What is the role of isAssignableFrom in Java?

In Java, the isAssignableFrom() method is a method of the Class class used to determine if one class can be assigned to another class. Specifically, the isAssignableFrom() method checks if a class or interface can be assigned to another class or interface. It returns true if it can, otherwise it returns false.

This method is typically used to determine the type of an object at runtime, or to determine in reflection if a class is a subclass of another or implements an interface. For example, the isAssignableFrom() method can be used to check if an object is an implementation of a certain interface, or if a class is a subclass of another class.

In general, the isAssignableFrom() method can assist us in performing type checking and type conversion operations in the program.
