This is Part 2 of the Arrays. In Part 1, we learned array syntax, declaration, and traversal. In this video, we go much deeper. We will understand: • Why arrays are stored in contiguous memory • How arrays are allocated in Heap memory • What happens inside JVM when you create an array • Stack vs Heap memory for arrays • How memory indexing actually works • Why array access is O(1) • Performance implications of arrays • What really happens when you write new int[5] If you want to understand Java beyond surface-level syntax, this lecture is essential. This is not just coding. This is internal understanding. 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.
