Java 代码优化：使用迭代器提高效率

public static List getMidLevelEvaluationsForStream(final List midLevelDemocracyEvaluationVOS) { final ListIterator listIterator = midLevelDemocracyEvaluationVOS.listIterator(); MidLevelDemocracyEvaluationVO previous = null; while (listIterator.hasNext()) { MidLevelDemocracyEvaluationVO current = listIterator.next(); if (previous != null) { setInfo(previous, current, 'T00008'); } previous = current; } return midLevelDemocracyEvaluationVOS; }
