java Inheritance

Java Inheritance is a mechanism where a new class is derived from an existing class. The existing class is called the parent class or the superclass, and the new class is called the child class or the subclass. The child class inherits all the properties and methods of the parent class, and it can also define its own properties and methods.

In Java, inheritance is achieved through the use of the "extends" keyword. When a class extends another class, it inherits all the public and protected members of the parent class. The child class can then use these members as if they were its own.

Java supports single inheritance, which means that a class can only inherit from one parent class. However, Java also supports interface inheritance, where a class can implement multiple interfaces. The interfaces define a set of methods that the implementing class must implement.

Inheritance is an important concept in object-oriented programming, as it promotes code reuse and allows for the creation of complex class hierarchies.
