final only can make a reference unchangeable.If I declare a array like this:

private final int[] a = {1,2,3,4,5};

I can change the value of a[i] just by using

a[i]++;

How can I do to make sure the element of array will not be changed during the program running?

You cannot make an array of `int`s immutable, what you *can* do is pass a copy of your array instead of the original one. – Nir Alfasi Jul 15 '15 at 05:19
