In the Parsons problem exam question, the first example shown, there are 6 pairs of statements, one mark is deducted for each incorrectly chosen line from the pairs, two marks are deducted if more than 2 lines are out of place, and one mark is deducted if up to two things are out of place.
Classes may inherit from other classes, so they are arranged in a hierarchy that represents "is-a-type-of" relationships. For example, class Employee might inherit from class Person. All the data and methods available to the parent class also appear in the child class with the same names.
Composition over inheritance (or composite reuse principle) in object-oriented programming (OOP) is the principle that classes should favor polymorphic behavior and code reuse by their composition (by containing instances of other classes that implement the desired functionality) over inheritance from a base or parent class.

[26] [27] In C++, an abstract class is a class having at least one abstract method given by the appropriate syntax in that language (a pure virtual function in C++ parlance). [25] A class consisting of only pure virtual methods is called a pure abstract base class (or pure ABC) in C++ and is also known as an interface by users of the language. [13]
There are three kinds of message sends, unary messages which have a single keyword, such as class and size, binary messages which for example are used for arithmetic, such as a < b, a ~= b, and keyword messages where a keyword followed by a colon precedes each argument in the message, so that a between: b and: c sends the #between:and: message ...
A class diagram exemplifying the singleton pattern.. In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance.
The class keyword can also be used in the form Class.class to get a Class object without needing an instance of that class. For example, String.class can be used instead of doing new String().getClass(). continue Used to resume program execution at the end of the current loop body.
