Object Oriented Programming Methodology (CS and IT)

The Object Oriented Programming Methodology (OOPM) book provides an easy-to-follow set of code and design standards to address the basic needs of Java programmers. The book is unique, as its content touches almost every important aspect of OOP methodology and Java language, such as what is OOP, how it is different from procedural programming, fundamental concepts of OOP (including class, object, abstraction, encapsulation, inheritance, and polymorphism), features of Java language, Java installation, and arrays, string, vectors, interfaces, threads, errors, exceptions, and applet programming in Java. The book provides lots of examples in an easy-to-understand language along with exercises at the end of each chapter.

In this book, you learn about:

• • Procedural programming, top-down design and its drawbacks, OOP and its advantages, and Grady Booch methodology
  • Object, class, encapsulation or information hiding, abstraction, inheritance, polymorphism, message communication, reuse of code, coupling, cohesion, sufficiency, completeness, primitiveness, and metaclass
  • Evolution of Java, history of Java, how Java differs from other languages, features of Java language, installing and implementing

Java, Java Virtual Machine (JVM), and bytecode

• • Development of a simple Java program, identifiers, keywords, literals, constants, separators, variables, data types, operators,

expressions, and branching and looping statements

• • Class, object, method, modifier, constructor, destructor, iterator, method overloading, inheritance, method overriding, final

class, and abstract class and abstract method

• • Implementation of association, aggregation, and composition relationships Arrays, strings, and vectors
  • Interfaces, how to declare and implement interfaces in classes, variables in interfaces, how to extend an interface, and how an

interface is different from an abstract class

• • Threads, how to instantiate and start a thread, how to start and run multiple threads, different states of a thread, and how to

implement the thread synchronization mechanism and thread interaction

• • Grouping of classes for deployment and reuse, built-in packages, the java.lang package, wrapper classes, the java.util package,

and creating and using user-defined packages

• • Exception handling, try and catch blocks, finally block, handling multiple exceptions, types of exceptions, built-in exceptions,

and user-defined exceptions

• Abstract Window Toolkit (AWT), AWT frames, applets, their life cycle, how to create applets, and how to use the Graphics and Color classes
