Learning track content

Module 1 / Java Basics

Discover the unique features of Java and understand why it's a recommended programming language to learn. Write your first Java code and explore how to print text to the console.

Learn the basics of programming, dive into primitive data types, and explore operations with them. Write code that performs mathematical tasks and evaluates conditions for seamless execution.

Explore various loops such as for, while, and do-while, which are essential in any programming language. Loops enable efficient iteration over large datasets, saving significant time. Apply them extensively in tasks like sorting, working with arrays, collections, and more.

Learn how to effectively use arrays in Java programming by discovering how to group data into arrays and exploring common methods and properties for working with them. Techniques for manipulating and optimizing arrays in real-world applications will also be examined.

Learn about String, a crucial data type in Java, and discover its many built-in methods and operations. Explore String and StringBuilder, understanding their basic methods and how to use strings effectively in Java.

Module 2 / Mastering Java Application Configuration

Learn the fundamentals of Java properties files, their structure, and how they are used for application configuration.

Dive into Java's system properties and environment variables, and learn how to use them for flexible and dynamic configuration.

Master advanced configuration patterns, including layered configuration, profiles, and integration with build tools.

Module 3 / Getting Started with java.util Library

Learn the basics of Java syntax, variables, data types, and control flow to build a strong foundation for using the java.util library.

Dive into the core java.util collections: Lists, Sets, and Maps. Learn how to store, retrieve, and manipulate groups of data efficiently.

Explore essential utility classes in java.util, such as Collections, Random, and Date, to simplify common programming tasks.

Learn how to handle exceptions and configure Java applications using properties and environment variables.
