Question

9) Create a java programming where you will enter two numbers and create only one method, which will return or display
addition, substraction, multiplication, division, average and check which number is greater than the other.
Everything in one method and call it in main method.

Answer 1

Above program is to do calculations in one function and call it in the main method

Firstly , in main method, 2 integers are entered in console

and a function calculation is called with two arguments

As the function is called, control is moved inside the function

Inside the function, addition ,subtraction, multiplication , division, average manipulations are performed and printed in the console.

After that, number is compared which one is greater using If-else blocks and printed in the console.

Below is the code in JAVA:

import java.util.*;
public class Main
{
static void calculation(int num1,int num2)
{
int sum,sub,mul,div,avg;
sum=num1+num2;
sub=num1-num2;
mul=num1*num2;
div=num1/num2;
avg=(num1+num2)/2;
System.out.println("Sum of 2 numbers: "+sum);
System.out.println("Subtraction of 2 numbers: "+sub);
System.out.println("Multiplication of 2 numbers: "+mul);
System.out.println("Division of 2 numbers: "+div);
System.out.println("Average of 2 numbers: "+avg);
if(num1>num2){
System.out.println(num1+" is greater");
}
else if(num1<num2){
System.out.println(num2+" is greater");
}
else{
System.out.println("Both numbers are equal");
}
}
   public static void main(String[] args) {
   Scanner scr=new Scanner(System.in);
       System.out.println("Enter 2 numbers");
       int num1,num2;
       num1=scr.nextInt();
       num2=scr.nextInt();
       calculation(num1,num2);
   }
}
