Join Peggy Fisher for an in-depth discussion in this video Understanding inheritance, part of Learning Java.
- The next topic that I'd like to talk about is inheritance.…Inheritance is when one class is created from another.…Inheritance is also a benefit…of object-oriented programming.…The new class "inherits" all the instance data…and methods from the base class,…thus reducing data redundancy.…There are numerous real life examples of this concept.…For example, we might identify a bug class,…which describes a wide range of creatures.…So ladybugs, grasshoppers, ants are all bugs.…
They all have some common characteristics,…but each one has additional features specific to them.…For example, a grasshopper can hop, a ladybug can fly.…When this type of relationship exists,…we can say that a ladybug is a bug,…a grasshopper is a bug, an ant is a bug.…This is the generic form of inheritance.…A poodle is a dog, a car is a vehicle, a circle is a shape.…The key here is the two words "is a."…This means that the specialized class…has all the characteristics of the general class,…but it also has additional characteristics…that make it unique.…
