我写了这个 n 数组树类。我想编写一个方法来将子节点添加到树中的特定节点。
首先,我应该搜索我的树以找到父亲,然后将孩子添加到该节点孩子。我不知道我应该如何声明我的方法
public class FamilyNode {
public String name;
public String Family;
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 firstname,String lastname,String sex1){
this.name=firstname;
this.Family=lastname;
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 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;
}
public void AddChild(FamilyNode Father,FamilyNode child){
//the code here
}
}
