Inheritance means deriving a child class from a parent class
(i.e.existing class).
Use of inheritance iin java is we can reuse of a code.
For Ex.
class a
{
//variables.....
//methods.......
}
class b extends a
{
//variable of class a....
//methods of class a.....
//also
//variables and methods of class b
}
it means that we can inherit the class and features of
existing class in a new class.
