Multi-Dimensional Arrays

Multi-Dimensional Arrays : 

• Multi-dimensional arrays in Java allow you to create arrays of arrays, forming a structure where each element is itself an array.
• They provide a way to represent tables or matrices with rows and columns.
• In Java, you can create two-dimensional arrays, three-dimensional arrays, or even higher dimensions as needed.

Here are some common uses of Multi-Dimensional Arrays in  real-life scenarios : 

• Image Processing
• Matrices and Linear Algebra
• Games and Graphics
• Database Systems
• AI and Machine Learning

Two-Dimensional Array :

A two-dimensional array in Java is an array of arrays. It's like a table with rows and columns.

Declaration and Initialization:

• dataType represents the type of elements the array will hold.
• rows indicate the number of arrays or "rows" in the 2D array.
• columns indicate the number of elements in each "row."

Example:

Accessing Elements:

Accessing elements in a two-dimensional array involves using two indices: one for the row and another for the column.

Three-Dimensional Arrays and Beyond:

You can extend this concept to three-dimensional arrays and beyond, creating arrays of arrays of arrays. For instance, a three-dimensional array is like a cube, with layers of rows and columns.

Declaration and Initialization of a 3D array:

Example of a 3D array:

The concept extends further for higher dimensions, creating arrays of arrays of arrays, and so on.
