Java TreeSet Tutorial: Exploring the floor() Method | Java Collection Framework

Welcome to our Java Collections tutorial series! In this video, we'll explore the `floor()` method in TreeSet within the Java Collection Framework. TreeSet is a versatile data structure that implements the Set interface and maintains elements in sorted order, making it an ideal choice for scenarios where you require a sorted collection of unique elements.

**What You'll Learn:**
- Introduction to the TreeSet class and its functionalities
- Explanation of the `floor()` method and its significance in TreeSet
- Practical demonstrations and examples illustrating how to utilize the `floor()` method to retrieve the greatest element in the TreeSet that is less than or equal to the given element
- Insight into the behavior of the `floor()` method under various circumstances and edge cases
- Best practices for effectively incorporating the `floor()` method into your Java applications
- Tips on handling and utilizing the element returned by the `floor()` method

**Why This is Important:**
The `floor()` method in TreeSet provides a convenient way to retrieve the greatest element in the sorted set that is less than or equal to the given element, enhancing the flexibility and efficiency of working with TreeSet. Proficiency in leveraging the `floor()` method empowers you to optimize your code and efficiently handle scenarios where you need to find the preceding or equal element.

hello sir! how will the floor method work if we are using it with a user class, say a pair class that takes in two integers? and the pair class implements a comparable interface with method compareTo() that compares the first integer. thank you very much!
