Masalah Display Harga.

[freakery 0]

Ok, ini salah satu kerja yang diberikan oleh lecturer aku. Setelah habis program coding java ni, aku rasa macam nak letak lagi satu fungsi. Soalan aku, macam mana kah nak display confirmation harga?

Rujuk output, kira macam bila kita pilih nombor 1. Standard room, dia akan papar harga, dan confirmation 1.Yes 2.No.

Setakat ni, apa yang aku buat adalah kiraan secara automatik.

import java.io.*;
class Room
{
public static void main (String args[])throws IOException
{
BufferedReader input=new BufferedReader (new InputStreamReader(System.in));
System.out.println("**************************************************");
System.out.println("\t\t\t\tHOTEL LANGKAWI INN\n");
System.out.println("\t\t65,JALAN PANDAK MAYAH,KUAH LANGKAWI\n");
System.out.println("\t\t TEL:04-5678900\t\tFAX:04-5678901\n");
System.out.println("\n********************ROOM TYPE*********************\n");
System.out.println("\t\t\t\t1:STANDARD ROOM");
System.out.println("\t\t\t\t2:DELUXE ROOM");
System.out.println("\t\t\t\t3:EXECUTIVE ROOM\n");
int room,day;
double price,discount,totalDiscount,totalPrice;
double balance=0;
double result=0;
double payment=1100;
System.out.print("\t\t\t\tYour Room Type:");
room=Integer.parseInt(input.readLine());
System.out.print("Staying For (Days):");
day=Integer.parseInt(input.readLine());
System.out.println("\n");
switch(room)
{
case 1:
price=100;
discount=(0.05);
totalDiscount=(price)*(discount);
totalPrice=(price)-(totalDiscount);
result=(day)*(totalPrice);
balance=(payment)-(result);
break;
case 2:

Eeee.. dah lama tk buat task Java zaman belajar.. time belajar dulu, siyes aku tk reti nak buat.
Sekarang aku main buat asalkan jalan...
Aku kasi bulat2... masih tak propernyer cara.. tapi asalkan jalan la dulu. Lepas nih anda boleh inject lagi..
kasi masuk deposit cash. instead buat constant 1100 tuh.
Anda dah ada basic yang kuat. So mesti boleh pahamn start belajar dari code orang.
