Add example demonstrating default Object toString() behavior in Java

Created a `student` class with fields `studentID` and `name`, along with a constructor to initialize them.
In the `toStringMethod` class, instantiated two `student` objects and printed them using `toString()`.

Logic: Since the `toString()` method is not overridden, the output shows the default implementation from `Object` class — which prints the class name followed by the object's hash code in hexadecimal. Comments in the code explain how `Object.toString()` works internally and what it returns if not overridden.

Prepared the code to allow comparison by optionally uncommenting the custom `toString()` method.
