Object Lifecycle
In object-oriented programming (OOP), the object lifetime (or life cycle) of an object (computing), object is the time between an object's Instance (computer science)#Object-oriented_programming, creation and its destruction. Rules for object lifetime vary significantly between Programming language, languages, in some cases between Programming language implementation, implementations of a given language, and lifetime of a particular object may vary from one Runtime (program lifecycle phase), run of the program to another. In some cases, object lifetime coincides with variable lifetime of a Variable (computer science), variable with that object as value (both for static variables and automatic variables), but in general, object lifetime is not tied to the lifetime of any one variable. In many cases – and by default in many object-oriented languages, particularly those that use Garbage collection (computer science), garbage collection (GC) – objects are allocated on the Heap (pr ...

Object-oriented Programming
Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data and code. The data is in the form of fields (often known as attributes or ''properties''), and the code is in the form of procedures (often known as ''methods''). A common feature of objects is that procedures (or methods) are attached to them and can access and modify the object's data fields. In this brand of OOP, there is usually a special name such as or used to refer to the current object. In OOP, computer programs are designed by making them out of objects that interact with one another. OOP languages are diverse, but the most popular ones are class-based, meaning that objects are instances of classes, which also determine their types. Many of the most widely used programming languages (such as C++, Java, Python, etc.) are multi-paradigm and they support object-oriented programming to a greater or lesser degree, typically in combination with imper ...
