Computing the total hours worked
<p>I can't figure out at the moment how am I going to calculate the total hours worked of an employee. Example:</p>

<pre><code>Time-in: 07:00
Time-out: 05:00
</code></pre>

<p>I have two JTextField, that's where the user will input. How am I going to do it when he clicks my JButton Calculate Hours? Sorry guys, I know this is pretty easy but I am completely a novice, please help!</p>
