The last element of data2 is ghi.

Explanation:

In this code Arrays. copyOf () function copies the data of string data array into string data2 array by length-1. Here string data array has 4 element in it but according to code i. e Arrays. copyOf (data, data. length - 1); string data2 will contains only 3 element.

So the last element is "ghi", second last element is "def" and first element is "abc: in data2 array.
