Question

use java thanks

Write a program that prompts a user to enter number of Math question that she wishes the system to generate. The system will random generate Math questions which consisted of ±' , x and / of two positive integer numbers. The sample run programs are depicted as below Sample run 1 How many Math question you want to create? 4 Sample run 2 How many Math question you want to create? 10 4 questions have been created as below: 10 questions have been created as below: 1) 45/87 1) 22 59 2) 21 56 2) 86 61 3) 59 x 95 3) 90/96 4) 29-19 4) 65/37 5) 76-38 6) 35 x 33 7) 94-98 8) 37 x 75 9) 47 x 62 10) 8/1

Answer 1

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Here a new java program with name "Main.java" is created, which contains following code.

Main.java :

import java.util.*;//importing package
import java.util.Random;
public class Main //Main class
{ //main method
   public static void main(String[] args) {
       //creating object of scanner class
       Scanner sc=new Scanner(System.in);
       //asking user to enter number of questions
       System.out.print("How many Math question you want to create? ");
       int num=sc.nextInt();//reading input
       //display details
       System.out.println(num+" questions have been created as below : ");
   //creating object of Random class
   Random random=new Random();
       //using for loop to generate number of questions
       for(int i=1;i<=num;i++)
       {
       int op=random.nextInt(5-1)+1;//this will generate number 1 to 4
       int num1=random.nextInt(100-1)+1;//generate number between 1 to 100
       int num2=random.nextInt(100-1)+1;//generate number between 1 to 100
       //using switch loop to generate operations
       switch(op)
       {
       case 1:System.out.println(i+")"+num1+" + "+num2);
       break;//used to come out of case
       case 2:System.out.println(i+")"+num1+" - "+num2);
       break;//used to come out of case
       case 3:System.out.println(i+")"+num1+" x "+num2);
       break;//used to come out of case
       case 4:System.out.println(i+")"+num1+" / "+num2);
       break;//used to come out of case
       }
       }
   }
}

======================================================

Output : Compile and Run above program to get the screen as shown below

Screen 1 :Main.java,screen asking number of questions

input How many Math question you want to create? 10

Screen 2 :Screen showing questions

input How many Math question you want to create? 10 10 questions have been created as below 1)18 17 2)12 x 8:3 3) 50 56 4) 59 82 5)94 x 76 6)96/4 7)85 65 8)48 x 79 9)796 10)34 - 20 . . Program finished with exit code 0 ss ENTER to exit console

Screen 3 :

How many Math question you want to create? 4 4 questions have been created as below: 1) 50 87 2) 46 - 20 3)34 80 4)76+70 . . Program finished with exit code 0 Press ENTER to exit console
