What are 'Arrays' ?
An Array is known as the collection of Similar data types.
An Array is actually a data structure which consists of a group of elements of same type.
Arrays store same type of elements in consecutive memory location one after another.
Examples :-Â
Suppose there is an array which consists of 5 Elements of integer type let's say the elements are 4,6,2,7,9.
So, if in the above array the address of the memory location of the element 4 is 'a123480' then the address of the memory location of the next element 6 will be 'a123481' and that of the next element i.e. 2 will be 'a123482' and further elements will be followed.

9Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 'a123484'
Now let's dig into how to declare and create an array in Java programming language:Â
Syntax:
Now Lets see an example of Array in Java:
package com.company;
import java.util.*;
public class Main
{
public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
System.out.println("Enter the Size of Array");
int n = sc.nextInt();
// declaring array
int[] arr = new int[n];
// for loop to take the array elements from the user
System.out.println("Enter the elements of Array");
for (int i=0; i<n;i++)
{
arr[i] = sc.nextInt();
}
// printing the array elements
System.out.println("The Inputed values are :-");
for (int i=0;i<n;i++)
{
System.out.println(arr[i]);
}
}
}Output For Java
