Polymorphism
Definition:
In computer science, polymorphism refers to the ability of an object to take on many forms. It is a fundamental concept in object-oriented programming, where a single interface can be implemented by multiple classes. Polymorphism allows for code reusability, flexibility, and efficient maintenance.
Senses and Usages:
-
Sense 1: Polymorphism in Object-Oriented Programming
In object-oriented programming, polymorphism allows objects of different classes to be treated as objects of a common superclass or interface. This enables the use of generalization and inheritance, offering flexibility in designing and implementing software systems.
For example, consider a program that models different shapes: circle, square, and triangle. Each shape inherits from a common interface called "Shape." With polymorphism, the program can use a single method, such as "calculateArea()", which will behave differently depending on the actual type of shape created.
Sample Sentence: Polymorphism in Java allows programmers to write generic algorithms that can operate on different types of objects without needing to know their specific classes.
-
Sense 2: Genetic Polymorphism
In biology, polymorphism refers to the occurrence of two or more different forms within a population of a species. It can involve variations in physical traits, such as color or size, or genetic variations.
For example, the coloration differences seen in butterflies or the presence of different blood types in humans are examples of genetic polymorphism.
Sample Sentence: The genetic polymorphism observed in a population of birds allowed some individuals to adapt better to their changing environment.
