<h2>Arrays (Cont.)</h2>
<h3>Another way of Array Initialization</h3>
<pre><code class="language-java">String[] names = {"Jennifer", "Noodle", "Fluffy", "Rosie", "Cinnamon", "Brianne", "Oliver"}</code></pre>
<p>Everything between the <code>{}</code> is the initial values in the names array in the order that it is written.</p>
<p>Recall that arrays are of a fixed size. The <code>names</code> array above has 7 elements.</p>
<h3>What can I do if I want to add something to the names array?</h3>
<p>Do the following steps:</p>
<ol>
<li>Create an empty array with the same size as the array</li>
<li>Take all the contents in the array and store it in a temporary array</li>
<li>Set names equal to another array of a bigger size</li>
<li>Take all the contents in temp and store it back to the array of choice</li>
<li>Add an element to the array by index</li>
</ol>
<pre><code class="language-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!";</code></pre>
