Course Description

Build real-world Java skills by working hands-on with file management, data collections, and custom methods. This course helps you move beyond the basics to write cleaner, more efficient, and maintainable Java code.

Work with Files and Directories in Java

Start by learning how to create, delete, and check files. You’ll read and write text using file-handling tools and manage directories and file paths to organize data effectively.

Process and Transform Data with Java Collections

Next, explore how to handle collections of data in Java. You’ll safely loop through lists, modify elements, and use modern techniques to filter, transform, and summarize data using a functional approach.

Write Reusable Java Code with Methods, Dates, and Enums

Finally, you’ll build custom methods to solve common problems, work with dates and times, and use enums to represent fixed sets of values. You'll apply recursion and clean coding practices to write flexible, reusable Java programs.

What You’ll Achieve

By the end of the course, you’ll have the skills to manage files, process data collections, and create scalable, maintainable Java applications with confidence.
