+# More Midterm Review
+
+Let us suppose that we have the following array
+
+```java
+int[] b = {11, 12, 15, 16, 21}
+```
+
+## Increase all elements by 2
+
+```java
+for (int i = 0; i < b.length; i++) {
+    b[i] += 2;
+}
+```
+
+## Print all elements of array
+
+```java
+for (int i = 0; i < b.length; i++) {
+    System.out.println(b[i]);
+}
+```
+
+## Sum all the elements of an array
+
+```java
+int sum = 0;
+for (int i = 0; i < b.length; i++) {
+    sum += b[i];
+}
+```
+
+## Access Last Element of Array
+
+```java
+System.out.println(b[b.length - 1]);
+```
+
+## Access the middle element
+
+```java
+System.out.println(b[b.length / 2]);
+```
