A simple way you can achieve this would be to have a while-loop inside the main loop of your quiz code which checks your input variable value.
Till now, you gained the complete knowledge of Java programming language. So, be ready to test your knowledge with this “Java quiz questions”. Here, we are providing you with some multiple choice questions of Java with answers. This java quiz will help you to brush up Java concepts. Do not forget to check other java quizzes as well from the. So, move to the src/test/java folder and make a right-click on it. Click on New Junit Test Case. And create a JUnit test case following the naming rule conventions. Then click on Finish. The JUnit test case will be created. Here, we have created the JUnit test case as TestDemoClass.java, and we got the following output screen covering the. It is the code/s inside a pair of curly braces. If A=10, then after B=A, the value of B is. It is the characteristics of Java which ensures that a program can go only where it is designed to go and eliminates the possibility of altering system data unintentionally.
They decide to create a login page. Users need to register their details and login before using the application. They need to create a login page where only the registered user can login Create a Java program to help them create a simple model for their application by getting registration details, storing them and verifying the login process.
You would set the initial value of the variable that holds the value of the users input to a default string and check to make sure that you keep asking the user for an input while the value of that input is not equal to your desired inputs of: ['D', 'C', 'B', 'A']
You can achieve this using the logical '&&' (and) operator to check and make sure that if the input is not equal to any of the acceptable input you continue looping for an input. This way each time the user inputs a value, the program does not move on until it sees a recognized input.
Specifically in pseudo-code you would write this:
do {
user_ans[i] = ';
do {
user_ans[i] = USER_INPUT
} while(user_ans[i] != 'D' && user_ans[i] != 'C' && user_ans[i] != 'B' && user_ans[i] != 'A');
continue_main_loop_logic();
} while ()

where to put this piece of code? I have tried but the code stops after printing 1st question. import java.io.*; import java.util.*; import java.util.Scanner; public class Main { static Scanner cin = new Scanner(System.in); public static void main(String[] args) { int correct = 0; int incorrect = 0; int questions = 5; System.out.println('Welcome to the Multiple Choice Quiz! n'); String[][] Ques_Ans = { { 'What is the size of float variable? ', 'n A. 8 bit n B. 16 bit n C. 32 bit n D. 64n', 'C' }, { 'Which one of these is not a primitive data type?
