Also, an independent contractor is generally one who has the opportunity to make a profit, or the risk of taking an out-of-pocket loss, while an employee generally does not have that opportunity nor does he take that risk.
Inheritance is the process wherein characteristics are inherited from ancestors. Similarly, in Java, a subclass inherits the characteristics (properties and methods) of its superclass (ancestor). For example, a vehicle is a superclass and a car is a subclass. The car (subclass) inherits all of the vehicleâs properties.
The idea behind inheritance is that you can create new classes that are built on existing classes. When you inherit from an existing class, you reuse (or inherit) its methods and fields and you add new methods and fields to adapt your new class to new situations. This technique is essential in Java programming.
