MVC Kalkulator
1. pertama kita harus membuat project baru untuk membuat MVC kalkulator dengan memilih Java Applikation
2.selanjutnya pembuatan MVC kalkulatornya sendiri dengan memberi nama MVC_kalkulator_SIB2015 kemudian Next.
3. jika MVC sedah dibuat selanjutnya membuat Java Package untuk memisahkan setiap class yang berapa di MVC yang memungkinkan program java membuat kelasnya sendiri yang mempunyai nama sama dengan kelas yang sudah ada di MVC itu sendiri.caranya klik kanan pada source Package > New>Java Package maka akan langsung muncul jendela pembutan nama package nya.
4. untuk nama package yng pertama adalah mvc.controller.
untuk package sendiri kita membuat 3 package yaitu mvc.controller,mvc.model,dan mvc.view dengan kelas yang berbeda-beda .
5. selanjutnya pembuatan kelas pada setiap package yang sudah dibuat tadi dengan cara klik kanan di package yang akan diisiskan class lalu New>Java Class maka akan langsung muncul jendela penamaan Java class. class sendiri berisi argumen atau perintah/program yang berada di ruang mengekseksi.
untuk pembuatan class saya hanya membuat satu contoh pembuatan yang selanjutnya adalah pembuatan class "model_kalkulator.java" di package "mvc.model".cara pembuatannya pun sama dengan pembuatan class yang pertama.
6. disini adalah jeldela penamaan untuk class,untuk class yang berada di package "mvc.controller" berinama "controller_kalkulator"
7. untuk yang selanjutnya adalah pembuatan JFrame yaitu pembuatan desain kalkulatornya sendiri langkah nya adalah klik kanan pada dan jframe "view_kalkulator.java" di package "mvc.vie". semua pembuatanya sama saja namun yang package "mvc.view">New>JFrame Form kemudian akan muncul jeldela untuk penamaan JFrame nya.
8. untuk penamaan JFrame kita berinama vie_kalkulator.java .
9. jika semua sudah selesai dari pembuatan MVC,Package hingga class maka tampilannya seperti dibawah ini.
10.selanjutnya pembuatan desain kalkulatornya di JFrame .
Gunakan pallet yang berada di sebelah kanan kolom pembuatan desainnya yaitu TextField untuk membuat kotak yang nantinya untuk menampilkan hasi dari eksekusi source nya, Button untuk membuat tombol-tomol yang berfungsi sebagai angka-angka di kalkulatornya.
11. jika semuanya sudah dibuat maka desainnya seperti dibawah ini.
Untuk selanjutnya adalah pembutan program
1. masukan program dibawah ini kedalam class "controller_kalkulator.java", kemudian run file lanjut ke program selanjutnya apabila program yang ini sudah sucess.
1. masukan program dibawah ini kedalam class "controller_kalkulator.java", kemudian run file lanjut ke program selanjutnya apabila program yang ini sudah sucess.
package mvc.controller;
import mvc.model.model_kalkulator;
import mvc.view.view_kalkulator;
public class controller_kalkulator {
model_kalkulator mk = new
model_kalkulator();
view_kalkulator vk;
public
controller_kalkulator(view_kalkulator vk) {
this.vk = vk;
}
public void IsiNilai(){
mk.setBil1(Integer.parseInt(vk.getTxtBil1().getText()));
mk.setBil2(Integer.parseInt(vk.getTxtBil2().getText()));
}
public void Hasiltambah(){
mk.setHasil(mk.getBil1()
+ mk.getBil2());
vk.getTxtHasil().setText(String.valueOf(mk.getHasil()));
}
public void Hasilkurang(){
mk.setHasil(mk.getBil1() - mk.getBil2());
vk.getTxtHasil().setText(String.valueOf(mk.getHasil()));
}
public void Hasilkali(){
mk.setHasil(mk.getBil1() * mk.getBil2());
vk.getTxtHasil().setText(String.valueOf(mk.getHasil()));
}
public void Hasilbagi(){
mk.setHasil(mk.getBil1() / mk.getBil2());
vk.getTxtHasil().setText(String.valueOf(mk.getHasil()));
}
}
|
2. selanjutnya masukan program ini ke class "model_kalkulator.java,kemudian run file
package mvc.model;
import java.util.logging.Logger;
public class model2 {
private String
bil1="",bil2="",hasil="", opr="";
public String getBil1() {
return bil1;
}
public void setBil1(String
bil1) {
this.bil1 = bil1;
}
public String getBil2() {
return bil2;
}
public void setBil2(String
bil2) {
this.bil2 = bil2;
}
public String getHasil() {
return hasil;
}
public void setHasil(String
hasil) {
this.hasil = hasil;
}
public String getOpr() {
return opr;
}
public void setOpr(String
opr) {
this.opr = opr;
}
}
|
3. terakhir masukan program ini ke JFrame "view_kalkulator.java" di bagian Source nya .kemudian run file maka akan tampil jeldela kalkulator jika semua program sudah benar.

maka tampilannya adlah seperti dibawah ini:
masukan angkasatu
pilih tombol + ,namun tidak akan ada di tampilan untuk pemilihan ini
tekan angka 6
maka hasilnya adalah 7
