水流(T) 返回包含单个元素的序列流,即单例序列流。顺序流的工作原理与使用单个核心的for循环类似。另一方面,并行流将提供的任务划分为多个任务,并利用计算机的多个内核在不同的线程中运行它们。
null
语法:
static <T> Stream<T> of(T t) Where, Stream is an interface and T is the type of stream elements. t is the single element and the function returns a singleton sequential stream.
例1: 单例字符串流。
// Java code for Stream.of() // to get sequential Stream // containing a single element. import java.util.stream.Stream; class GFG { // Driver code public static void main(String[] args) { // creating a stream of Strings // and printing sequential Stream // containing a single element Stream<String> stream = Stream.of( "Geeks" ); stream.forEach(System.out::println); } } |
输出:
Geeks
例2: 单例整数流。
// Java code for Stream.of() // to get sequential Stream // containing a single element. import java.util.stream.Stream; class GFG { // Driver code public static void main(String[] args) { // creating a stream of Integer // and printing sequential Stream // containing a single element Stream<Integer> stream = Stream.of( 5 ); stream.forEach(System.out::println); } } |
输出:
5
例3: 独生子女长流。
// Java code for Stream.of() // to get sequential Stream // containing a single element. import java.util.stream.Stream; class GFG { // Driver code public static void main(String[] args) { // creating a stream of Long // and printing sequential Stream // containing a single element Stream<Long> stream = Stream.of(4L); stream.forEach(System.out::println); } } |
输出:
4
