Part 5

Modify the program from Part 4 to allow the user to pick a type of arithmetic problem to study. An option of 1 means addition problems only, 2 means multiplication problems only, 3 means subtraction problems only, 4 means division problems only and 5 means a random mixture of all these types.

This part modifies part 4, the coding for part 4 is provided below:

import java.security.SecureRandom; import java.util.Scanner;

public class Test { public static void main(String[] args) { Scanner sc = new Scanner(System.in); String flag;

do { // calling quiz quiz(sc); // getting user input about next round System.out.print(" Do you want another round?(yeso): "); flag = sc.next(); System.out.println(); } while (flag.equalsIgnoreCase("yes")); sc.close(); }

public static void quiz(Scanner sc) { SecureRandom rand = new SecureRandom();

int countCorrect = 0;// for count correct answer

int difficulty = readDifficulty(sc); System.out.println();

for (int i = 1; i

int first = generateQuestionArgument(rand, difficulty); int second = generateQuestionArgument(rand, difficulty); int correctAns = first * second;// correct ans

askquestion(first, second, i);

int response = readResponse(sc);

if (isAnswerCorrect(correctAns, response)) { displayCorrectResponse(rand); countCorrect++; } else displayIncorrectResponse(rand); } displayCompletionMessage(countCorrect); }

//generating random number according to given dificulty private static int generateQuestionArgument(SecureRandom rand, int difficulty) { int argument = 0; if (difficulty == 1) argument = rand.nextInt(10); else if (difficulty == 2) argument = rand.nextInt(100); else if (difficulty == 3) argument = rand.nextInt(1000); else argument = rand.nextInt(10000); return argument; }

//reading difficulty from user private static int readDifficulty(Scanner sc) { System.out.print("Enter difficulty level(1-4): "); return sc.nextInt(); }

//calculating percent and displaying completion result private static void displayCompletionMessage(int countCorrect) { double percent = ((double) countCorrect / 10.0) * 100.0; System.out.println(" You Scored: " + percent + "%"); if (percent

private static void displayIncorrectResponse(SecureRandom rand) { String incorrect[] = { "No. Please try again", "Wrong. Try once more", "Don't give up!", "No. Keep trying" };

// generating random index int index = rand.nextInt(incorrect.length);

System.err.println(incorrect[index]); //changing the color to red for incorrect response }

private static void displayCorrectResponse(SecureRandom rand) { String appreciate[] = { "Very good!", "Excellent", "Nice work!", "Keep up the good work!" };

// generating random index int index = rand.nextInt(appreciate.length);

System.out.println(appreciate[index]); }

private static boolean isAnswerCorrect(int correctAns, int response) { return correctAns == response; }

private static int readResponse(Scanner sc) { System.out.print("Ans. "); int response = sc.nextInt(); return response; }

private static void askquestion(int first, int second, int i) { System.out.println("Q." + i + " how much is " + first + " times " + second + "?"); } }

---------------------------------------------------

The program also needs to follow the following ruleset:

The program shall generate random numbers with a SecureRandom object

The program shall ask the student to enter a difficulty level of 1, 2, 3, or 4

A difficulty level of 1 shall limit random numbers to the range of 0-9, inclusive

A difficulty level of 2 shall limit random numbers to the range of 0-99, inclusive

A difficulty level of 3 shall limit random numbers to the range of 0-999, inclusive

A difficulty level of 4 shall limit random numbers to the range of 0-9999, inclusive

The program shall ask the student to enter a problem type of 1, 2, 3, 4, or 5 with an appropriate human-readable label

The program shall ask the student to solve 10 different problems, as determined by the problem type

A problem type of 1 shall limit the program to generating only addition problems

A problem type of 2 shall limit the program to generating only multiplication problems

A problem type of 3 shall limit the program to generating only subtraction problems

A problem type of 4 shall limit the program to generating only division problems

A problem type of 5 shall result questions that are a randomly mixture of addition, multiplication, subtraction, and division problems

Problems shall contain two numbers sampled from a uniform random distribution with bounds determined by the problem difficulty

The program shall display a random positive message if the student provides a correct response

The program shall display a random negative message if the student provides an incorrect response

The program shall display the student's score after the student has attempted to solve 10 problems

The student's score shall be the percentage of problems correctly solved

The program shall display the message "Please ask your teacher for extra help." if the student's score is less than 75%

The program shall display the message "Congratulations, you are ready to go to the next level!" if the student's score is greater than or equal to 75%

The program shall ask the student if they want to solve a new problem set after the score message has been displayed

The program shall restart when the student agrees to solve a new problem set

The program shall terminate when the student declines to solve another problem set

Create a method called "quiz" that contains the program logic

Create a method called "readDifficulty" that reads the difficulty level from the student

Create a method called "readProblemType" that reads the difficulty level from the student

Create a method called "generateQuestionArgument" that uses the difficulty level to generate a random number

Create a method called "askQuestion" that prints the problem to the screen

Create a method called "readResponse" that reads the answer from the student

Create a method called "isAnswerCorrect" that checks to see if the student's answer matches the correct answer to the problem

Create a method called "displayCorrectResponse" that prints out the response when a student enters a correct answer

Create a method called "displayIncorrectResponse" that prints out the response when a student enters an incorrect answer

Create a method called "displayCompletionMessage" that prints out the studen't score and appropriate score response

Create a main method that runs your program by calling the "quiz" method

If you have any questions please leave a comment so I could clarify. Thank you.
