如何正确处理构造函数参数

public class Person {
    private String name;
    private int age;

    // 无参构造函数
    public Person() {
        this.name = "Unknown";
        this.age = 0;
    }

    // 有参构造函数
    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    // Getters and Setters
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

public class PersonParams {
    private String name;
    private int age;
    // 其他参数...

    // Getters and Setters
}

public class Person {
    private String name;
    private int age;

    public Person(PersonParams params) {
        this.name = params.getName();
        this.age = params.getAge();
        // 初始化其他属性...
    }
}

public Person(String name, int age) {
    if (name == null || name.isEmpty()) {
        throw new IllegalArgumentException("Name cannot be null or empty");
    }
    if (age < 0) {
        throw new IllegalArgumentException("Age cannot be negative");
    }
    this.name = name;
    this.age = age;
}

public Person(String name) {
    this(name, 0); // 默认年龄为0
}
