The java.util.Arrays.stream() method returns a sequential Stream with the specified range of the specified array as its source.
Syntax
public static <T> Stream<T> stream(T[] array, int startInclusive, int endExclusive)
Here, T is the type of elements in the array.
Parameters
array |
Specify the array, assumed to be unmodified during use. |
startInclusive |

endExclusive |

Example:
In the example below, the java.util.Arrays.stream() method returns a sequential Stream 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 an Integer array Integer[] Arr = {1, 2, 3, 4, 5}; //creating Stream object by converting the //given range [2,5) of the array into stream Stream<Integer> 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:
The stream contains: 3 4 5
