Java LRT Station.

[acjfcyber14]

Hello po! Bago lang po ko dito so I'm asking for help of making LRT Station using Array on Java. Clearly I was assigned to do LRT1 Station so right now I'm having a problem of doing the fare pricing.

Example: Current Station ko is: Monumento
Destination is hanggang Baclaran.

Then the price will show up
then the ticket kung ilan gusto mong bilhin na ticket
then the user will input the money and the total change.

Here's the code:

import java.util.Arrays;
import java.util.*;

public class LRTTicket{
public static void main(String[] args){
String lrtArray[] = { "Roosevelt", "Balintawak", "Monumento", "Fifth Avenue", "R. Papa", "Abad Santos", "Blumentritt", "Tayuman", "Bambang", "Doroteo Jose", "Carriedo",
"Central Terminal", "United Nations", "Pedro Gil", "Quirino", "Vito Cruz", "Gil Puyat", "Libertad", "Edsa", "Baclaran" };
int payment;
int ticket;
int total;
Scanner station = new Scanner(System.in);

System.out.print("Enter a station: ");
lrtArray[0] = station.nextLine();

System.out.print("Enter destination: ");
lrtArray[1] = station.nextLine();

switch(lrtArray[1]){
case "Roosevelt":
System.out.println("P15");
System.out.print("Please enter your payment: ");
payment = station.nextInt();
if(payment >= 15){
System.out.println("Here you go.");
payment = payment - 15;
System.out.print("Your change is: " +payment);
} else {
System.out.print("Not enough money to buy this ticket.");
}
break;
case "Balintawak":
System.out.println("P15");
System.out.print("Please enter your payment: ");

P.S Pabago bago kasi ako ng code pero eto ung una kong ginawa.

Patulong nalang po. Salamat po

HELLO, ETO YUNG GINAWA KONG SOLUTIONS SA PROBLEM MO. MAY ILANG COMMENTS JAN FOR CLARIFICATION PERO TRY TO UNDERSTAND PARIN. BINIGAY KO NA SAYO SAMPLE CODE, IKAW NA BAHALA UMINTINDI NG LOGIC . NAPAKAHABA KASI NUNG GINAWA MO, SAKIT SA MATA HAHAHAHA

============================================================
Scanner scan = new Scanner(System.in);
String[] stations = new String[] {"A","B","C","D","E"};
int[] fare = new int[] {10,20,30,40,50};
int payment; int total; int number_of_tickets;
int starting_index = 0; int destination_index = 0;
String starting_point; String destination_point;

System.out.println("Enter Starting");
starting_point = scan.nextLine();
System.out.println("Enter Destination");
destination_point = scan.nextLine();
System.out.println("How many tickets?:");
number_of_tickets = scan.nextInt();

//for getting the array index of starting and destination
for(int x = 0 ; x<stations.length ; x++){
if(starting_point.equalsIgnoreCase(stations[x])){
starting_index = x;
}
if(destination_point.equalsIgnoreCase(stations[x])){
destination_index = x;
}
}

//for getting the fare and for making payment
if(starting_index > destination_index){
total = fare[(starting_index - destination_index)-1] * number_of_tickets;
System.out.println("Total is: "+total);
System.out.println("Enter your payment: ");
payment = scan.nextInt();
if(payment >= total){
System.out.println("The change is: "+(payment-total));
}else{
System.out.println("Insufficient Funds");
}
}else{
total = fare[(destination_index - starting_index)-1] * number_of_tickets;
System.out.println("Total is: "+total);
System.out.println("Enter your payment: ");
payment = scan.nextInt();
if(payment >= total){
System.out.println("The change is: "+(payment-total));
}else{
System.out.println("Insufficient Funds");
}
}

================================================================
KUNG MAPAPANSIN MO, LIMA LANG YUNG STATIONS NA NILAGAY KO. YUNG ARRAY FOR FARE, YAN YUNG BAYAD DEPENDE SA DISTANCE. KUNWARI YUNG STARTING AY A AT ANG DESTINATION AY NEXT STATION LANG (B). THE VALUE OF THE TICKET IS FARE[0] SINCE MAGKASUNOD LANG. IKAW NA BAHALA UMINTINDI. HAPPY CODING BROTHER, STUDY HARD HAHA

Split into 3 classes. Main, LrtUserInput and LtrTransaction. This is just based on my assumptions.

Pwede mo ma try ang sample code dito.
