When extending from a superclass, you may encounter code that explicitly calls super() within the constructor. While it may seem unnecessary, there are specific reasons why this practice is employed.
As Java implicitly calls super() with no arguments for all classes with a parent, an explicit call is typically not obligatory. However, the call to super() becomes essential when the parent class's constructor requires parameters and does not have a parameterless default constructor.
Additionally, explicitly calling super() with arguments provides greater control over the initialization process. Consider the following example:
<code class="java">class MyFrame extends JFrame { public MyFrame() {</code>
