Java Programming: Loops and Conditionals

Laura Brown teaches 3rd grade. She and her students would like a computer program to practice multiplication. Laura would like the students to practice on random multiplication questions based on random numbers between 1 and 10. Laura would also like the student to be able to pick the number of questions that the program will ask.

import java.util.Scanner; import java.util.Random; public class Main { public static void main(String[] args) { Scanner input = new Scanner(System.in); Random rand = new Random(); System.out.print("Enter number of questions you wish to practice: "); int n = input.nextInt(); int i = 1; while(i <= n){ int num1 = 1 + rand.nextInt(10); int num2 = 1 + rand.nextInt(10); int answer = num1 * num2; System.out.print("Question " + i + ": " + num1 + " x " + num2 + " = "); int response = input.nextInt(); if(response == answer){ System.out.println("Correct answer!"); } else{ System.out.println("Wrong answer. It should be " + answer); } i++; } } }

Explanation:

Firstly, we import Scanner and Random classes (Line 1-2) as we need to get user input for number of questions and generate random number in each question.

Next, create a Scanner and Random object (Line 7-8). Prompt user to input number of question and get the input using the Scanner object (Line 10-11).

Next create a while loop and set the condition to loop for n number of times (based on number of questions) (Line 14). In the loop, use Random object nextInt method to generate two integers between 1 -10 (Line 15-16). Prompt user to input an answer using the Scanner object (Line 18-19). If the response is matched with answer print a correct message (Line 21-22) other wise inform user they write a wrong answer and show the correct answer (Line 24-25).

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed
