Inheritance is a mechanism in which a new elegance is derived from an present elegance. In Java, Classes may inherit or gather the residences and Methods of different classes.
A class derived from any other class is known as a subclass, whereas the magNiFicence from which a subclass is derived is called a superclass. A subclass could have most effective one superclass, while a superclass might also have one or extra subclasses.
Inheritance is the process wherein Characteristics are inherited from ancestors. Similarly, in Java, a subclass inherits the traits (properties and methods) of its superclass (ancestor). For example, a automobile is a superclass and a vehicle is a subclass. The car (subclass) inherits all of the vehicle’s residences. The inheritance mechanism is very beneficial in Code reuse. The following are some barriers of Java class inheritance: A subclass cannot inherit Personal members of its superclass. Constructor and iNitializer Blocks can not be inherited by way of a subclass. A subclass may have simplest one superclass.
The key-word “extends” is used to derive a subclass from the superclass, as illustrated via the subsequent Syntax: elegance Name_of_subclass extends Name_of superclass //new Fields and strategies that might outline the subclass move here If you want to derive a subclass Rectangle from a superclass Shapes, you may do it as follows: magnificence Rectangle extends Shapes ….
