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, while object-oriented programming focus on both of them

Object-Oriented Programming (OOP) Inheritance - form of software reusability New classes created from existing ones Absorb attributes and behaviors, and add in their own Override methods - redefine inherited methods Subclass inherits from superclass Direct superclass - subclass explicitly inherits Indirect superclass - subclass inherits from two or more levels up the class hierarchy Polymorphism Write programs in a general fashion to handle a wide variety of classes Abstraction - seeing the big picture...

A technique for developing a program in which the solution is expressed in terms of objects -- self- contained entities composed of data and operations on that data. Programmer thinks about and defines the attributes and behavior of objects. Often the objects are modeled after real-world entities. Very different approach than function-based programming (like C).

The Java standard APIs are shown in HTML output at http://java.sun.com/j2se/1.4.2/docs/api/index.html. It’s generated from the documentation comments (doc comments). Documentation comments are special comments in the source code that are delimited by the /** ... */ delimiters.

A collection is a data structure – actually, an object – to hold other objects, which let you store and organize objects in useful ways for efficient access Check out the java.util package! Lots of interfaces and classes providing a general collection framework. Programmers may also provide implementations specific to their own requirements

Creative writing is any writing that goes outside the bounds of normal professional, journalistic, academic, or technical forms of literature, typically identified by an emphasis on narrative craft, character development, and the use of literary tropes. Due to the looseness of the definition, it is possible for writing such as feature stories to be considered creative writing, even though they fall under journalism, because the content of features is specifically focused on narrative and character development.

Welcome to the module, Internationalization. This module provides a brief introduction of developing applications for the global market. The module covers the process of internationalization and localization to create applications, which are neutral in terms of countries, languages and regions. Internationalized applications require meticulous planning, failing which re-engineering of the application can be costly. In this module, you will learn about:

A java application can run inside a JVM and can only invoke the methods of the classes available inside this JVM • Distributed computing or processing resolves around clientserver technology where several client programs communicate with one or more server applications.An RMI application has to expose methods, which remote clients can invoke. • These methods which are meant to be remote, should be defined in an interface which extends the java.rmi.Remote interface

Mechanism to create new classes using existing classes The existing class is called the parent class, or superclass, or base class The derived class is called the child class or subclass As the name implies, the child inherits characteristics of the parent That is, the child class inherits the methods and data defined by the parent class. Once a behavior (method) is defined in a super class, that behavior is automatically inherited by all subclasses

Real world concepts can be modeled in a computer program The program is made of objects with certain properties and operations that the objects can perform It is not important how an object is implemented, but what it does Every object is responsible for carrying out a set of related tasks. A class can contain data declarations and method declarations
