Default Constructor in Java It’s not required to always provide a constructor implementation in the class code. If we don’t provide a constructor, then java provides default constructor implementation for us to use. Let’s look at a simple program where default constructor is being used since...
Algorithm to Perform Constructor Chaining in Java In this possible algorithm, we are going to show you how to perform the constructor chaining process in a Java environment. By using this possible algorithm we will build some syntax, by which we will be able to describe the problem statement w...

In this blog post, we will demystify these two terms and explain the difference between them. Short answer So what’s the difference between constructor and prototype? A short answer is that the constructor is a function that is used to create an object, while the prototype is an object tha...
A friend function in C++ is defined asa function that can access private, protected and public members of a class. The friend function is declared using the friend keyword inside the body of the class. Are constructors necessary? Java doesn't require a constructorwhen we create a class. Howe...
Although it’s often mistaken for a default constructor, in Java constructors with no arguments also exist and are called “no-arg constructors.” While they share the signature with the default constructor, the body of no-arg constructors isn’t empty and they can have any code. Constructo...
