Java 中的(T…值)流，示例
原文:https://www . geesforgeks . org/stream-oft-values-Java-examples/
流(T…值)返回一个顺序的有序流，其元素是指定的值。顺序流就像使用单核的 for 循环一样工作。另一方面，并行流利用计算机的多个内核，将所提供的任务分成许多部分，并在不同的线程中运行。
语法:
static <**T**> Stream<**T**> of(T... values)
Where, Stream is an interface and T
is the type of stream elements.
values represents the elements of the
new stream and the function
returns the new stream.
示例 1 : 字符串流。
// Java code for Stream.of()
// to get sequential ordered stream
import java.util.stream.Stream;
class GFG {
// Driver code
public static void main(String[] args)
{
// creating a stream of Strings
// and printing sequential
// ordered stream
Stream<String> stream = Stream.of("Geeks", "for", "Geeks");
stream.forEach(System.out::println);
}
}
输出:
Geeks
for
Geeks
示例 2 : 整数流。
// Java code for Stream.of()
// to get sequential ordered stream
import java.util.stream.Stream;
class GFG {
// Driver code
public static void main(String[] args)
{
// creating a stream of Integer
// and printing sequential
// ordered stream
Stream<Integer> stream = Stream.of(5, 7, 9, 12);
stream.forEach(System.out::println);
}
}
输出:
5
7
9
12
例 3 : 长基元流。
// Java code for Stream.of()
// to get sequential ordered stream
import java.util.stream.Stream;
class GFG {
// Driver code
public static void main(String[] args)
{
// creating a stream of Long
// and printing sequential
// ordered stream
Stream<Long> stream = Stream.of(4L, 8L, 12L, 16L, 20L);
stream.forEach(System.out::println);
}
}
输出:
4
8
12
16
20
