Arrays in Java Explained | Single, Multi-Dimensional & Dynamic Arrays | Java Tutorial | Ch12

In this Java tutorial, we explore one of the most important foundations of programming — Arrays in Java.

Arrays help us store and organize multiple values efficiently using a single variable, making our programs cleaner, faster, and easier to manage.

In this chapter, you’ll learn:
● What are arrays in Java?
● Single-dimensional arrays
● Multi-dimensional arrays
● Jagged arrays
● Static arrays
● Dynamic arrays using ArrayList
● Array declaration & initialization
● Array indexing
● Array traversal using loops
● Best practices while working with arrays

We’ll understand how arrays work internally, when to use different types of arrays, and common mistakes beginners should avoid while handling data structures in Java.
