A program is required to three (3) numbers. calculate and print their total
podryga [215]

A program that is required to three (3) numbers. calculate and print their total is given below:

<h3>The Program</h3>

import java.util.Scanner;

public class SumAndAverage {

public static void main(String[ ] args) {

System.out.println("Enter three numbers - ");

// Accepting and finding sum of numbers.

int sum = 0;

Scanner sc = new Scanner(System.in);

for (int i = 0; i < 3; i++)

sum += sc.nextInt( );

// Printing sum and average.

System.out.println("Sum - " + sum);

System.out.println("Average - " + (sum / 3f));

}

}

The output would request three different numbers, then add them up, and display the output of the sum and then display or print their total
