public void visit(Tree tree) { System.out.print("\t" + tree.getRootData()); } } 测试: 要遍历的树如下: package datastructure.tree; import java.util.Iterator; import java.util.Scanner; public class TreeTest { /** * @param args */ public static void main(String[] args) { Tree roo...
我们定义一个tree的ADT将使用position来表达树中的节点。每个元素都在一个Position中存储。 注意position都需要遵守树结构中的parent-child关系。一个树结构中的position应该支持以下方法: 同时,树的ADT(abstract data type)应该能够支持以下接入方法使得用户可以访问树中不同节点的内容: 如果树T是有序的,那么children(...

我们利用对象引用,浅拷贝的原理,通过循环查找来组装层级,最后根据pid==null的数据一定是Tree型第一层的数据的条件进行过滤,筛选出第一层的数据组合成新的列表,达到目的。 非递归实现 //Establish tree structurestatic List<INodeDTO> buildTree (List<INodeDTO>sources){ List<INodeDTO> results =newArrayList<>()...
