如何调用完全初始化的构造函数

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;
    }

    // Getter 和 Setter 方法
    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;
    }
}

// 调用构造函数创建对象
public class Main {
    public static void main(String[] args) {
        // 使用无参构造函数创建对象
        Person person1 = new Person();
        System.out.println("Name: " + person1.getName() + ", Age: " + person1.getAge());

        // 使用有参构造函数创建对象
        Person person2 = new Person("Alice", 30);
        System.out.println("Name: " + person2.getName() + ", Age: " + person2.getAge());
    }
}
