Build a strong foundation of knowledge in Java programming! In this lesson we take a look at lists and their application!

By now you’ve learned all about arrays, but did you know there are more data structures in programming? Lists are one of the most popular data structures in programming, as they allow for flexibility. Unline arrays, their length is not fixed and you can insert and delete elements at any point! Cool, right?

As always, we advise you to pause the video right before the solving part of a problem and try to do the exercises on your own first. Then, if you have difficulties, just watch the provided solutions in the video. If you still have questions, we’re always here to help! Join our Facebook group and ask away!

*The exercise descriptions are to be found in the PDF document at the end of this post.

If you are new to programming, make sure to watch the Free Full Java Basics course first, as it is a necessary prerequisite to this one. It explains the topics in a lot more detail, as this video aims to revise them and get to more complex topics after that.
This course is also perfect for people who have some background in programming with a different language and would like to pick up on Java.
