Question

draw a program to find average of three numbers​

Answer 1

-->Using Variable Initialization:

public class Average

{   

public static void main(double a, double b, double c)

{  

double sum = a + b + c;   

 double avg = sum/3;         

System.out.println ("Average: " + avg );  

 }

}

-->Using Scanner:

import java.util.Scanner;

public class average

{

public static void main(String[] args)

{

Scanner scan = new Scanner(System.in); System.out.print("Enter the first number: ");

double num1 = scan.nextDouble();

System.out.print("Enter the second number: ");

double num2 = scan.nextDouble();

System.out.print("Enter the third number: ");

double num3 = scan.nextDouble();

scan.close();

System.out.print("The average of entered numbers is:" + avr(num1, num2, num3));

}

public static double avr(double a, double b, double c)

{

return (a + b + c) / 3;

}

}

Answer 2

This program is in Java.  

import java.util.*;

public class AverageCalculator {

   public static void main (String [] args) {

       //Taking input from the user

       Scanner sc = new Scanner(System.in);

       System.out.print("Enter the first number: ");

       double num1 = sc.nextDouble();

       System.out.print("Enter the second number: ");

       double num2 = sc.nextDouble();

       System.out.print("Enter the third number: ");

       double num3 = sc.nextDouble();

       //Main part comes here

       double Average = (num1 + num2 + num3) / 3;

       System.out.println("The average of the given numbers is " + Average);

   }

}

Output:

Enter the first number: 30

Enter the second number: 31

Enter the third number: 28

The average of the given numbers is 29.666666666666668
