How does Java know which object is bigger or smaller? What exactly does compareTo() return and why? This video answers everything from first principles — so you don’t just memorize, you actually understand. What You’ll Learn: Why Comparable interface is needed Problem with sorting custom objects How compareTo() works internally Understanding return values (+ve, -ve, 0) Ascending vs Descending sorting logic Why returning 0 can be dangerous Real examples with custom classes How Collections.sort() uses Comparable Introduction to Collections utility class Why Learn Java? Java is one of the most powerful and widely used programming languages in the world. It is used in: Backend development Enterprise applications Android development Banking systems Large-scale distributed systems If you want to master Data Structures, Spring Boot, Microservices, or System Design, Java fundamentals are essential.
