Information & Algorithm

Design a class RailwayTicket with 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
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

Member 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 member methods.

Program Code

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

Enter name: Rumman Ansari
Enter coach: First_AC
Enter mobile no: 8641874922
Enter amount: 500
Name: Rumman Ansari
Coach: First_AC
Total Amount: 1200
Mobile number: 8641874922

How to learn from this program

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.

Practice suggestion

After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
