Java DoubleStream of()

DoubleStream of(double t)

DoubleStream of(double t) 返回一个包含单个元素的连续的DoubleStream。
语法

static DoubleStream of(double t)

参数

DoubleStream : 一个原始双值元素的序列。
t：代表DoubleStream中的单个元素。

返回值： DoubleStream of(double t)返回一个包含指定单一元素的连续DoubleStream。

例子:

// Java code for DoubleStream of(double t)
// to get a sequential DoubleStream
// containing a single element.
import java.util.*;
import java.util.stream.DoubleStream;
  
class GFG {
  
    // Driver code
    public static void main(String[] args)
    {
        // Creating a DoubleStream having single
        // element only
        DoubleStream stream = DoubleStream.of(8.2);
  
        // Displaying the DoubleStream having 
        // single element
        stream.forEach(System.out::println);
    }
}

输出:

8.2

DoubleStream of(double…values)

DoubleStream of(double…values) 返回一个连续的有序流，其元素是指定的值。
语法:

static DoubleStream of(double... values)

参数

DoubleStream : 一个原始双值元素的序列。
values : 代表新流的元素。

返回值： DoubleStream of(double…values)返回一个连续的有序流，其元素是指定的值。

例子 1 :

// Java code for DoubleStream of(double... values)
// to get a sequential ordered stream whose
// elements are the specified values.
import java.util.*;
import java.util.stream.DoubleStream;
  
class GFG {
  
    // Driver code
    public static void main(String[] args)
    {
        // Creating an DoubleStream
        DoubleStream stream = DoubleStream.of(8.2, 5.6, 4.1);
  
        // Displaying the sequential ordered stream
        stream.forEach(System.out::println);
    }
}

输出:

8.2
5.6
4.1

例2 :

// Java code for DoubleStream of(double... values)
// to get a sequential ordered stream whose
// elements are the specified values.
import java.util.*;
import java.util.stream.DoubleStream;
  
class GFG {
  
    // Driver code
    public static void main(String[] args)
    {
        // Creating an DoubleStream
        DoubleStream stream = DoubleStream.of(5.2, 4.2, 6.3);
  
        // Storing the count of elements in DoubleStream
        long total = stream.count();
  
        // Displaying the count of elements
        System.out.println(total);
    }
}

输出:
