Stream.of() 当面对数组时除了可以使用Arrays.stream()方法外,还可以使用Stream将需要的数组转成Stream。这个方法不但支持传入数组,将数组转成Stream,也支持传入多个参数,将参数最终转成Stream Integer[]array=newInteger[]{3,4,8,16,19,27,23,99,76,232,33,96};longcount=Stream.of(array).filter(i->i>20...
for(List<String> list:lists){ for(String item:list){ newList.add(item); } } 那么使用jdk1.8提供的stream流,同时辅助of、collect和flatMap就可以直接进行转换: 代码语言:txt AI代码解释 List<String> fruitList = Arrays.asList("banana","orange","watermelon"); ...
