Object Oriented Programming using Java

We have designed this third edition of Java, Java, Java to be suitable for a typical Introduction to Computer Science (CS1) course or for a slightly more advanced Java as a Second Language course. This edition retains the “objects first” approach to programming and problem solving that was characteristic of the first two editions. Throughout the text we emphasize careful coverage of Java language features, introductory programming concepts, and object-oriented design principles.

Software engineering, unconstrained by the physics of electricity and magnetism, has long sought to build reusable, interchangeable, robust components. An important programming model that addresses the problem is called object-oriented programming (OOP). The central idea of OOP is that programs are organized as a collection of interacting objects, each with its own data space and functions. Objects can be made reusable because they encapsulate everything they need to operate, can be built with minimal or no external dependencies, and can be highly parameterized. This chapter introduces the basic concepts of OOP, including the notions of encapsulation and interface. The chapter concludes with a discussion of why OOP is important for building testbenches.

For the growth of software industry in future and the advance of software engineering, use of object-oriented programming (OOP) has increased in the software real world. Some the important features that's know is compulsory and that's features are important to study the depth knowledge of object-oriented programming in this paper, we study the concept of object-oriented programming and its features, advantages, disadvantages, and we also know the constructor and destructors

In this paper we discuss the fundamental concepts present in the object-oriented methodology. First we concentrate on the notion of an object, the key concept in this approach. A (software) object is the abstract representation of a physical or conceptual object. It consists of a name, a specified set of data-elements and methods. Data-elements can have values attached to them. Data-hiding is the feature that certain data and methods can be kept invisible (= hidden) for the outside of an object, thus facilitating its description. Only knowledge on the nature of the visible data-elements and methods is required to make proper use of the object. This is called data-abstraction. A related concept is encapsulation, a technique for achieving both data-hiding and data-abstraction. A class is a template for a number of similar objects. Classes do not prescribe values for the data-elements nor fixed implementations for their methods. A class can be seen as a set of objects that satisfy the same specification for data-elements and method-behavior. An alternative grouping of objects may take place by means of object types, as we will describe. A type is a set of objects that satisfy the same ezternai specification, i.e., specification of the visible data-elements and methods. Thus, a classification via types differs from an ordering into classes, as we shall explain. The notion of type brings along a notion of subtyping. We also discuss different forms of inheritance between classes. By means of inheritance a class can use data-and method-descriptions from another class. We describe, among other things, single inheritance, multiple inheritance and overriding. We also discuss mUltiple preferred inheritance and runtime inheritance. Finally, we show how actual programming can take place in an object oriented approach. For that we need a description of inter-object communication by means of messages. Relevant aspects are: synchronous and asynchronous message passing, scheduling and delegation. The paper concludes with an overview and a number of summarizing remarks. "'This paper originates from Marc van der Kammen's master's thesis "The logic of objects; object oriented programming in a logical perspective". It is the revised version of his chapter 0, which contains an overview of the most important basic notions concerning object-oriented programming.
