Exemplification changes (#33903)

* Exemplification

Provided more comments on the coding portions to show what each line does in respect to the program. Also specified what happens when "==" is used when the "equals()" method should be employed.

 The built-in `Object` class in Java, which all other classes automatically extend, contains a number of helpful built-in methods. One such method is `equals()`, which takes another object as its argument and returns whether the two objects should be considered "equal" according to the relevant logic for that class.
 
-The 'String' class is one of the most common examples of a class that overrides the `equals()` method. When comparing two 'String's for equality, you need to use the `equals()` method, as `==` won't work as you expect.

When comparing two 'String's for equality, you need to use the 'equals()' method, as '==' won't work as you expect. Instead of returning 'true' when comparing objects, the '==' operator will continuously return 'false' unless the objects being compared are the *same object*.

 When you create a new class in Java, you will often want to override the `equals()` method in order to provide a more meaningful way to compare two objects of the same class. How this method is implemented is completely up to the developer's judgement.
