3. Reversing Array Using Stream API In this approach, we will use read the array elements in reverse starting from last position, and then we will store all the elements in a new array. The original array remains unchanged in this approach. final String[] arr = new String[]{"A","B"...
是的，请使用IntStream执行此操作：
4. 代码示例 importjava.util.List;importjava.util.stream.Collectors;importjava.util.Collections;publicclassMain{publicstaticvoidmain(String[]args){// 步骤1:创建一个List对象List<Integer>numbers=List.of(1,2,3,4,5);// 步骤2:使用stream()方法获取流List<Integer>reversedNumbers=numbers.stream()// ...
// create a simple Stream of strings Stream<String> stream = Stream.of("Alex", "John", "Baray", "Emma"); // reverse stream and print elements stream.collect(Collectors.toCollection(LinkedList::new)) .descendingIterator().forEachRemaining(System.out::println); In the above example, we ...
