String Handling — Question 32
Back to all questionsQuestion 19
Design a class RailwayTicket with the following description:
Instance Variables/Data Members:
String name: to store the name of the customer.
String coach: to store the type of coach customer wants to travel in.
long mobno: to store customer's mobile number.
int amt: to store basic amount of ticket.
int totalamt: to store the amount to be paid after updating the original amount.
Methods:
void accept(): to take input for name, coach, mobile number and amount.
void update(): to update the amount as per the coach selected.
Extra amount to be added in the amount as follows:
| Type of coaches | Amount |
|---|---|
| First_AC | 700 |
| Second_AC | 500 |
| Third_AC | 250 |
| Sleeper | None |
void display(): To display all details of a customer such as name, coach, total amount and mobile number.
Write a main() method to create an object of the class and call the above methods.
import java.util.Scanner;
public class RailwayTicket
{
private String name;
private String coach;
private long mobno;
private int amt;
private int totalamt;
private void accept() {
Scanner in = new Scanner(System.in);
System.out.print("Enter name: ");
name = in.nextLine();
System.out.print("Enter coach: ");
coach = in.nextLine();
System.out.print("Enter mobile no: ");
mobno = in.nextLong();
System.out.print("Enter amount: ");
amt = in.nextInt();
}
private void update() {
if(coach.equalsIgnoreCase("First_AC"))
totalamt = amt + 700;
else if(coach.equalsIgnoreCase("Second_AC"))
totalamt = amt + 500;
else if(coach.equalsIgnoreCase("Third_AC"))
totalamt = amt + 250;
else if(coach.equalsIgnoreCase("Sleeper"))
totalamt = amt;
}
private void display() {
System.out.println("Name: " + name);
System.out.println("Coach: " + coach);
System.out.println("Total Amount: " + totalamt);
System.out.println("Mobile number: " + mobno);
}
public static void main(String args[]) {
RailwayTicket obj = new RailwayTicket();
obj.accept();
obj.update();
obj.display();
}
}Output
Key Concepts Covered
