Question

Java

7) Create a method that will be used to test an IQ. This method will receive only a String and a Random object when called, and return an int. In this method you will: create a new Scanner object, say hi to the user by name, get 2 random numbers between 0 and 49, and ask the user what the sum of the 2 numbers is. If the user is correct say "Great Job!", and then assign IQ the value of 100 plus the sum of the 2 numbers. If the user is incorrect, say "No, the answer was...", display the answer, and assign IQ the value of 10 plus the sum of the 2 numbers. Return IQ.

8) When the user enters 2 (in a switch statement), back in the main method, call the method you created in #7, send the user's name and the random object you created as arguments to the method. Display the returned value as the user's IQ.

CODE:-

import java.util.*;

public class HomeworkLib {

    public static void main(String[] args) {

        Random rand = new Random();  // this is random class object

        Scanner sc = new Scanner(System.in);  

        System.out.print("Enter the user name: ");

        String userName = sc.next();  // taking the name input

        System.out.print("Enter 2 to start the IQ game: ");  // asking for user input

        int n = sc.nextInt();

        switch (n) {

            case 2:

                int reuslt = testIQ(userName, rand);  // calling the method with name and random object

                break;

            default:

                System.out.println("try again");

        }

    }

    public static int testIQ(String userName, Random rand) {

        Scanner sc1 = new Scanner(System.in);  // creating the scanner object

        int IQ = 0;

        System.out.println("Hi! " + userName);

        int a = rand.nextInt(49);  // creating values between 0 to 49

        int b = rand.nextInt(49);

        System.out.println("What is the sum of " + a + " and " + b);  //asking for sum

        int sum = sc1.nextInt();

        if (sum == a + b) {

            System.out.println("Great Job!"); // when correct

            IQ = 100 + a + b;

        } else {

            System.out.println("No, the answer wa " + (a + b));  // when wrong

            IQ = 10 + a + b;

        }

        return IQ;

    }

}
