The course is broken down into several modules that cover different tools and topics. The first module introduces the concept of code quality and explains why it's important in the software development industry. It also covers how to set up the environment for the course, which includes downloading IntelliJ IDEA and cloning the project from GitHub.
The second module covers the basics of unit testing and how to write tests for the code. The instructor explains the importance of testing and walks through how to write simple tests using JUnit. She also covers how to perform code coverage analysis to make sure that all the code is tested.
The third module focuses on using the Java Stream API to simplify code and make it more readable. Trisha explains the basics of the Stream API and how to use it to filter, transform, and aggregate data in collections. She also covers common mistakes that programmers make when using the Stream API and how to avoid them.
The fourth module covers refactoring techniques that can be used to improve the quality of the code. Trisha explains how to use IntelliJ IDEA's refactorings to improve code readability, remove duplication, and simplify logic. She also covers how to identify and refactor code smells using tools like IntelliJ IDEA and SonarLint.
The fifth module covers the use of Java 8 features such as lambdas and method references to simplify code and make it more expressive. Trisha covers the basics of functional programming and how to use Java 8 features to write cleaner and more concise code. She also covers how to use IntelliJ IDEA's inspections and quick-fixes to refactor code to use Java 8 features.
The sixth and final module covers using static analysis tools to find and fix code issues. Trisha covers the basics of static analysis and how to use tools like SonarLint and IntelliJ IDEA's inspections to find code smells, bugs, and potential issues. She also covers how to fix issues using IntelliJ IDEA's quick-fixes and how to write custom inspections.
Throughout the course, Trisha uses a sample project to demonstrate the concepts and techniques covered in each module. She explains each step in detail and provides tips and best practices for using the tools and techniques effectively. The course also includes quizzes and exercises to test your knowledge and reinforce the concepts covered in each module.
Overall, Refactoring to Modern Java is an excellent course for any Java developer who wants to improve the quality of their code and learn modern programming practices and tools.
