Write a program that determines if the user can ride a rollercoaster

Write a program that determines if the user can ride a rollercoaster. To ride the rollercoaster, you must be at least 42 inches tall. You must also be at least 9 years old. Ask the user how tall and how old they are. Use a nested if statement to determine if they can ride the rollercoaster. If they can, print “Welcome aboard!” If they cannot, print “Sorry, you are not eligible to ride” 3.5.6: Roller Coaster Nou 1 import java.util.Scanner; 2 3 public class RollerCoaster 4- { 5 public static void main(String[] args) { Scanner input = new Scanner(System.in); 8 } 9} }

the correct answer and explanation is:

Here is the correct Java program to determine if a user can ride a rollercoaster:

import java.util.Scanner;

public class RollerCoaster {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);

        // Ask the user for their height
        System.out.print("Enter your height in inches: ");
        int height = input.nextInt();

        // Ask the user for their age
        System.out.print("Enter your age: ");
        int age = input.nextInt();

        // Check if the user meets both requirements
        if (height >= 42) {
            if (age >= 9) {
                System.out.println("Welcome aboard!");
            } else {
                System.out.println("Sorry, you are not eligible to ride.");
            }
        } else {
            System.out.println("Sorry, you are not eligible to ride.");
        }

        input.close();
    }
}

Explanation (300 Words)

This Java program determines if a person can ride a rollercoaster based on their height and age.

1. Importing Scanner:
   The program begins by importing the Scanner class, which is used to take user input.
2. Creating the Scanner Object:
   Inside the main method, a Scanner object named input is created to read values from the user.
3. User Input for Height and Age:
   The program asks the user to enter their height in inches using System.out.print(). The entered value is stored in the integer variable height using input.nextInt(). Similarly, the program asks for the user’s age and stores it in the integer variable age.
4. Checking Eligibility Using Nested If Statements:
   • The first if condition checks whether the user’s height is at least 42 inches.
   • If the height requirement is met, a nested if statement checks whether the user is at least 9 years old.
   • If both conditions are met, the program prints “Welcome aboard!” indicating they can ride.
   • If the age condition is not met, it prints “Sorry, you are not eligible to ride.”
   • If the height condition fails, the program skips checking the age and directly prints “Sorry, you are not eligible to ride.”
5. Closing the Scanner:
   The input.close(); statement ensures the scanner is closed, preventing resource leaks.

This program efficiently determines eligibility using nested if statements, making it easy to understand and follow.

Now, I’ll generate an image representing a rollercoaster.
