In this module, we will dive into the world of string operations in Java. You will learn how to manipulate strings by performing common tasks such as comparison, search, slicing, and replacing. Additionally, we will explore string conversion techniques to equip you with the tools to handle text-based data in Java.

In this module, we will explore object-oriented programming (OOP) principles in Java, focusing on classes, objects, and methods. You will learn to leverage the power of encapsulation, method overloading, and constructors to design well-structured programs, with a focus on enhancing code organization and readability.

In this module, we will explore several special classes in Java that are essential for advanced programming. You’ll become familiar with the Math and StringBuilder classes, handle random number generation, and discover how to work with UUIDs. This knowledge will enhance your ability to manage data and interact with users.

In this module, we will explore the new features and improvements introduced in Java 10. We will focus on the new "var" keyword for local variable type inference and discuss updates to the garbage collector. You'll also learn about additional enhancements that make Java 10 an even more powerful tool for developers.

In this module, we will introduce you to inheritance and abstraction, core concepts of object-oriented programming. You will learn how to extend classes, override methods, and implement interfaces, while exploring polymorphism and how to effectively use the "final" keyword to enhance your designs.

In this module, we will dive into Java’s array handling capabilities. You’ll learn how to create, iterate, and manipulate both single-dimensional and multi-dimensional arrays. We’ll also explore advanced array concepts like arrays of objects, helping you manage and process data efficiently.

In this module, we will focus on Java’s List interface, specifically ArrayList and LinkedList. You’ll learn how to use ArrayLists to store dynamic collections of objects and how to iterate over these lists. We’ll also discuss the key differences between ArrayList and LinkedList to help you select the right structure for your program.

In this module, we will cover Java’s Set and Map collections. You’ll learn how to store unique elements using different types of sets, and how to efficiently manage key-value pairs with maps. Practical exercises will help you understand how to iterate through these collections and apply them in real-world scenarios.

In this module, we will introduce you to the power of Regular Expressions (RegEx) in Java. You will learn how to use RegEx to find and manipulate text based on patterns. With practical examples, we’ll show you how to create and use regular expressions to handle complex text matching tasks.

In this module, we will guide you through Java's exception handling mechanisms. You’ll learn how to properly handle errors and exceptions using try-catch blocks and the “finally” block. We’ll also cover custom exception handling techniques to make your programs more resilient to unexpected errors.

In this module, we will explore Java 8’s Date and Time API for handling time-based data. You will learn how to manipulate dates and times, calculate time differences, and format your output. Practical exercises will show you how to customize and present date-time values effectively in your applications.

In this module, we will introduce you to Apache Commons IO, a library that simplifies file handling in Java. You will learn how to read, write, and manipulate text files, as well as perform advanced tasks like sorting lines and removing duplicates. We’ll also tackle common interview questions related to text file processing.

In this module, we will dive into Apache POI, a library used for handling Excel files in Java. You will learn how to read and write data from Excel sheets, process it into 2D arrays, and manipulate the data programmatically. We’ll also cover common challenges and interview questions related to Excel file handling.
