Integer getSum(Integer[] intArray)

• Description
  • Given an Integer array, intArray, return the sum of all values in the array.

Example

• Sample Script

  // : Given
  Integer[] input = { 1, 2, 3, 4, 5};
  
  // : When
  Integer outcome = IntegerArrayUtils.getSum(input);
  
  // : Then
  System.out.println(outcome);
  

• Sample Output

  15

Example

• Sample Script

  // : Given
  Integer[] input = { 1, 2, 3, 4, 5};
  
  // : When
  Integer outcome = IntegerArrayUtils.getProduct(input);
  
  // : Then
  System.out.println(outcome);
  

• Sample Output

  120
