I am having small problems in my exercise of data. Here is the topic:
1.Input data Allow a user to input booking item. When running, the screen looks like:
Enter bus code: Enter customer code: Enter number of seats to be booked:After the user enter bcode and ccode, the program check and acts as follows:
- If bcode not found in the Bus list or ccode not found in the customer list then data is not accepted.
- If both bcode and ccode are found in the booking list then data is not accepted.
- If bcode and ccode found in Buses and customers lists but booked = seat then inform the user that the bus is exhausted.
- If bcode or ccode found and in the Bus list booked < seat and k is the entered seat then if k <= seat - booked then data is accepted and added to the end of the Booking list.
Somebody help me. please! < My problem is class BookingList - Booking input and maybe you can use function searchByCode >
Here is my code:
public class Booking {
Customer c;
Bus b;
public Booking() {
}
public Booking(Customer c, Bus b) {
this.c = c;
this.b = b;
}
}
public class Bus {
public String bCode;
public String bName;
public int seat;
public int booked;
public double departTime;
public double arrivalTime;
public Bus() {
}
public Bus(String bCode, String bName, int seat, int booked, double departTime, double arrivalTime) {
this.bCode = bCode;
this.bName = bName;
this.seat = seat;
this.booked = booked;
this.departTime = departTime;
this.arrivalTime = arrivalTime;
}
public double travelTime() {
double result = 0;
result = this.arrivalTime - this.departTime;
return result;
}
@Override
public String toString() {
return " " + bCode + "\t\t" + bName + "\t\t" + seat + "\t\t" + booked + "\t\t" + departTime + "\t\t" + arrivalTime;
}
}
public class Customer {
public String cCode;
public String cName;
public int phone;
public Customer() {
}

this.cCode = cCode;
this.cName = cName;
this.phone = phone;
}
public void displayInfoCustomer() {
System.out.printf("%-15s %-15s %-10s\n", cCode, cName, phone);
}
@Override
public String toString() {
return " " + cCode + "\t\t" + cName + "\t\t" + phone;
}
}
