用java编写一个person类,包括姓名、性别、年龄、子女等属性，并封装了获得姓名、获得年龄、增加一岁、获得子女、设置子女等方法。子女属性为一个Person数组。

### 回答1：

public class Person {
    private String name;
    private String gender;
    private int age;
    private Person[] children;

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

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public void addYear() {
        age++;
    }

    public Person[] getChildren() {
        return children;
    }

    public void setChildren(Person[] children) {
        this.children = children;
    }
}

### 回答2：
Person类的示例代码如下所示：

public class Person {
    private String name;
    private String gender;
    private int age;
    private Person[] children;

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

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public void increaseAge() {
        age++;
    }

    public Person[] getChildren() {
        return children;
    }

    public void setChildren(Person[] children) {
        this.children = children;
    }

    public static void main(String[] args) {
        Person child1 = new Person("Child1", "Male", 10);
        Person child2 = new Person("Child2", "Female", 8);

        Person[] children = {child1, child2};

        Person parent = new Person("Parent", "Male", 35);
        parent.setChildren(children);

        System.out.println("Parent's name: " + parent.getName());
        System.out.println("Parent's age: " + parent.getAge());

        parent.increaseAge();
        System.out.println("After increasing age, Parent's age: " + parent.getAge());

        System.out.println("Parent's children: ");
        for (Person child : parent.getChildren()) {
            System.out.println("Child name: " + child.getName() + ", Child age: " + child.getAge());
        }
    }
}

这个Person类有姓名、性别、年龄、子女等属性，并且提供了获取姓名、获取年龄、增加一岁、获取子女、设置子女等方法。子女属性为一个Person数组。在示例代码中，我们创建了两个子女对象child1和child2，然后使用这两个子女对象初始化了一个子女数组children，然后创建了一个父母对象parent，并将子女数组设置为父母对象的子女属性。最后，我们使用该对象的一些方法进行测试并输出结果。

### 回答3：

public class Person {
    private String name;
    private String gender;
    private int age;
    private Person[] children;

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

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public void increaseAge() {
        age++;
    }

    public Person[] getChildren() {
        return children;
    }

    public void setChildren(Person[] children) {
        this.children = children;
    }
}

以上是一个用Java编写的`Person`类，包括姓名、性别、年龄、子女等属性，并封装了获得姓名、获得年龄、增加一岁、获得子女、设置子女等方法。子女属性为一个Person数组。在构造方法中，通过参数传入姓名、性别、年龄，并通过对应的get和set方法来获取和设置对应的属性值。增加一岁的方法`increaseAge()`会将年龄加1。子女属性`children`可以通过`getChildren()`方法获取，通过`setChildren()`方法设置。
