Consider the following code snippet in Java 6 or later: String[] data = { "abc", "def", "ghi", "jkl" }; String[] data2 = Arrays.copyOf(data, data.length - 1); What does the last element of data2 contain?

Respuesta :

Answer:

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.
