In object-oriented programming, a class is a construct that is used to create instances of itself – referred to as class instances, class objects, instance objects or simply objects. A class defines constituent members which enable its instances to have state and behavior. Data field members (member variables or instance variables) enable a class instance to maintain state. Other kinds of members, especially methods, enable the behavior of class instances. Classes define the type of their instances....

Once an object has been instantiated, we can use the dot operator to invoke its methods
Note: A method may return a value or not
String s = new String(“Hello");
int count = s.length();
System.out.println("Length of s is " + count);
Proxy class Hide implementation details of another class
Knows only public interface of class being hidden
Enables clients to use class’s services without giving access to class’s implementation. Used when class definition only uses pointer to another class Prevents need for including header file
Chapter 9 - Classes with class members. This chapter presents the following content: Class Variables, class methods, how to access class members, when to use class members, class constants, example program using class members.
Chapter 2 - Classes and methods I. In this chapter we will: describe structure of Java programs, present techniques for creating and using class instances, introduce two classes for doing output: OutputBox for text output, DrawingBox for graphical output.
Introduction to java programming: Chapter 7 - Objects and Classes's Objectives is to understand objects and classes and use classes to model objects; learn how to declare a class and how to create an object of a class; understand the roles of constructors and use constructors to create objects; use UML graphical notations to describe classes and object.
Words are fundamental units in every sentence, so we will begin by looking at these.
Consider the words in the following sentence: my brother drives a big car
We can tell almost instinctively that brother and car are the same type of word, and also that
brother and drives are different types of words. By this we mean that brother and car belong
to the same word class. Similarly, when we recognise that brother and drives are different
types, we mean that they belong to different word classes. We recognise seven MAJOR word
C# programmers: no more translating data structures from C++ or Java to
use in your programs! Mike McMillan provides a tutorial on how to use data
structures and algorithms plus the first comprehensive reference for C# implementation
of data structures and algorithms found in the .NET Framework
library, as well as those developed by the programmer.

Updating Server Data Using .NET Remoting Problem You want to update a data source using .NET remoting and use the remote application from your client application. Solution Use System.MarshalByRefObject to create a remoteable class.
SKKN: Using teaching aids in a language class help the students find it easy to perceive, understand, practise and use the item with confidence and creativity; using teaching aids is very important and necessary in new method of teaching English.
This is the first Visual Basic.NET (VB.NET) book to provide a comprehensive
discussion of the major data structures and algorithms. Here, instead of having
to translate material on C++ or Java, the professional or student VB.NET
programmer will find a tutorial on how to use data structures and algorithms
and a reference for implementation using VB.NET for data structures and
algorithms from the .NET Framework Class Library as well as those that
must be developed by the programmer.
This module continues the discussion of the class begun in Module 8. It examines a number of
class-related topics, including overloading constructors, passing objects to functions, and returning
objects. It also describes a special type of constructor, called the copy constructor, which is used when a
copy of an object is needed. Next, friend functions are described, followed by structures and unions, and
the ‘this’ keyword. The module concludes with a discussion of operator overloading, one of C++’s most
Up to this point, you have been writing programs that did not use any of C++’s object-oriented
capabilities. Thus, the programs in the preceding modules reflected structured programming, not
object-oriented programming. To write object-oriented programs, you will need to use classes. The class
is C++’s basic unit of encapsulation. Classes are used to create objects. Classes and objects are so
fundamental to C++ that much of the remainder of this book is devoted to them in one way or another. ...
