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.
An object is an instance of a class - it's a concrete 'thing' that you made using a specific class. So, 'object' and 'instance' are the same thing, but the word 'instance' indicates the relationship of an object to its class. This is easy to understand if you look at an example. For example, suppose you have a class House.
