We use constructors to initialize the object with the default or initial state . The default values for primitives may not be what are you looking for. Another reason to use constructor is that it informs about dependencies.
Read moreWhy is it important to have constructors in a class?
Importance of constructors Constructors are used to initialize the objects of the class with initial values . Constructors are invoked automatically when the objects are created. Constructors can have default parameters. If constructor is not declared for a class , the C++ compiler generates a default constructor.
Read moreWhat is constructor give an example?
Constructors have the same name as the class or struct, and they usually initialize the data members of the new object. In the following example, a class named Taxi is defined by using a simple constructor . This class is then instantiated with the new operator.
Read moreWhat is overloading explain with example?
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 an overloading constructor?
The technique of having two (or more) constructors in a class is known as constructor overloading. A class can have multiple constructors that differ in the number and/or type of their parameters.
Read moreWhat is constructor overloading with example?
Constructor overloading is a concept of having more than one constructor with different parameters list, in such a way so that each constructor performs a different task . For e.g. Vector class has 4 types of constructors.
Read moreIs overloading possible in constructor?
Constructors can be overloaded in a similar way as function overloading . Overloaded constructors have the same name (name of the class) but the different number of arguments. Depending upon the number and type of arguments passed, the corresponding constructor is called.
