Java 遍历map

Map map = (Map) scoreList.get(j);Set scoreSet = map.entrySet();Iterator scoreIt = scoreSet.iterator();while(scoreIt.hasNext()){     Map.Entry<String, Object> entry2=(Map.Entry<String, Object>)scoreIt.next();   if(entry2.getKey().equals("firstQScore")){firstScore = (Double) entry2.getValue();infoList.add(firstScore);}else avgScore = (Double) entry2.getValue();infoList.add(avgScore);}}
