Mastering Array Lists and 2D Arrays: Adding, Searching, and Sorting in Java Class 31 | Part 3
In this comprehensive AP Computer Science A tutorial, we delve deep into essential Java concepts including working with ArrayLists, handling 2D arrays, and optimizing your code with loops. We begin by automating the process of adding elements to an ArrayList using both for and while loops, and then explore how to read and manipulate data efficiently. You'll also learn how to modify a selection sort algorithm to work with ArrayLists of strings, utilize the compareTo method for sorting, and understand how to implement linear and sequential search methods. Perfect for pre-university students aiming to solidify their understanding of Java basics and advanced techniques!
