# More Midterm Review

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;
    }

## Print all elements of array

    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]);
