Constructor, as the name suggests is used to allocate memory (if required) and construct the objects of a class while destructor is used to do the required clean-up when a class object is destroyed. In this article, we will study the concept of constructors and destructors through working e...
Static constructors find its major use in log programs where it is used to write the parameter entries initialized during each instance. Static constructors are the ideal positions to create database connections as they are loaded first and remain static throughout. In C# programming language the ...
While calling the constructor, it might be needed to pass the value from where it has been called or it may not be required. Above are the syntax of both the ways to call the constructor. While bringing the constructor in use, one has to make sure that the syntax has to be followed ...

When used in overloading, such functions are called factory methods. We can use them to implement the concept of constructor overloading in Python. Example: classdelftstack(object):def__init__(self,a):self.ans="a"@classmethoddeffirst(cls):return"first"@classmethoddefsecond(cls):return"secon...
