Java中的LongStream of()
LongStream of(long t)
LongStream of(long t)返回包含单个元素的顺序 LongStream。
句法 :
static LongStream of(long t)
参数 :
- LongStream :原始长值元素的序列。
- t :表示 LongStream 中的单个元素。
返回值: LongStream of(long t) 返回包含单个指定元素的顺序 LongStream。
例子 :
// Java code for LongStream of(long t)
// to get a sequential LongStream
// containing a single element.
import java.util.*;
import java.util.stream.LongStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an LongStream having single element only
LongStream stream = LongStream.of(-7L);
// Displaying the LongStream having single element
stream.forEach(System.out::println);
}
}
输出:
-7
LongStream of(long… values)
LongStream of(long... values)返回一个顺序有序的流,其元素是指定的值。
句法 :
static LongStream of(long... values)
参数 :
- LongStream :原始长值元素的序列。
- values :表示新流的元素。
返回值: LongStream of(long… values) 返回一个顺序有序的流,其元素是指定的值。
示例 1:
// Java code for LongStream of(long... values)
// to get a sequential ordered stream whose
// elements are the specified values.
import java.util.*;
import java.util.stream.LongStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an LongStream
LongStream stream = LongStream.of(-7L, -9L, -11L);
// Displaying the sequential ordered stream
stream.forEach(System.out::println);
}
}
输出:
-7
-9
-11
示例 2:
// Java code for LongStream of(long... values)
// to get a sequential ordered stream whose
// elements are the specified values.
import java.util.*;
import java.util.stream.LongStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an LongStream
LongStream stream = LongStream.of(-7L, -9L, -11L);
// Storing the count of elements in LongStream
long total = stream.count();
// Displaying the count of elements
System.out.println(total);
}
}
输出:
