Question

Hi.

Intro Java hw help needed;

Update an existing Java program that inputs two integers and outputs their sum, quotient and remainder by adding code to also output the difference and product.

Answer 1

import java.util.*;
import java.lang.*;
import java.io.*;

class Hwk3
{
public static void main (String[] args) throws java.lang.Exception
{
  int integer1,integer2,result,quotient,remainder;
  Scanner stdin=new Scanner(System.in);
  System.out.println("Calculator");
  System.out.println("Enter two Integers");
  integer1=stdin.nextInt();
  integer2=stdin.nextInt();
  System.out.println("Integer1= "+integer1 +"   Integer2= "+integer2);
  System.out.println("Enter Option\n 1. Addition\n 2.Subtraction\n 3. Multiplication\n 4. Division");
  int option=stdin.nextInt();
  switch(option)
  {
   case 1: result=integer1+integer2;
           System.out.println("Addition Of two integers= "+result);
           break;
   case 2: result=integer1-integer2;
           System.out.println("Subtraction Of two integers= "+result);
           break;
   case 3: result=integer1*integer2;
           System.out.println("Multiplication Of two integers="+result);
           break;
   case 4: quotient=integer1/integer2;
           remainder=integer1%integer2;
            System.out.println("Quotient Of two integers= "+quotient);
             System.out.println("Remainder Of two integers= "+remainder);
           break;
   default: System.out.println("Enter the correct choice");
            break;
  }
  
}
}

output
