Module 1 (Detailed)

Detailed explanations of approaches to software design, object modeling with UML (and specific diagram types).
In-depth introduction to the Java programming environment, runtime environment, and development platforms.
Key concepts about the Java Virtual Machine, compiler, bytecode, applets, and basic Java structure, comments, garbage collection, and lexical issues.

Software Design

Software design is the process to transform user requirements into a form that helps programmers implement the software.
It involves specifying the software artifact with primitive components and constraints to reach stated goals.
There are two main approaches: top-down and bottom-up.
Bottom-up entails assembling utility routines early. In contrast top-down approaches entail breaking bigger problems into sub-tasks in a hierarchy.

Function Oriented Design (FOD)

An approach where system is divided into functional units responsible for clearly defined tasks.
System state is centralized among functionalities.
Top-down methods are often employed to refine functions further.

Object Oriented Design (OOD)

In OOD, a system is structured as interrelated objects to handle tasks.
Each object is responsible for its own state data and operations.
OOD follows a bottom-up approach.
Objects communicate through messaging.

Case Study: Automated Fire Alarm System

This case study provides a practical application example to the concepts.

Additional Topics

Covers OOP concepts like: Class, Objects, Abstraction, Encapsulation, Inheritance, and Polymorphism.
Explains general concepts of Association, Composition and Aggregation and provides examples.
Extensive details about UML Diagrams, its types, and use cases; including Use Case Diagrams, detailed analysis discussing features, and examples.
Describes various types of relationships between classes and a case study for library management system.
Comprehensive explanation of Activity Diagrams.
Detailed description of the UML diagram notation and concepts, including how various parts work together, like symbols and how to use them.
Detailed introduction and explanation of the Java program structure.
