Is it Possible to Call Methods of a Class Dynamically Using an Object Property?

In object-oriented programming, methods are functions defined within a class that perform actions on objects of that class. Typically, calling a method requires knowing its name. Yet, there are cases where you may want to call a method dynamically based on an object's property. This article explores the possibility of achieving this in different programming languages.

Dynamic Method Invocation in Programming Languages

1. Python

Python, a dynamically-typed language, allows dynamic method invocation. You can use the getattr() function to retrieve a method by its name, represented as a string, and then call it. Here’s an example:

2. JavaScript

JavaScript also supports dynamic method invocation. You can access an object's method using square brackets and a string for the method name. Here's an example:

3. Java

Java, a statically-typed language, does not have built-in support for dynamic method invocation using object properties. Yet, you can use reflection to achieve similar functionality. Here's an example:

Dynamically-typed languages like Python and JavaScript allow dynamic method invocation using an object property. In contrast, statically-typed languages like Java require reflection to achieve this functionality. Dynamic method invocation offers flexibility in scenarios where method names may vary, such as user input or runtime conditions.
