Java – Sum of Array elements

Java – Program to find the sum of array elements

class Code {             public static void main(String[] args)             {                         int[] arr = {6, 3, 9, 1, 2, 8, 4, 5};                         int sum=0;                         for (int i=0 ; i<arr.length ; i++)                         {                                     sum = sum + arr[i];                         }                         System.out.println(“Sum of elements : ” + sum);             } }

Java – Program to find sum of array elements using for each loop

class Code {             public static void main(String[] args)             {                         int[] arr = {6, 3, 9, 1, 2, 8, 4, 5};                         int sum=0;                         for (int x : arr)                         {                                     sum = sum + x;                         }                         System.out.println(“Sum of elements : ” + sum);             } }

Java – Program to find the average of array elements

class Code {             public static void main(String[] args)             {                         int[] arr = {6, 3, 9, 1, 2, 8, 4, 5};                         double sum=0;                         for (int x : arr)                         {                                     sum = sum + x;                         }                         double avg = sum/arr.length;                         System.out.println(“Average of array elements : ” + avg);             } }
