Exploring the Purpose of super() Invocation in Constructors

When working with class hierarchies, inheritance plays a crucial role in reusing code and extending functionalities. However, in cases where a subclass extends a superclass, you may wonder why it's necessary to invoke super() within the constructor.

Understanding the Implicit super()

In Java, every user-defined class implicitly inherits from the Object class. This means that all classes have a hidden super() call with no arguments. Typically, this implicit call suffices for accessing methods and properties of the superclass.

Explicit super() with Arguments

However, in certain scenarios, an explicit super() invocation becomes necessary. If the superclass constructor requires parameters, you must specify them using super(). For example, if the JFrame constructor takes a title parameter, you can set it explicitly:

<code class="java">class MyFrame extends JFrame {
    public MyFrame() {</code>
