  • A class can contain private as well as public members. By default, all items defined in a class are private. This means that they can be accessed only by other members of their class, and not by any other part of your program. This is one way encapsulation is achieved—you can tightly control access to certain items of data by keeping them private.

  • 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. ...

  • JDBC has simplified database access in Java applications, but a few nagging wrinkles remain—namely, persisting Java objects to relational databases. With this book, you’ll learn how the Spring Framework makes that job incredibly easy with dependency injection, template classes, and object-relational-mapping (ORM). Through sample code, you’ll discover how Spring streamlines the use of JDBC and ORM tools such as Hibernate, the Java Persistence API (JPA), and Java Data Objects (JDO).

  • Once an object has been instantiated, we can use the dot operator to invoke its methods title.length(); Note: A method may return a value or not Example: String s = new String(“Hello"); int count = s.length(); System.out.println("Length of s is " + count);

  • 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.[1] 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.[2]...

  • Outline: Classes, Working with objects, Attributes, methods, and access control, Constructors. Readings: Java how to program, chapter 3, 8. A Java program is a collection of objects. Each class is specified in one source file (file name is the same with class name), Every line of code you write in Java must be inside a class (not counting import directives), Increase modularity, Easier to modified code, shorter compile time.

  • Beginning Object-Oriented Programming with VB 2005 is a comprehensive resource of correct coding procedures. Author Daniel Clark takes you through all the stages of a programming project, including analysis, modeling, and development, all using object-oriented programming techniques and Visual Basic .NET. Clark explores the structure of classes and their hierarchies, as well as inheritance and interfaces. He also introduces the .NET Framework and the Visual Studio integrated development environment, or IDE. A real-world case study walks you through the design of a solution.

  • Describe Single Inheritance Describe Base class and Derived class Access Base class members and use pointers in classes Describe types of inheritance Describe Constructors and Destructors under inheritance Describe how to call Member Functions of the Base Class and Derived Class Describe Container Classes To maintain and reuse class objects easily, we need to be able to relate classes of similar nature to another. Single inheritance is the process of creating new classes from an existing base class.

  • Procedural vs. Object-Oriented Programming The unit in procedural programming is function, and unit in object-oriented programming is class Procedural programming concentrates on creating functions, while object-oriented programming starts from isolating the classes, and then look for the methods inside them. Procedural programming separates the data of the program from the operations that manipulate the data,
