Topic: Subclass (computer science)


  
  Subclass (computer science) Summary
In object-oriented programming, a subclass is a class that inherits some properties from its superclass.
In this way, a subclass is a more specific version of its superclass; that is, the facts about the cat state what is generally true for all cats, even if some kinds of cats happen to have no tail.
Subclasses and superclasses are often referred to as derived and base classes, respectively, terms coined by [[C++]] creator Bjarne Stroustrup, who found these terms more intuitive than the traditional nomenclature.

 Object (computer science) Summary
In strictly mathematical branches of computer science the term object is used in a purely mathematical sense to refer to any "thing".
Note that although a block of computer memory can appear contiguous on one level of abstraction and incontiguous on another, the important thing is that it appears contiguous to the program that treats it as an object.
Objects exist only within contexts that are aware of them; a piece of computer memory only holds an object if a program treats it as such (for example by reserving it for exclusive use by specific procedures and/or associating a data type with it).

The 'computable numbers' paper is now recognised as one of the most important milestones in the history of computer science.
The Japanese plans for fifth-generation computers require massive funding in AI research and development (see Simons, 1983), and increasing commercial emphasis is being given to the development of particular expert systems for specific purposes (medical diagnosis, crop disease diagnosis, geological prospecting, electronic circuit analysis, chemical synthesis, etc).
Computer systems based on AI techniques are now available as aids for a wide range of professional workers: mathematicians, engineers, doctors, teachers, chemists, geologists, biologists, lawyers, office and factory managers, etc. There is a growing recognition that AI facilities will become essential to commercial success.

The considerable theoretical power of a quantum computer derives from its ability to process *coherent quantum states (i.e., quantum states obeying the principle of superposition), but the coherence of such quantum states is very easily damaged by uncontrolled interactions with the environment (decoherence).
A quantum computer executes a series of elementary quantum gates, each of which is a *unitary transformation that acts on a single qubit or pair of qubits.
In contrast, in a quantum computer, the qubit (the fundamental unit of information) might be represented by an atom in one of two different states, 0 or 1, but unlike classical bits, qubits can exist simultaneously as 0 or 1, with the probability for each state given by a numerical coefficient.

 SUPER-RECURSIVE ALGORITHMS AS A TOOL FOR HIGH PERFORMANCE COMPUTING
They introduced the concept of computability in a limit (or, as it is more correctly to call it, inductive computability) and were aimed at a description of the computations in the limit as well as other algorithmic processes (e.g., learning a language or development of mathematics).
The concept of the inductive computability suggested in (Gold 1965; Putnam 1965) as well as its development in (Burgin 1983) are rooted in the constructions of non-standard analysis (Robinson 1966) and inductive definition of sets (Spector 1959).
At the same time, inductive computability is a partial case of the topological computability defined in (Burgin 1983) being the case when the output domain has the discrete topology.

 Object Oriented Programming Lab Notes
Connecting this with the subclass students define, we want students to personally see that instances of the subclass handle messages whose methods are inherited as well as messages whose methods the students defined in the subclass.
While this problem may be one of the hardest parts of the lab for many students, we feel that it is a good application of the subclass from Part 1, a good exercise in object oriented programming, and the practice in problem solving is a desirable side benefit.
Because this lab explicitly uses preconditions in the specifications for subclass methods, doing the lab will expose such misconceptions, and give instructors a chance to correct them, either in conversation with students during the lab, or while grading it.

That reminds us the time (before the 20s of last century) when science was not able to interpret the properties of electrons, atoms, and molecules.
A computer is driven by a program, its content, however computer 'science' just makes the very first steps in this direction; for now, it is very much computer/programming technology and tools which may interpret the content and use it to drive the actions

 Superclass (computer science) - Wikipedia, the free encyclopedia
In computer science, a superclass is a class from which other classes are derived.
The classes that are derived from a superclass are known as child classes, derived classes, or subclasses.
The superclass mechanism is extensively used in object oriented programming due to the reusability that can be achieved: common features are encapsulated in modular objects.
