public static void main(String[] args) { List<ReplyInfo> replyInfos1 = new ArrayList<>(); ReplyInfo r1 = new ReplyInfo(); r1.setInsertTime(1544326153000L);//12-9 r1.setAlias("r1"); ReplyInfo r2 = new ReplyInfo(); r2.setInsertTime(1544585353000L);//12-12 r2.setAlias("r2"); replyInfos1.add(r1); replyInfos1.add(r2); List<ReplyInfo> replyInfos2 = new ArrayList<>(); ReplyInfo r3 = new ReplyInfo(); r3.setInsertTime(1544498953000L);//12-11 r3.setAlias("r3"); ReplyInfo r4 = new ReplyInfo(); r4.setInsertTime(1544412553000L);//12-10 r4.setAlias("r4"); ReplyInfo r5 = new ReplyInfo(); r5.setInsertTime(1544412553000L);//12-10 r5.setAlias("r5"); replyInfos2.add(r3); replyInfos2.add(r4); replyInfos2.add(r5); List<ReplyInfo> compareList = new ArrayList<>(); compareList.addAll(replyInfos1); compareList.addAll(replyInfos2); Collections.sort(compareList,new Comparator<ReplyInfo>(){ @Override public int compare(ReplyInfo arg0, ReplyInfo arg1) { int count = (int) ( arg1.getInsertTime()-arg0.getInsertTime()); if (count == 0){ return 0; } if (count > 0){ return 1; } return -1 ; }; }); for(ReplyInfo stu : compareList){ System.out.println("alias------>:"+stu.getAlias()+"insertTime------->"+stu.getInsertTime()); } }
最后 如果两个时间相同还要根据 具体内容排序 可以count= 0时继续排序
