Question

Implement a Java program that creates math flashcards for elementary grade students. User will enter his/her name, the type (+, -, *, /), the range of the factors to be used in the problems, and the number of problems to work. The system will provide problems, evaluate user responses to the problems, score the problems, and provide statistics about the session at the end. Functional Requirements
• User enters name at the beginning of a session. • System covers four math operations – addition, subtraction, multiplication, and division – with the user choosing which of the four operations to do in the session. Only 1 type of problem can be done in each session. • User will enter additional session parameters from prompts – number of problems to work and the range of values desired in the problems, e.g., addition with factors ranging from 0 to 12. • System will present problems to the user. • User will respond to problems with an answer and the system will provide im

import java.util.Scanner;

       Scanner scan = new Scanner(System.in);

       System.out.print("Enter you name: ");

       String name = scan.nextLine();

       System.out.print("Enter your operation (+,-,*,/): ");

       String operator = scan.nextLine();

I hope this helps!
