二、代码分析

package com.test.test;

import java.util.Iterator;

import net.sf.json.JSONObject;

public class TTTT {
	public static void main(String[] args) {
			JSONObject bandwidth = new JSONObject();
			JSONObject data = new JSONObject();
			data.put("in", "88");
			data.put("out", "99");
			bandwidth.put("vnic00375", data);
			bandwidth.put("vnic00376", data);
			bandwidth.put("vnic00377", data);
			Iterator it = bandwidth.keys();  
			JSONObject bandwidth2 = new JSONObject();
			 int i=1;
			while(it.hasNext()) {  
				 String key = (String) it.next();  
				 String value = bandwidth.getString(key);  
				 key="内网网卡"+i;
				 bandwidth2.put(key, value);
				 i++;
			}
			System.out.println(bandwidth2);
	}
