Hello, and welcome back! Our journey today takes us into the sorting universe in Java. We will learn about and use Java's built-in Arrays.sort() function. Additionally, we will explore how Java's Comparator interface allows us to define custom sorting rules for more complex sorting scenarios.

These ready-to-use tools in Java simplify the task of sorting significantly. Let's get started!

Sorting refers to arranging data in a specific order, which enhances the efficiency of search or merge operations on data. In real life, we sort books alphabetically or clothes by size. Similar concepts are applicable in programming, where sorting large lists of data for more effective analysis is a frequent practice.

Java offers a built-in sorting method, Arrays.sort(), to sort arrays. Here's a demonstration of how we use this method:

Sorting with Arrays.sort() makes sorting arrays of primitives a breeze. Let's see it in action!
