average of n numbers in java code example

Example 1: Java program to find average of n numbers

// 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();
   }
}

Example 2: java program to calculate average of n numbers

int a, b, c, d;
		a = 2;
		b = 3;
		c = 5;
		d = 10;
		System.out.println("Average of n nubers is: " + (a + b + c + d) / 4);
		// OR
		Scanner scanner = new Scanner(System.in);
		System.out.println("Enter 1st number: ");
		int firstNumber = scanner.nextInt();
		System.out.println("Enter 2nd number: ");
		int secondNumber = scanner.nextInt();
		System.out.println("Enter 3rd number: ");
		int thirdNumber = scanner.nextInt();
		System.out.println("Enter 4th number: ");
		int fourthNumber = scanner.nextInt();
		System.out.println("Enter 5th number: ");
		int fifthNumber = scanner.nextInt();
		System.out.println("Enter 6th number: ");
		int sixthNumber = scanner.nextInt();
		System.out.println("Enter Nth number: ");
		int nthNumber = scanner.nextInt();
		scanner.close();
		System.out.println("Average of abouve input numbers is: "
				+ (firstNumber + secondNumber + thirdNumber + fourthNumber + fifthNumber + sixthNumber + nthNumber)
						/ 7.0);
