This chapter expands on the discussion of classes and how to create programs with them.

Java:

• Inheritance - one of the most important aspects of OOP is the ability to create a new class that extends, i.e. inherits, the capabilities of another class.
  • Demo 1: Inheritance
    
• Method Overriding - the subclass that extends a class, called the base class, can contain new versions of methods in the base class. This  technique provides for so-called polymorphism.
  • Demo 2: Two overriding demonstration programs
    
• this and super references allow access to overloaded and overriden methods.
• More about Constructors
  • Demo 3: Constructors
• Abstraction provides for great flexibility and conceptual clarity when designing a class framework.
• Interface - essentially a class with only abstract methods. They are used in Java in place of multiple inheritance and for callbacks.
  • Demo 4: Interface
    
• Casting class references
• More about arrays - creating arrays of objects, multi-dimensional arrays, and array as an object.
• Object class
• Summary of classes and objects

Supplements:

• Overriding and Overloading - using a visual guide to methods in a class heirarchy.
• Annotation in J2SE5.0
• Security in Java - a brief overview. Then more about:
  • ClassLoaders
  • Class Verification
  • SecurityManagers

Tech:

• Improved complex number class
• Enhanced histogram class.
• Random number generation - the tools available in the core Java to create random values.
• Vector and matrix representations and operations.

Physics:

• Solving ODE with
  • Second-order Runge-Kutta
  • Fourth-order Runge-Kutta
• Boundary-value Problems
  • Shooting method to solve them.
