Types of Array In Java

 In Java, there are several types of arrays that can be used to store and manipulate collections of data. These include:

  1. One-dimensional arrays: This is the simplest form of an array, where all the data is arranged in a single row. Each element in the array is accessed by its index, which starts from 0.

  2. Two-dimensional arrays: This type of array is used to store data in a grid or matrix format. It is composed of rows and columns, and each element is accessed by its row and column indices.

  3. Multi-dimensional arrays: These are arrays with more than two dimensions, used to store data in higher dimensions than 2D.

  4. Jagged arrays: This is a type of two-dimensional array where each row can have a different length. This can be useful in situations where data is not uniform across the rows.

  5. Arrays of objects: In Java, arrays can also store objects of a particular class. For example, an array of String objects can be created to store a collection of strings.

  6. Arrays of primitive data types: These arrays are used to store collections of primitive data types such as integers, doubles, and booleans.

  7. Dynamic arrays: These are arrays that can dynamically resize themselves when elements are added or removed from them. In Java, the ArrayList class is an example of a dynamic array
