Stream是数据渠道，用于操作集合、数组等生成的元素序列。Stream操作的三个步骤：创建Stream中间操作终止操作一、获取stream的四种方式通过collection系列集合的stream()或parallelStream()获取。@Testvoid test11(){ List<String> list = new ArrayList<>(); Stream<String> stringStream = list.stream();}通过Arrays中的静态方法stream()获取数组流。@Testvoid test11(){ Person[] person = new Person; Arrays.stream(person);}通过Stream中的静态方法of()。@Testvoid test11(){ Stream<String> stream = Stream.of("a", "b", "c");}创建无限流/** * 迭代 */@Testvoid test11(){ Stream<Integer> integerStream = Stream.iterate(0, x -> x + 2);}/** * 生成 */@Testvoid test11(){ Stream.generate(() -> Math.random());}http://cdn.u1.huluxia.com/g4/M01/6B/2F/rBAAdl93C72AcbmKAAFeeF5qX58934.jpg
