+## Arrays (Cont.)
+
+### Another way of Array Initialization
+
+```java
+String[] names = {"Jennifer", "Noodle", "Fluffy", "Rosie", "Cinnamon", "Brianne", "Oliver"}
+```
+
+Everything between the `{}` is the initial values in the names array in the order that it is written.
+
+Recall that arrays are of a fixed size. The `names` array above has 7 elements.
+
+### What can I do if I want to add something to the names array?
+
+Do the following steps:
+
+1. Create an empty array with the same size as the array
+2. Take all the contents in the array and store it in a temporary array
+3. Set names equal to another array of a bigger size
+4. Take all the contents in temp and store it back to the array of choice
+5. Add an element to the array by index
+
+```java
+// (1)
+String[] temp = new String[7];
+// (2)
+temp.clone(names);
+// (3)
+names = new String[20]; // Now it can hold up to 20 names
+// (4)
+names.clone(temp);
+// (5)
+names[7] = "New name!";
+```
