java - 如何使用流API将数组划分为子数组

Question

我有一个大小为 1000 的数组。我想使用流操作来执行这样的操作:-

List list= new ArrayList();
//list is initialize to 1000 elements 

  List subList = list.subList(0, 100);
   // perform some operaions over the subarray
  List subList1 = list.subList(101, 200);
   // perform some operaions over the subarray
 .... so on
}

我想要使用流 API 的代码。提前致谢

关于:

  List<List<Integer>> result = IntStream.range(0, list.size() / 100)
         .mapToObj(index -> list.subList(index * 100, index * 100 + 100))
         .collect(Collectors.toList());
