Introduction:

In the realm of software development, adaptability and flexibility are essential qualities. As the demand for more dynamic and extensible applications grows, the ability to load classes dynamically at runtime becomes increasingly valuable. Java, being a highly versatile language, offers a powerful mechanism known as “dynamic class loading” to achieve this level of runtime flexibility. In this article, we will delve into the world of Java dynamic class loading, exploring its concepts, practical applications, and the benefits it brings to software development.

Understanding Dynamic Class Loading:

Dynamic class loading in Java refers to the process of loading and using classes at runtime, instead of loading them during the static compilation phase. By dynamically loading classes, Java programs gain the ability to load and execute code on-demand, thereby enabling the creation of more flexible and extensible applications.

Java provides a rich set of APIs and mechanisms to dynamically load classes, such as the Class.forName() method, ClassLoader instances, and reflection. Let’s explore these concepts further with some code examples.

Using Class.forName():

The Class.forName() method allows us to dynamically load a class by providing its fully qualified name as a string. It returns a Class object representing the loaded class, which can be used to…
