Inheritance is one of the feature of Object-Oriented Programming (OOPs). Inheritance allows a class to use the properties and methods of another class. In other words, the derived class inherits the states and behaviors from the base class. The derived class is also called subclass and the base class is also known as super-class. The derived class can add its own additional variables and methods. These additional variable and methods differentiates the derived class from the base class.
1. Inheritance is a compile-time mechanism. A super-class can have any number of subclasses. But a subclass can have only one superclass. This is because Java does not support multiple inheritance.
2. The superclass and subclass have “is-a” relationship between them.
Single Inheritance
• When a class inherits from only one class, it is called single inheritance.
• Interfaces provide the benefits of multiple inheritance without drawbacks.
• Syntax of a Java class is as follows:
A subclass can modify behavior inherited from a parent class.
• A subclass can create a method with different functionality than the parent’s method but with the same:
• Name
• Return type
• Argument list
