Question

What is the difference between an internal and an external method call? In what situation would only internal calls be needed?

Answer 1

Step-by-step explanation:

The difference between internal method call and external method call are as follows:-

Internal Method calls means when the function is called using the object of the class in the same class which is defined but where as in case of external method , it calls the function are called from other class by creating the object the respected class in other class and the function is called .

Suppose there is only one class and that class is only having all the methods and function declaration and there is no other class described . So in this case we will use the internal Method calls only .
