In this module, we will delve into the various primitive data types available in Java, such as integers, floating point numbers, Booleans, and characters. You will practice casting, conversion, and accuracy, and work with BigDecimal for precise calculations.

In this module, we will explore the use of conditionals in Java programming, including if-else and switch statements. Through a series of puzzles and exercises, you will learn to implement and optimize conditional logic in your code.

In this module, we will cover the fundamentals of looping structures in Java, including for, while, and do-while loops. You will engage in exercises that reinforce loop syntax and usage, and learn to select the best loop for different coding tasks.

In this module, we will investigate Java reference types, including how they are stored in memory. You will work with strings and their methods, understand immutability, and explore alternatives like StringBuffer and StringBuilder. Additionally, you will learn about wrapper classes and date-time manipulation.

In this module, we will focus on arrays and ArrayLists in Java, starting with the basics and moving towards more complex manipulations. You will engage in exercises that involve creating, accessing, and modifying arrays and ArrayLists, and understand their importance in Java programming.

In this module, we will revisit object-oriented programming concepts, delving deeper into class design, inheritance, and polymorphism. You will learn to design complex classes, understand object composition, and differentiate between abstract classes and interfaces through practical examples and exercises.
