LongStream rangeClosed(long startInclusive, long endInclusive) returns an LongStream from startInclusive (inclusive) to endInclusive (inclusive) by an incremental step of 1. Syntax :
static LongStream rangeClosed(long startInclusive, long endInclusive)
Parameters :
  1. LongStream : A sequence of primitive long-valued elements.
  2. startInclusive : The inclusive initial value.
  3. endInclusive : The inclusive upper bound.
Return Value : A sequential LongStream for the range of long elements. Example :
// Implementation of LongStream rangeClosed
// (long startInclusive, long endInclusive)
import java.util.*;
import java.util.stream.LongStream;
  
class GFG {
  
    // Driver code
    public static void main(String[] args)
    {
        // Creating an LongStream
        LongStream stream = LongStream.rangeClosed(-4L, 3L);
  
        // Displaying the elements in range
        // including the lower and upper bound
        stream.forEach(System.out::println);
    }
}

                    
Output:
-4
-3
-2
-1
0
1
2
3
Note : LongStream rangeClosed(long startInclusive, long endInclusive) basically works like a for loop. An equivalent sequence of increasing values can be produced sequentially as :
for (int i = startInclusive; i <= endInclusive ; i++) 
{
 ...
 ...
 ...
}
