TOP 5 Things to know about JAVA Array:
Fixed Size: Java arrays have a fixed size, meaning once you declare an array with a specific size, you cannot change it during runtime. To overcome this limitation, dynamic data structures like ArrayLists are often used.
Homogeneous Elements: Java arrays can only store elements of the same data type. For example, if you declare an array of integers, it can only hold integer values.
Zero-Based Indexing: Array indices in Java start from 0. The first element is accessed using index 0, the second with index 1, and so on. This is a common indexing convention in many programming languages.
Length Property: You can find the length of an array using the length property. For example, if arr is an array, you can obtain its length by calling arr.length.
Multidimensional Arrays: Java supports multidimensional arrays, allowing you to create arrays of arrays. Commonly used are 2D arrays, which can be visualized as a grid with rows and columns. Accessing elements in a 2D array involves specifying both row and column indices.
