DecimalFormat("#,###.########");
model.process();
operand = "";
resultLabel.setText(df.format(model.getResult())+"");
