将多个“随机生成的”对象添加到ArrayList会导致多次添加相同的对象

import java.util.ArrayList;
import java.util.HashSet;
import java.util.List;

public class RandomObjectExample {
    public static void main(String[] args) {
        List<Person> personList = new ArrayList<>();
        HashSet<Person> personSet = new HashSet<>();

        // 随机生成10个Person对象
        for (int i = 0; i < 10; i++) {
            Person randomPerson = generateRandomPerson();
            
            // 检查ArrayList是否已包含相同的对象
            if (!personList.contains(randomPerson)) {
                personList.add(randomPerson);
            }
            
            // 添加对象到HashSet中，用于去重
            personSet.add(randomPerson);
        }
        
        // 添加HashSet中的对象到ArrayList中
        personList.addAll(personSet);
        
        // 打印ArrayList中的对象
        for (Person person : personList) {
            System.out.println(person);
        }
    }

    private static Person generateRandomPerson() {
        // 随机生成Person对象的逻辑
        // ...
        return new Person(name, age);
    }
}

class Person {
    private String name;
    private int age;

    // 构造函数、getter和setter方法等

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        Person person = (Person) o;
        return age == person.age && name.equals(person.name);
    }

    @Override
    public int hashCode() {
        return Objects.hash(name, age);
    }

    @Override
    public String toString() {
        return "Person{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}
