Path path=Paths.get("data.txt");try(Stream<String>stream=Files.lines(path)){// 使用 stream 处理数据}catch(IOException e){e.printStackTrace();} 通过生成器创建:除了从现有的数据源创建 Stream,我们还可以使用生成器来生成元素。Java 8 中提供了Stream.generate()方法和Stream.iterate()方法来创建无限 ...

去重List<String> newList = Stream.concat(stream1, stream2).distinct().collect(Collectors.toList());// limit：限制从流中获得前n个数据List<Integer> collect = Stream.iterate(1, x -> x + 2).limit(10).collect(Collectors.toList());// skip：跳过前n个数据List<Integer> collect2 = Stream....
String[] array={"a","b"}; Stream<String> stream = Arrays.stream(array); 1. 2. 2.3、使用Stream的静态方法:of()、iterate()、generate() int[] array={1,2,3,4}; //public static<T> Stream<T> of(T... values) Stream<String> stream = Stream.of(array); ...

Exercise? What is a correct syntax to create an Iterator object named it for a cars collection? Iterator<String> it = cars.iterator(); Iterate<String> it = cars.iterate(); Iteration<String> it = cars.iteration(); It<String> it = cars.it();Submit Answer »...
iterate方法,其返回的也是一个无限长度的Stream,与generate方法不同的是,其是通过函数f迭代对给指定的元素种子而产生无限连续有序Stream,其中包含的元素可以认为是:seed,f(seed),f(f(seed))无限循环。 -iterate(Tseed,UnaryOperator<T>f) 1 示例: Stream.iterate(1, item -> item +1).limit(10).forEach(...
