java编程两种树形菜单结构的转换代码-创新互联

首先看看两种树形菜单结构的代码示例。

SingleTreeNode：

package com.zzj.tree;
public class SingleTreeNode {
	private int id;
	private int pId;
	private String name;
	public SingleTreeNode() {
	}
	public SingleTreeNode(int id, int pId, String name) {
		this.id = id;
		this.pId = pId;
		this.name = name;
	}
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public int getpId() {
		return pId;
	}
	public void setpId(int pId) {
		this.pId = pId;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	@Override 
	  public String toString() {
		return "SingleTreeNode [id=" + id + ", pId=" + pId + ", name=" + name + "]";
	}
}
