遍歷List 中 Map 的值

實現思路:

List list = new ArrayList(); Map map = new HashMap(); for(i=0;i<list.size;i++){ 　　map=list.get(i); 　　for (String key : map.keySet()){ 　　System.out.println("key:"+key+",value:"+map.get(key) ); 　　} }

項目使用:

package com.ilotterytech.bwlbis.warehouse.imports.service;
import java.io.IOException;
import java.util.List;
import java.util.Map;
