Question

object oriented programming Jaya

Write a complete program using function/Method named Average to calculate of four numbers entered by user (treat the four variables as local in main). Read the four numbers in main function and send them as parameter to the function Average. (Marks are allocated to function prototype, function call and function definition).

Answer 1

//You should save the below code as Average4.java
import java.util.Scanner;
public class Average4 {
    public static double average(int n1, int n2, int n3, int n4){
        // Calculating sum
        int sum = n1+n2+n3+n4;

        // Calculating average and return
        return sum/4.0;
    }
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);

        // Prompt for three numbers
        System.out.println("Enter four numbers:");

        // Reading three numbers
        int n1 = scan.nextInt();
        int n2 = scan.nextInt();
        int n3 = scan.nextInt();
        int n4 = scan.nextInt();

        double avg = average(n1,n2,n3,n4);

        // Printing average of three numbers
        System.out.println("average is: "+avg);

    }
}

Output

Enter four numbers: 43 65 87 26 average is: 55.25
