Syllabus

Introduction to Course – Java Programming

In this module, we will introduce you to the course structure, covering key concepts and objectives that will be addressed. You'll also gain insight into the tools and environments that will be used for Java programming throughout the course. This foundation will set the stage for your learning journey.

Installing Java

In this module, we will walk you through the installation process for Java on different operating systems: Windows, macOS, and Linux. Troubleshooting tips are provided to resolve any installation issues, ensuring you're ready to begin programming with Java on your system.

Introduction to Java Programming with JShell Using Multiplication Table

In this module, we will dive into JShell for interactive Java programming and use the multiplication table challenge as an exercise. Through this challenge, you will become familiar with Java expressions, variables, and learn to print outputs to the console. You'll also tackle various puzzles and exercises to enhance your understanding.

Introduction to Method with Multiplication Table

In this module, we will introduce Java methods by revisiting the multiplication table challenge. You will learn how to create methods, pass parameters, and use method overloading. Practical exercises and tips will help you deepen your understanding of Java methods.

Introduction to the Java Platform

In this module, we will explore the core components of the Java platform, including the role of javac and bytecode. You'll also take a first look at Java classes and objects, learning how to compile and run Java programs on your system.

Introduction to Eclipse - First Java Project

In this module, we will guide you through the installation process for Eclipse and show you how to set up your first Java project. You'll also become familiar with using Eclipse's features like saving actions, refactoring, and debugging to improve your programming workflow.

Introduction to Object-Oriented Programming

In this module, we will dive into the principles of Object-Oriented Programming (OOP). You will learn about classes, objects, encapsulation, and more advanced concepts like inheritance and polymorphism. Practical exercises will help reinforce these concepts through hands-on examples.

Primitive Data Types and Alternatives

In this module, we will explore Java’s primitive data types in depth, including integers, floating points, and booleans. You'll also learn about wrapper classes and how to use BigDecimal for precise calculations. Exercises and puzzles will help solidify your understanding.

Conditionals

In this module, we will focus on conditional statements, which are crucial for controlling the flow of your Java programs. You will learn how to use if-else, nested if-else, and switch statements to create decision-making logic. Practical exercises and puzzles will help you refine these skills.

Loops

In this module, you will learn how to use loops to repeat actions in your Java programs. We will cover for loops, while loops, and do-while loops. Through various exercises, you'll practice how to iterate through collections, solve puzzles, and use loops efficiently.

Reference Types

In this module, we will focus on reference types in Java, such as arrays, objects, and strings. You'll explore how reference types are stored in memory and learn the concept of immutability. Exercises and puzzles will help you gain proficiency in working with these data types.

Arrays and ArrayLists

In this module, we will explore arrays and ArrayLists, two essential data structures in Java. You will learn how to create and manipulate arrays and ArrayLists, as well as how to use them in practical exercises such as student record management.

Object-Oriented Programming Again

In this module, we will revisit object-oriented programming (OOP) concepts and expand on them with advanced topics like inheritance, abstraction, and polymorphism. Practical exercises will reinforce your skills in designing and implementing OOP solutions.

Collections

In this module, we will delve into Java collections and their importance in managing data. You will explore the different collection types like List, Set, Queue, and Map, and learn how to use classes like ArrayList, HashSet, and HashMap. Exercises will give you practical experience in manipulating and sorting data with collections.

Generics

In this module, we will introduce generics, a powerful feature in Java that enables type safety. You will learn how to create generic classes and methods, as well as how to use wildcards and define upper and lower bounds. Exercises will help you practice using generics effectively in your code.

Introduction to Functional Programming

In this module, we will explore functional programming concepts in Java, such as lambda expressions and streams. You will learn how to use these tools to process data in a more declarative way. Practical exercises will help you master functional programming techniques and solve real-world problems efficiently.

Introduction to Threads and Concurrency

In this module, we will explore threads and multi-threading in Java. You'll learn how to create and manage threads, use synchronization for thread safety, and leverage concurrency utilities like ExecutorService. Exercises will help you understand the practical applications of multi-threading in Java programs.

Introduction to Exception Handling

In this module, you will learn how to handle exceptions in Java using try-catch blocks. We will cover checked versus unchecked exceptions and introduce the concept of custom exceptions. Exercises will help you practice exception handling techniques and understand the importance of robust error handling.

Files and Directories

In this module, you will learn how to work with files and directories in Java. We will cover how to list files, read from and write to files, and filter directories. Practical examples will help you understand how to handle file operations efficiently.

More Concurrency with Concurrent Collections and Atomic Operations

In this module, we will build upon the concurrency concepts introduced earlier and delve deeper into synchronized blocks, locks, and atomic operations. You will also explore concurrent collections and their use in multi-threaded programming.

Java Tips

In this module, you will discover various tips and best practices to enhance your Java programming skills. From working with static methods and final variables to using enums, this section will help you write cleaner, more efficient Java code.
