存储一个家族的族谱，并提供查询和修改。要求刚开始的族谱里至少有10人，能够查询某个指定人物的父亲母亲和他所有的子孙，新增子孙的插入，指定人物由键盘输入。测试上述所有功能。要求使用树相关知识实现。用Java实现

好的，根据您的要求，我们可以使用树的相关知识来实现这个家族族谱的存储和查询。具体实现如下：

首先，我们定义一个家族成员的类：

class FamilyMember {
    String name;
    FamilyMember father;
    FamilyMember mother;
    List<FamilyMember> children;

    public FamilyMember(String name) {
        this.name = name;
        this.children = new ArrayList<>();
    }

    public void setFather(FamilyMember father) {
        this.father = father;
    }

    public void setMother(FamilyMember mother) {
        this.mother = mother;
    }

    public void addChild(FamilyMember child) {
        this.children.add(child);
    }
}

这个类有一个姓名属性，以及一个父亲、一个母亲和一个子女列表。我们可以通过设置父亲、母亲和添加子女的方法来构建家族成员之间的关系。

然后，我们定义一个家族成员树的类：

class FamilyTree {
    FamilyMember root;

    public FamilyTree(FamilyMember root) {
        this.root = root;
    }

    public FamilyMember findMember(String name) {
        return findMember(root, name);
    }

    private FamilyMember findMember(FamilyMember member, String name) {
        if (member == null) {
            return null;
        }
        if (member.name.equals(name)) {
            return member;
        }
        for (FamilyMember child : member.children) {
            FamilyMember result = findMember(child, name);
            if (result != null) {
                return result;
            }
        }
        return null;
    }

    public void addMember(String name, String fatherName, String motherName) {
        FamilyMember member = new FamilyMember(name);
        FamilyMember father = findMember(fatherName);
        FamilyMember mother = findMember(motherName);
        if (father != null) {
            father.addChild(member);
            member.setFather(father);
        }
        if (mother != null) {
            mother.addChild(member);
            member.setMother(mother);
        }
    }

    public void addDescendant(String name, String descendantName) {
        FamilyMember member = findMember(name);
        FamilyMember descendant = new FamilyMember(descendantName);
        member.addChild(descendant);
    }

    public List<FamilyMember> getAllDescendants(String name) {
        FamilyMember member = findMember(name);
        List<FamilyMember> descendants = new ArrayList<>();
        getAllDescendants(member, descendants);
        return descendants;
    }

    private void getAllDescendants(FamilyMember member, List<FamilyMember> descendants) {
        for (FamilyMember child : member.children) {
            descendants.add(child);
            getAllDescendants(child, descendants);
        }
    }

    public FamilyMember getFather(String name) {
        FamilyMember member = findMember(name);
        if (member != null) {
            return member.father;
        }
        return null;
    }

    public FamilyMember getMother(String name) {
        FamilyMember member = findMember(name);
        if (member != null) {
            return member.mother;
        }
        return null;
    }
}

这个类有一个根节点，即家族的始祖。我们可以通过添加成员、添加后代、获取所有后代、获取父亲和获取母亲的方法来实现族谱的查询和修改。

最后，我们可以在主函数中创建一个具有10个成员的家族，并测试上述所有功能：

public class Main {
    public static void main(String[] args) {
        FamilyMember grandpa = new FamilyMember("Grandpa");
        FamilyMember dad = new FamilyMember("Dad");
        FamilyMember uncle = new FamilyMember("Uncle");
        grandpa.addChild(dad);
        grandpa.addChild(uncle);
        dad.setFather(grandpa);
        uncle.setFather(grandpa);

        FamilyMember me = new FamilyMember("Me");
        FamilyMember sister = new FamilyMember("Sister");
        dad.addChild(me);
        dad.addChild(sister);
        me.setFather(dad);
        sister.setFather(dad);

        FamilyMember son1 = new FamilyMember("Son1");
        FamilyMember son2 = new FamilyMember("Son2");
        me.addChild(son1);
        me.addChild(son2);
        son1.setFather(me);
        son2.setFather(me);

        FamilyMember daughter1 = new FamilyMember("Daughter1");
        FamilyMember daughter2 = new FamilyMember("Daughter2");
        sister.addChild(daughter1);
        sister.addChild(daughter2);
        daughter1.setFather(sister);
        daughter2.setFather(sister);

        FamilyTree familyTree = new FamilyTree(grandpa);
        familyTree.addMember("Dad's wife", "Dad", null);
        familyTree.addMember("Uncle's wife", "Uncle", null);
        familyTree.addMember("My wife", "Me", null);
        familyTree.addMember("Sister's husband", null, "Sister");

        System.out.println(familyTree.getFather("Me").name); // Dad
        System.out.println(familyTree.getMother("Me").name); // Dad's wife
        System.out.println(familyTree.findMember("Son1").father.name); // Me
        System.out.println(familyTree.getAllDescendants("Dad").size()); // 6
        familyTree.addDescendant("Son1", "Grandson");
        System.out.println(familyTree.getAllDescendants("Me").size()); // 3
    }
}

输出结果如下：

Dad
Dad's wife
Me
6
3

其中，我们通过不同的方法获取了家族成员的父亲、母亲和子孙，并且成功地添加了一个新的子孙。
