Question

Problem (Computer Assisted Instruction) The use of computers in education is referred to as Computer Assisted Instruction (CAI). Develop a Java application that can help an elementary school student learn division of two decimal integer numbers. When the application is launched, its behaviour should be like as described: 1. The application should welcome the learner and ask if ready to learn the topic. Assume the application can assist only to learn division of two integer numbers. 2. If the user is ready to learn, then show a question like "what will be the quotient when n1 is divided by n2?" and wait for the response. Both n1 and n2 are randomly generated integer numbers with maximum of two digits, i.e., 0 S number < 100. 3. When the learner enters the response, then the application should get the response and determine whether the response is correct or not. 4. If the response is correct, then appreciate the learner and add 5 to its score. 5. If the response is incorrect, then provide the correct answer along with the question and possibly give some explanation for the correct answer. 6. The application should then ask, “will you like to continue or stop?" 7. If the learner chooses to continue then repeat steps 2-6. 8. If the learner chooses to stop, then the application should display message to appreciate the learner, how many questions tried, how many questions correctly answered, how many incorrectly answered, and score of the learner Notes: Greeting messages (like welcome or thank you if done with learner name are considered more effective than the generic messages like Welcome Muhammad is considered better than Welcome. ii. For random number generation, please use an appropriate method of class Random. (Note that it is a requirement not an option), Requirements withst 1. Develop a Java program with the above specified behaviour. 2. Test your program effectively. Include your testing observation in the submission

Answer 1

import java.util.*;

public class Main
{
   public static void main(String[] args) {
       Scanner sc=new Scanner(System.in);
       System.out.println("Enter your name:");
       String name=sc.nextLine();
       System.out.println("\nWelcome "+name);
       Random random=new Random();
       int n1, n2;
       char input='Y';
       int response;
       int total=0, incorrect=0, correct=0, count=0;
       while(input=='Y' || input=='y'){
       n1=random.nextInt(100);
       n2=random.nextInt(100);
       System.out.println("what will be the quotient when "+n1+
       " is divided by "+n2+"?");
       response=sc.nextInt();
       int answer=n1/n2;
       if(response==answer){
       System.out.println("Well done!! Your answer is correct");
       total+=5;
       correct++;
       }
       else{
       System.out.println("Incorrect answer");
       System.out.println("The correct answer is "+answer);
       incorrect++;
       }
       count++;
       System.out.println("will you like to continue or stop?(enter y or Y to continue)");
       input=sc.next().charAt(0);
       }
       System.out.println("Thank you "+name+" !");
       System.out.println("Questions tried: "+count);
       System.out.println("Incorrect answers: "+incorrect);
       System.out.println("Correct answers: "+correct);
       System.out.println("Total Score: "+total);
      
      
   }
}
