In this tutorial, we’ll look at how to sum the elements of an array.

Example: No user interaction

class SumOfArray{
   public static void main(String args[]){
      int[] array = {10, 20, 30, 40, 50, 10};
      int sum = 0;
      //Advanced for loop
      for( int num : array) {
          sum = sum+num;
      }
      System.out.println("Sum of array elements is:"+sum);
   }
}

Output:

Sum of array elements is:160

Example 2: User enters the array’s elements

class SumDemo{
   public static void main(String args[]){
      Scanner scanner = new Scanner(System.in);
      int[] array = new int[10];
      int sum = 0;
      System.out.println("Enter the elements:");
      for (int i=0; i<10; i++)
      {
    	  array[i] = scanner.nextInt();
      }
      for( int num : array) {
          sum = sum+num;
      }
      System.out.println("Sum of array elements is:"+sum);
   }
}

Output:

Enter the elements:
1
2
3
4
5
6
7
8
9
10
Sum of array elements is:55

In Java, encapsulation is a mechanism for combining variables (data) and methods (code) into a single unit. It is the process of concealing information details and safeguarding the object’s data and behavior. It’s one of the four key concepts in OOP. Because the encapsulating class is simple to test, it’s ideal for unit testing.In Java, encapsulation is a mechanism for combining variables (data) and methods (code) into a single unit.
