Program Method Menu Restoran
Halo semuanya! Ketemu lagi dengan aku Camila, di blog ini. Pada kesempatan kali ini aku mau membahas mengenai Method, dalam penerapan Method ini aku menggunakan Program Pemesanan Menu di Restoran, didalamnya kita akan membuat program dimana pembeli dapat melihat menu yang tersedia, kemudian dapat mencari menu berdasarkan keyword / kata kunci tertentu. Setelahnya restoran akan mengkalkulasikan pesanan yang dipesan oleh pembeli.
A. Source Code
import java.util.Scanner;
public class method {
static int hitung_pembelian(int harga_satuan, int jumlah)
{
int harga = harga_satuan*jumlah;
return harga;
}
static String[][] sort(String[] menu, int[] harga){
String[][] daftar_menu = new String[10][2];
for (int i = 0; i < menu.length; i++) {
for (int j = 0; j < menu.length-1; j++) {
if(menu[j].compareToIgnoreCase(menu[j+1])>0){
String t=menu[j];
menu[j]=menu[j+1];
menu[j+1]=t;
int h=harga[j];
harga[j]=harga[j+1];
harga[j+1]=h;
}
}
}
for (int i = 0; i < menu.length; i++) {
daftar_menu[i][0] = menu[i];
daftar_menu[i][1] = String.valueOf(harga[i]);
}
return daftar_menu;
}
static String[][] search(String[] menu,int harga[], String cari){
String[][] hasil=new String[10][2];

for (int i = 0; i < menu.length; i++) {
if (menu[i].indexOf(cari)>=0) {
hasil[idx][0]=menu[i];
hasil[idx][1]=String.valueOf(harga[i]);
