This is the repository for the LinkedIn Learning course Java Cheat Codes: Most Popular Functions. The full course is available from LinkedIn Learning.

Java methods (also known as Java functions) allow you to write cleaner, more concise code and solve common programming tasks. Many Java beginners struggle to memorize and effectively utilize the vast array of methods available in the Java library. In this course, engineer and instructor Semirah Dolan provides a focused and practical approach to learning the most popular and versatile Java methods, empowering you to write cleaner, more concise code and solve common programming tasks with confidence.

This course includes Code Challenges powered by CoderPad. Code Challenges are interactive coding exercises with real-time feedback, so you can get hands-on coding practice alongside the course content to advance your programming skills.

See the readme file in the main branch for updated instructions and information.

This repository has branches for each of the videos in the course. You can use the branch pop up menu in github to switch to a specific branch and take a look at the course at that stage, or you can add /tree/BRANCH_NAME to the URL to go to the branch you want to access.

The branches are structured to correspond to the videos in the course. The naming convention is CHAPTER#_MOVIE#. As an example, the branch named 02_03 corresponds to the second chapter and the third video in that chapter. Some branches will have a beginning and an end state. These are marked with the letters b for "beginning" and e for "end". The b branch contains the code as it is at the beginning of the movie. The e branch contains the code as it is at the end of the movie. The main branch holds the final state of the code when in the course.
