Question

I am learning programming in JAVA. Please help me with this programming assignment.

Your lab assignment this week is to build a little math program to help kids practice their addition and subtraction.

You will create a menu and have the kid select what kind of math problem they want to solve.

Once the kid selects what kind of problem. Randomly generate two numbers, display the problem and allow the kid to enter the answer. If the answer is correct. display a message. If the answer is incorrect, let the kid know the answer is incorrect and display the correct answer.

Requirements:

- use switch...case statements for the menu

- if..then...else statements

- mathematic calculations

- use random class

- once completed please upload your main.java file or paste code

Sample output:

***** Menu *****

1. Addition

2. Subtraction

***************

Enter selection: 1

You selected Addition

1+2 =

Enter answer: 3

You are correct!!!

Answer 1

import java.util.Random;
import java.util.Scanner;

public class RandomAddition {
   public static void main (String args[])
   {
  
       Scanner scan = new Scanner(System.in);

  
   Random r1 = new Random();
   int num1=r1.nextInt(10);
   int num2=r1.nextInt(10);
   int result;
   System.out.print("**********MENU*********\n");
   System.out.println("1. Addition");
   System.out.println("2. Subtraction");
   System.out.println("Enter selection: ");
   int select=scan.nextInt();
     
   //switch case statement
   switch(select)
   {
          case 1:
              result=num1+num2;
              System.out.println("You selected Addition");
              System.out.println(num1+"+"+num2+"= ");
              System.out.print("Enter answer: ");
              int res=scan.nextInt();
              if(res==result)
                  System.out.println("You are correct!!!");
              else
              {
                  System.out.println("Answer is incorrect, correct answer is: "+result);
              }
              break;
          case 2:
              int temp;
              if(num1<num2)
              {
                  temp=num1;
                  num1=num2;
                  num2=temp;
              }
              result=num1-num2;
             
              System.out.println("You selected Subtraction");
              System.out.println(num1+"-"+num2+"= ");
              System.out.print("Enter answer: ");
              res=scan.nextInt();
              if(res==result)
                  System.out.println("You are correct!!!");
              else
              {
                  System.out.println("Answer is incorrect, correct answer is: "+result);
              }
              break;
          default:
              System.out.println("invalid input");
             
   }
