how to get average of 3 numbers in java code example
Example 1: Java program to calculate average of 3 numbers
import java.util.Scanner;
public class AverageNumberDemo
{
public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
System.out.print("Please enter first number: ");
double number1 = sc.nextDouble();
System.out.print("Please enter second number: ");
double number2 = sc.nextDouble();
System.out.print("Please enter third number: ");
double number3 = sc.nextDouble();
System.out.print("The average of 3 numbers is: " + calculateAverage(number1, number2, number3));
sc.close();
}
public static double calculateAverage(double num1, double num2, double num3)
{
return (num1 + num2 + num3) / 3;
}
}
Example 2: Java program to find average of n numbers
import java.util.Scanner;
public class FindAverageOfNNumbers
{
public static void main(String[] args)
{
int num, count = 1;
float a, average, total = 0;
Scanner sc = new Scanner(System.in);
System.out.println("Please enter n numbers: ");
num = sc.nextInt();
while(count <= num)
{
System.out.println(count + " number: ");
a = sc.nextInt();
total += a;
++count;
}
average = total / num;
System.out.println("Average is: " + average);
sc.close();
}
}
