A constructor is a special type of method used in object-oriented programming languages to initialize objects. The constructor is called automatically every time when an object is created, allowing the object to set initial values for its attributes or perform other setup tasks. In class-based, object-oriented programming, a constructor (abbreviation: ctor) is a special type of function called to create an object. It prepares the new object for use, often accepting arguments that the constructor uses to set required member variables. Java constructors are special types of methods that are used to initialize an object when it is created. It has the same name as its class and is syntactically similar to a method. However, constructors have no explicit return type. We must need a matching constructor. But what the heck is that? Constructors A constructor is a special member function that is automatically called after a non-aggregate class type object is created. When a non-aggregate class type object is defined, the compiler looks to see if it can find an accessible constructor that is a match for the initialization values provided by the caller (if any). If an accessible matching constructor is found, memory for the object is allocated, and then the ...
