Let us suppose that we have the following array

int[] b = {11, 12, 15, 16, 21}

Increase all elements by 2

for (int i = 0; i < b.length; i++) {
    b[i] += 2;
}
for (int i = 0; i < b.length; i++) {
    System.out.println(b[i]);
}

Sum all the elements of an array

int sum = 0;
for (int i = 0; i < b.length; i++) {
    sum += b[i];
}

Access Last Element of Array

System.out.println(b[b.length - 1]);

Access the middle element

System.out.println(b[b.length / 2]);
