I want perform an operation on some elements of an array, but I don't know how I can exclude some and include some.

Question

For example, I have an array declared as
int a[]=new int[20]
And I have saved something in the 20 array elements. If I want to add something or check something from some of the elements without doing it on others, how can I go about it?

Answer 1

You can access that particular element using it's index position to alter or to check for the value.
