Java – Read Array Size and create object:

import java.util.Scanner; class Code {             public static void main(String[] args)             {                         Scanner scan = new Scanner(System.in);                                                 System.out.print(“Enter array size : “);                         int n = scan.nextInt();                           int[] arr = new int[n];                         System.out.println(“Array created with specified length”);             } }
