Question

Creating sub-array

Asked by: ubuntuguy

Is it possible to create a sub-array from an array directly without having to copy the elements?

Let's say that I have an array of length 1000, and I want to create an array from index 0 to index 400.

Without having to copy each element into a new array, can I do something like int [] newArray = oldArray(startIndex, endIndex)?
