The default constructor initializes any uninitialized instance variables with default values. … Example 5: Default Constructor.

In Java, two or more methods may have the same name if they differ in parameters (different number of parameters, different types of parameters, or both). These methods are called overloaded methods and this feature is called method overloading. For example: void func() { . .. }
Read moreWhat is the use of constructor overloading?
If we want to have different ways of initializing an object using different number of parameters , then we must do constructor overloading as we do method overloading when we want different definitions of a method based on different parameters.28 Haz 2021
Read moreHow is the parameterized constructor called?
Parameterized constructors When an object is declared in a parameterized constructor, the initial values have to be passed as arguments to the constructor function. The normal way of object declaration may not work. The constructors can be called explicitly or implicitly .
Read moreWhat is the advantage of constructor overloading in C++?
Answer: Benefits of constructor overloading in C++ is that, it gives the flexibility of creating multiple type of objects of a class by having more number of constructors in a class , called constructor overloading. In fact, it is similar to C++ function overloading that is also know as compile time polymorphism.
Read moreIs constructor overloading possible if yes then explain and if no then why?
Answer: No, we cannot overload a destructor of a class in C++ programming . Only one empty destructor per class should be there. It must have a void parameter list. Destructor in C++ neither takes any parameters nor does it return anything.
Read moreWhat is constructor overloading Why do we use it?
Why do we use constructor overloading? Explanation: The constructors are overloaded to initialize the objects of a class in different ways . This allows us to initialize the object with either default values or used given values.
