LongStream range() in Java

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

Syntax :

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++) 
{
 ...
 ...
 ...
}
