In computer science, the object lifetime (or life cycle) of an object in object-oriented programming is the time between an object's creation (also known as instantiation or construction) till the object is no longer used, and is destructed or freed.
In object-oriented programming (OOP), the meaning of creating objects is far more subtle than simple allocating of spaces for variables. First, this is because, in the OOP paradigm, the lifetime of each object tends to vary more widely than in the case in conventional programming. There are many subtle questions, including whether the object be considered alive in the process of creation, and concerning the order of calling initializing code. In some sense, the creation can happen before the beginning of the program when objects are placed in a global scope.

Famous quotes containing the words object and/or lifetime:
“Consider what effects which might conceivably have practical bearings we conceive the object of our conception to have. Then our conception of these effects is the whole of our conception of the object.”
—Charles Sanders Peirce (1839–1914)
“The modern American tourist now fills his experience with pseudo-events. He has come to expect both more strangeness and more familiarity than the world naturally offers. He has come to believe that he can have a lifetime of adventure in two weeks and all the thrills of risking his life without any real risk at all.”
—Daniel J. Boorstin (b. 1914)
