Dynamic class invocation in Apex refers to the ability to call methods or instantiate classes at runtime using their names as strings, rather than hardcoding the specific class name or method. This provides flexibility and makes it easier to handle various objects and behaviors in a generic way. Key Concepts : Dynamic Class Instantiation : Apex allows you to instantiate classes dynamically based on their names. This is particularly useful when you have to interact with different types of classes but don't want to explicitly reference each class. Dynamic Method Invocation : You can invoke methods dynamically by using Type and Method classes, and the Reflection mechanism in Apex, enabling you to call methods based on the method name at runtime. Use of Type.forName : Apex has the Type class, which allows you to reference a class by its string name. Using Type.forName('Namespace.ClassName') , you can dynamically create objects or invoke methods. ...
