  • Last Updated : 06 Dec, 2018

LongStream range(long startInclusive, long endExclusive) returns a sequential ordered LongStream from startInclusive (inclusive) to endExclusive (exclusive) by an incremental step of 1.

static LongStream range(long startInclusive, long endExclusive)

Parameters :

  • LongStream : A sequence of primitive long-valued elements.
  • startInclusive : The inclusive initial value.
  • endExclusive : The exclusive upper bound.

    Return Value : A sequential LongStream for the range of long elements.



    Example :




    // Implementation of LongStream range
    // (long startInclusive, long endExclusive)
    import java.util.*;
    import java.util.stream.LongStream;
      
    class GFG {
      
        // Driver code
        public static void main(String[] args)
        {
            // Creating an LongStream
            LongStream stream = LongStream.range(6L, 10L);
      
            // Displaying the elements in range
            // including the lower bound but
            // excluding the upper bound
            stream.forEach(System.out::println);
        }
    }
    Output:
    6
    7
    8
    9
    

    Note : LongStream range(long startInclusive, long endExclusive) basically works like a for loop. An equivalent sequence of increasing values can be produced sequentially as :

    for (int i = startInclusive; i < endExclusive ; i++) 
    {
     ...
     ...
     ...
    }
