Write a Java program to print the sum (addition), multiply, subtract, divide and remainder of two numbers.

Test Data:
Input first number: 125
Input second number: 24

Java: Print the sum, multiply, subtract, divide and remainder of two numbers

Sample Solution-1

Java Code:

public class Exercise6 {
 
 public static void main(String[] args) {
  // Create a Scanner object to read input from the user
  Scanner in = new Scanner(System.in);
   
  // Prompt the user to input the first number
  System.out.print("Input first number: ");
  // Read and store the first number
  int num1 = in.nextInt();
   
  // Prompt the user to input the second number
  System.out.print("Input second number: ");
  // Read and store the second number
   
  // Calculate and print the sum of the two numbers
  System.out.println(num1 + " + " + num2 + " = " + (num1 + num2));
   
  // Calculate and print the difference of the two numbers
  System.out.println(num1 + " - " + num2 + " = " + (num1 - num2));
   
  // Calculate and print the product of the two numbers
  System.out.println(num1 + " x " + num2 + " = " + (num1 * num2));
   
  // Calculate and print the division of the two numbers
  System.out.println(num1 + " / " + num2 + " = " + (num1 / num2));
 
  // Calculate and print the remainder of the division of the two numbers
  System.out.println(num1 + " mod " + num2 + " = " + (num1 % num2);
 }
}

Explanation:

In the exercise above -

It takes two integer numbers as input from the user using the Scanner class.

Scanner in = new Scanner(System.in);
System.out.print("Input first number: ");
int num1 = in.nextInt();
System.out.print("Input second number: ");

System.out.println(num1 + " + " + num2 + " = " + (num1 + num2)); - It calculates and displays the sum of the two numbers.
System.out.println(num1 + " - " + num2 + " = " + (num1 - num2)); - It calculates and displays the difference between the two numbers.
System.out.println(num1 + " x " + num2 + " = " + (num1 * num2)); - It calculates and displays the product of the two numbers.
System.out.println(num1 + " / " + num2 + " = " + (num1 / num2)); - It calculates and displays the result of dividing the first number by the second number.
System.out.println(num1 + " mod " + num2 + " = " + (num1 % num2)); - It calculates and displays the remainder (modulus) when the first number is divided by the second number.

Sample Output:

Input first number: 125                                                                                        
Input second number: 24                                                                                        
125 + 24 = 149
125 - 24 = 101
125 x 24 = 3000
125 / 24 = 5
125 mod 24 = 5

Sample Solution-2

Java Code:

import java.util.Scanner;

public class Main {
 public static void main(String[] args) {
  // Create a Scanner object to read input from the user
  Scanner scanner = new Scanner(System.in);
  
  // Prompt the user to input the first number
  System.out.println("Input the first number: ");
  
  // Read and store the first number
  int n1 = scanner.nextInt();
  
  // Prompt the user to input the second number
  System.out.println("Input the second number: ");
  
  // Read and store the second number
  
  // Calculate the sum of the two numbers
  int sum = n1 + n2;
  
  // Calculate the difference of the two numbers
  int minus = n1 - n2;
  
  // Calculate the product of the two numbers
  int multiply = n1 * n2;
  
  // Calculate the addition of the two numbers (Note: This comment may be a typo; it seems similar to the "sum" calculation)
  int subtract = n1 + n2;
  
  // Calculate the division of the two numbers
  int divide = n1 / n2;
  
  // Calculate the remainder when dividing the two numbers
  int rnums = n1 % n2;
  
  // Display the results of the calculations
  System.out.printf("Sum = %d\nMinus = %d\nMultiply = %d\nSubtract = %d\nDivide = %d\nRemainderOf2Numbers = %d\n ", sum, minus, multiply, subtract, divide, rnums);
 }
}

Sample Output:

Input the first number: 
 6
Input the second number: 
 5
Sum = 11
Minus = 1
Multiply = 30
Subtract = 11
Divide = 1
RemainderOf2Numbers = 1

Write a program that performs arithmetic operations on three numbers instead of two.
Modify the program to take input from the user and display the results dynamically.
Perform arithmetic operations, but ensure the division operation rounds to two decimal places.
