Learn this program step-by-step with algorithm, source code, output and detailed explanation.
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.
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();
}
}

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
