java语言，编写一个person类，包括人的姓名，性别，年龄，子女等属性，并封装有获得姓名，获得年龄，增加一岁，获得子女，设置子女等方法，其中子女为一个person数组，用某实际数据测试该类的设计

好的，下面是Java代码实现：

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 addAge() {
        age++;
    }

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

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

我们可以使用以下代码进行测试：

public class TestPerson {
    public static void main(String[] args) {
        Person mother = new Person("Mary", "Female", 30);
        Person father = new Person("John", "Male", 35);
        Person child1 = new Person("Tom", "Male", 5);
        Person child2 = new Person("Lily", "Female", 3);
        Person[] children = {child1, child2};

        mother.setChildren(children);
        father.setChildren(children);

        System.out.println("Mother's name: " + mother.getName());
        System.out.println("Father's age: " + father.getAge());

        child1.addAge();
        System.out.println("Child1's age: " + child1.getAge());

        Person[] childrenOfMother = mother.getChildren();
        System.out.println("Children of mother: ");
        for (Person child : childrenOfMother) {
            System.out.println(child.getName());
        }
    }
}

输出结果为：

Mother's name: Mary
Father's age: 35
Child1's age: 6
Children of mother: 
Tom
Lily

以上就是一个简单的Person类的实现和测试。
