Можете объяснить, что означает интерфейс Comparable в Java и какую роль он играет при сравнении объектов?

The Comparable interface in Java defines the compareTo() method, which allows objects to be compared to each other for ordering.

It plays a key role in sorting and searching, as it allows defining the natural order of objects. The compareTo() method returns:

• a negative number if the current object is less than the other,
• zero if the objects are equal,
• a positive number if the current object is greater than the other.

Example:

public class Person implements Comparable<Person> {
    private String name;
    private int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    @Override
    public int compareTo(Person other) {
        return Integer.compare(this.age, other.age);
    }
}

Here, Person objects are compared by age, which allows, for example, sorting a list of people by age.
