先創(chuàng)建一個集合
List<String> strings=new ArrayList<>();
Collections.addAll(strings,"test","hello","huo","htt","hkk","hss");
再創(chuàng)建一個集合存儲篩選出來的數(shù)據(jù)
Liststreams=new ArrayList<>();
進(jìn)行數(shù)據(jù)篩選
strings.stream().filter(a-> a.startsWith("h")&&a.length() ==3).forEach(a->streams.add(a));
或者簡便一些
List<String> streams= strings.stream().filter(a-> a.startsWith("h")&&a.length() == 3).collect(Collectors.toList());
