Comparator Interface

The Comparator interface in programming allows you to define how to compare two objects to determine their order. Think of it as a custom sorting rule—you can specify whether objects should be sorted by size, date, or any other attribute. Instead of relying on default comparisons, a Comparator offers a way to control the sorting logic, making it flexible to order objects in various ways. It’s commonly used when sorting collections, such as lists or arrays, based on specific criteria determined by the programmer.
