The concept of boolean variables is that; variables declared as boolean type can only take any of two values. The variable can either be true or false. Such variable cannot take any other value apart from these two.
The short quiz program is as follows.
Please note that comments are used to explain difficult lines.
import java.util.*;
public class shortQuiz{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
//This declares the variables that represent correct answers as boolean data type; the variables are also initialized
boolean q1 = true, q2 = false, q3 = true;
//This declares the response to each question as boolean data type
boolean q1response, q2response, q3response;
//This prints the first question
System.out.print("Java is a programming language, true or false? ");
//This gets input for the first response
q1response = input.nextBoolean();
//This prints the second question
System.out.print("Only numbers can be stored by variables in Java, true or false? ");
//This gets input for the second response
q2response = input.nextBoolean();
//This prints the third question
System.out.print("There are only 2 possible values which can be held by a boolean variable, true or false? ");
//This gets input for the third response
q3response = input.nextBoolean();
//This prints your first response, alongside the correct answer to the first question
System.out.println("Question 1 - Your answer: "+q1response+". Correct answer: "+q1);
//This prints your second response, alongside the correct answer to the second question
System.out.println("Question 2 - Your answer: "+q2response+". Correct answer: "+q2);
//This prints your third response, alongside the correct answer to the third question
System.out.println("Question 3 - Your answer: "+q3response+". Correct answer: "+q3);
//The program ends here
}
}
See attached image for program sample run.
The above program initializes the correct answers using boolean variables. The correct answers are then printed, after the user answers the three questions.
