我为家谱写了这个树类

现在我需要一种搜索​​方法来在我的树中找到一个节点

它是一个 n 叉树,每个节点可以有 0 到 n 个子节点

搜索方法可以搜索一个节点或两个名称,包括节点名称和他/她的父亲名称

请帮帮我

public class FamilyNode {
 public String name;
 public String sex;
 public FamilyNode Father;
 public FamilyNode Mother;
 public FamilyNode Spouse=null;
 public String status="alive";
 public int population;
 public ArrayList<FamilyNode> children=new ArrayList<FamilyNode>() ;


public FamilyNode(String name1,String sex1){
this.name=name1;
this.sex=sex1;
this.population=this.children.size()+1;
}
public void SetParents(FamilyNode father,FamilyNode mother){
    this.Father=father;
    this.Mother=mother;
    }
public void SetHW(FamilyNode HW){
    this.Spouse=HW;
}
public void AddChild(FamilyNode child){
    child.SetParents(this.Father, this.Spouse);
    this.children.add(child);
    this.Spouse.children.add(child);
}

public int Number (){
   int number_of_descendants = this.population;
   if(this.Spouse!=null) number_of_descendants++;
for(int index = 0; index < this.children.size(); index++)
number_of_descendants = number_of_descendants+ this.children.get(index).Number();
return number_of_descendants;
}

}

看看树遍历算法。本文很好地介绍了它们(使用递归和出队)这是遍历树的一种方法

public class FamilyNode {
    // ...
    // ...
    public void traverseNode(){
       if(name.equals("NameWeAreLookingFor")){
          // We found a node named "NameWeAreLookingFor"
          // return here if your are not interested in visiting children
       } 
       for(FamilyNode child : node.children){
            child.traverseNode();
       }
    }
}

要遍历所有树,请执行以下操作:

FamilyNode root = ...;
root.traverseNode();

请注意,此方法使用递归。如果你的树很大,那么我建议你改用队列,因为递归可能会导致 StackOverFlow 异常。
