Type of Arrays in Java

The Java array is divided into two main types which then expands in different varieties of arrays. Here's a breakdown of the type of arrays:

1. Regular Array: Regular array is further divided into 1-dimensional, 2- 2-dimensional, 3-dimensional arrays, and so on.

2. Jagged Array: Jagged is an array of arrays such that member arrays can be of different sizes, i.e., we can create 2-D or 3-D arrays but with a variable number of columns in each row. These types of arrays are also known as Jagged arrays.

One-Dimensional (1D) Array

A 1D array is a list of elements stored in a single row. It is used to store multiple values of the same type in a linear format.

Syntax:

dataType[] arrayName = new dataType[size];

or

dataType[] arrayName = {value1, value2, value3, ...};

Example:

A list of students in a single class.

class MasterBackend {
    public static void main(String[] args) {
        // 1D Array: Students in a single class
        String[] students = {"Ayush", "Rahul", "Neha", "Priya"};

        System.out.println("Students in a class:");
        for (String student : students) {
            System.out.println(student);
        }
    }
}

Output:

Students in a class:
Ayush
Rahul
Neha
Priya
