The Arrays class in java.util is a utility class that provides static methods to perform operations like sorting, searching, comparing, and converting arrays.

Java arrays can hold both primitive types (like int, char, boolean, etc.) and objects (like String, Integer, etc.) When we use arrays of primitive types, the elements are stored in contiguous locations. For non primitive types, references to items are stored at contiguous locations. After creating an array, its size is fixed; we can not change it. ... public class Geeks{ public static void main(String[] args){ // Primitive array int[] arr = {10, 20, 30, 40}; int n = arr.length; System.out.print("Primitive Array -> "); for (int i = 0; i < n; i++) System.out.print(arr[i] + " "); System.out.println(); // Non-primitive array (String objects) String[] names = {"Lakshit", "Rahul", "Pankaj"}; System.out.print("Non-Primitive Array -> "); for (int i = 0; i < names.length; i++) System.out.print(names[i] + " "); } }
