Interview Questions of if-else-java

Scenario: Java if-else

Scenario:

You are developing a simple ticket booking system for a movie theater. The system needs to determine the ticket price based on the age of the customer:

If the customer is under 12 years old, the ticket price is ₹100.

If the customer is between 12 and 60 years old (inclusive), the ticket price is ₹200.

If the customer is above 60 years old, the ticket price is ₹150.

Question:

How would you implement this logic using if-else statements in Java? Please write a code snippet and explain your approach.

Answer:

To solve this, I would use an if-else-if ladder to check the customer’s age and assign the correct ticket price:

public class TicketBooking {
    public static void main(String[] args) {
        int age = 65; // Example age
        int ticketPrice;

        if (age < 12) {
            ticketPrice = 100;
        } else if (age <= 60) {
            ticketPrice = 200;
        } else {
            ticketPrice = 150;
        }

        System.out.println("Customer age: " + age);
        System.out.println("Ticket price: ₹" + ticketPrice);
    }
}

Explanation:

The first if checks if the age is less than 12 for the child price.

The else if checks if the age is between 12 and 60 (inclusive) for the standard price.

The else covers customers above 60 for the senior citizen price.

This structure ensures only one block runs, based on the customer’s age.
