           }
       }
       System.out.println("The total you got correct is: " + correct);
       System.out.println("The total you got incorrect is: " + incorrect);
   }
}

how do i make another class that contains the questions, a constructor, accessor methods, and anything else needed to make program run?

Answer 1

Please find the code below:

QuestionGenerator.java

package classes5;

import java.util.ArrayList;

public class QuestionGenerator {

ArrayList<String> questions;

ArrayList<String> answers;

QuestionGenerator(){

questions = new ArrayList<String>();

questions.add("Which of the following is considered an input device?\n"

+ "(a)Speakers\n(b)Printer\n(c)Central Processing Unit\n(d)Keyboard");

questions.add("What variable is Legal in Java?\n"

+ "(a)dayOfWeek\n(b)3dGraph\n(c)mixture#3\n(d)week day\n");

questions.add("What is the purpose of the binary logical operators, && and ||,"

+"that java provides?\n"

+"(a)marks beginning of a comment\n(b)combines two boolean expressions into a single expression\n"

+"(c)indicates end of a statement\n(d)causes a backslash to be printed");

answers = new ArrayList<String>();

answers.add("d");

answers.add("a");

answers.add("b");

}

void welcomeMessage(){

System.out.println("My name is Danielle Brandt. "

+"This is a quiz program that will test your JAVA knowledge"

+"with multiple choice questions!\n\n");

System.out.println("Lets start the quiz!\n\n");

}

String getQuestionNumber(int i){

return questions.get(i);

}

int getQuestionSize(){

return questions.size();

}

String getAnswerNumber(int i){

return answers.get(i);

}

}

P3A2_BRANDT_4005916.java

package classes5;

import java.util.Scanner;

import java.util.ArrayList;

public class P3A2_BRANDT_4005916

{

public static void main(String[] args)

{

String name;

int correct = 0;

int incorrect = 0;

Scanner phantom = new Scanner(System.in);

System.out.println("Hello, What is your name?");

name = phantom.nextLine();

System.out.println("Welcome " + name + "!\n");

QuestionGenerator tester = new QuestionGenerator();

for(int i = 0; i < tester.getQuestionSize(); i++)

{

System.out.println(tester.getQuestionNumber(i));

String ans = tester.getAnswerNumber(i);

String user = phantom.nextLine();

if(user.equalsIgnoreCase(ans))

{

System.out.println("That is correct!");

correct++;

}

else

{

System.out.println("Sorry, that's incorrect!");

incorrect++;

}

}

System.out.println("The total you got correct is: " + correct);

System.out.println("The total you got incorrect is: " + incorrect);

}

}

output:
