Compare Objects by Multiple Fields

To compare objects by multiple fields in Java using a Custom Comparator, you can follow this approach, Suppose you have a class MyClass with fields field1, field2, and field3. You want to compare objects of this class first by field1, then by field2, and finally by field3.

Let’s consider a scenario where you have a `Person` class with fields `name`, `age`, and `city`. We want to compare `Person` objects first by name, then by age, and finally by city.

Person Class:

public class Person {
    private String name;
    private int age;
    private String city;
    // Constructors, getters, and setters
}

In Java, A comparator interface is used to order the objects of user-defined classes. A comparator object is capable of comparing two objects of the same class. In this article, we will learn how to compare objects by multiple fields.
