Java Programming

Overview

This course introduces learners to Java programming, covering essential topics from basic syntax to advanced features. Students will start with the fundamentals such as variables, data types, and decision-making constructs before moving into more complex areas like object-oriented programming, collections, and file handling. Practical exercises reinforce each concept, helping students build real-world applications. The course culminates in a mini-project where students develop an inventory management system, integrating all learned concepts.

Objectives

• Understand the fundamentals of Java including variables, data types, operators, and control structures.
• Develop proficiency in creating and using methods, arrays, and strings in Java.
• Learn core OOP principles such as encapsulation, inheritance, and polymorphism.
• Gain experience with exception handling, collections, and file operations in Java.

Key topics

• Introduction to Java and its architecture
• Object-oriented programming concepts
• Collections framework and file handling
• Multithreading and Java 8 features

Expected outcomes

• Build and run basic Java programs using the JDK environment and IDEs like IntelliJ IDEA or Eclipse.
• Design and implement object-oriented solutions using classes, objects, and inheritance.
• Create efficient applications using advanced Java features like streams, lambda expressions, and multithreading.
