Creating Arrays with Reference Variables

In programming languages ??such as Java and C#, an array is a basic data structure that stores multiple items of the same type. Use reference variables to efficiently manage memory and seamlessly manipulate collections of objects. This article will explore how to create an array using reference variables. Understanding reference variables Reference variables in programming do not store actual data values, but point to the memory location where the data is stored. For large data structures such as arrays, this feature has the advantage of saving memory and improving performance. Create an array using reference variables To create an array using a reference variable, the programmer first declares the type of the array and assigns it to the reference variable. Here are examples of creating arrays in Java and C#: public class ArrayExample {
