The java.util.Arrays.stream() method returns a sequential DoubleStream with the specified range of the specified array as its source.
Syntax
public static DoubleStream stream(double[] array,
int startInclusive,
int endExclusive)
Parameters
array |
Specify the array, assumed to be unmodified during use. |
startInclusive |
Specify the first index to cover, inclusive. |
endExclusive |
Specify index immediately past the last index to cover. |
Return Value
Returns a DoubleStream for the array range.
Exception
Throws ArrayIndexOutOfBoundsException, if startInclusive is negative, endExclusive is less than startInclusive, or endExclusive is greater than the array size.
Example:
In the example below, the java.util.Arrays.stream() method returns a sequential DoubleStream with the specified range of the given array as its source.
import java.util.*;
import java.util.stream.*;
public class MyClass {
public static void main(String[] args) {
//creating a double array
double Arr[] = {1, 2, 3, 4, 5};
//creating DoubleStream object by converting the
//given range [2,5) of the array into stream
DoubleStream stream = Arrays.stream(Arr, 2, 5);
//printing the stream
System.out.print("The stream contains: ");
stream.forEach(str -> System.out.print(str + " "));
}
}
The output of the above code will be:
