What are Constructors and Destructors
Constructors and destructors are special methods in object-oriented programming that are used to initialize and clean up objects, respectively.
A constructor is a method that is called when an object is created. Its primary purpose is to initialize the object's data members or properties, such as setting default values or allocating memory. Constructors can be parameterized, meaning they can take arguments that are used to initialize the object in a specific way.
In most object-oriented programming languages, the constructor method has the same name as the class and is automatically called when an object is created. However, some languages allow for multiple constructors with different signatures, which can be used to initialize the object in different ways.
A destructor is a method that is called when an object is about to be destroyed, typically when it goes out of scope or is explicitly deleted. Its primary purpose is to clean up any resources that the object has acquired during its lifetime, such as freeing memory, closing files or releasing locks.
In most object-oriented programming languages, the destructor method has the same name as the class but is preceded by a tilde (~). The destructor is automatically called when the object is destroyed, and it cannot be called explicitly.
It's important to note that not all programming languages support destructors or automatic garbage collection, so it's up to the programmer to ensure that resources are properly cleaned up when an object is no longer needed. Failure to do so can result in memory leaks or other resource leaks, which can cause problems for the application or system as a whole.
