| For example, |
| suppose that we wanted to create a subclass named
SubClass of another class named SuperClass. We would write: |
| |
class SubClass extends SuperClass
{
. . .
} |
| |
| |
| This declares that SubClass is the subclass of the Superclass class.
It also implicitly declares that SuperClass is the superclass of SubClass.
A subclass also inherits variables and methods from its superclass's
superclass, and so on up the inheritance tree.
|
| |
| A Java class can have only one direct superclass. |
| Java does not support multiple inheritance. |
| |
| Creating a subclass can be as simple as including the
extends clause in your class declaration. |
