In the same way, sound spreads out in waves from the place where it is first made. The sound waves, like the ripples in the lake, become weaker the farther they travel. The energy of the waves becomes more spread out. Scientists use units called decibels to measure the intensity of sound.
Polymorphism in C#: Introduction and Types. The word polymorphism can be broken down into two different words, âpolyâ meaning many and âmorphâ meaning forms, and hence the meaning âhaving many formsâ. In C#, or for that matter in any object oriented programming language, polymorphism is used to imply one name with multiple functionality. In polymorphism we declare methods with the same name and different parameters in same class or methods with the same name and same parameters in different classes. Polymorphism has the ability to provide different implementation of methods that are implemented with the same name.
The dictionary definition of polymorphism refers to a principle in biology in which an organism or species can have many different forms or stages. This principle can also be applied to object-oriented programming and languages like the Java language. Subclasses of a class can define their own unique behaviors and yet share some of the same functionality of the parent class. Polymorphism can be demonstrated with a minor modification to the Bicycle class. For example, a printDescription method could be added to the class that displays all the data currently stored in an instance.
