比较两个对象,java

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

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

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    @Override
    public int compareTo(Person other) {
        if (this.age< other.age) {
            return -1;
        } else if (this.age == other.age) {
            return 0;
        } else {
            return 1;
        }
    }
}

Person person1 = new Person("Alice", 25);
Person person2 = new Person("Bob", 30);

int result = person1.compareTo(person2);
if (result < 0) {
    System.out.println("Person1 is younger than Person2");
} else if (result == 0) {
    System.out.println("Person1 is the same age as Person2");
} else {
    System.out.println("Person1 is older than Person2");
}

Person1 is younger than Person2
