IntStream rangeClosed() in Java - GeeksforGeeks

Last Updated : 06 Dec, 2018

returns an IntStream from startInclusive (inclusive) to endInclusive (inclusive) by an incremental step of 1.

static IntStream rangeClosed(int startInclusive,   int endInclusive)

1. IntStream : A sequence of primitive int-valued elements.
2. startInclusive : The inclusive initial value.
3. endInclusive : The inclusive upper bound.

A sequential IntStream for the range of int elements.

// Implementation of IntStream rangeClosed
// (int startInclusive, int endInclusive)
import java.util.*;
import java.util.stream.IntStream;

class GFG {

    // Driver code
    public static void main(String[] args)
    {
        // Creating an IntStream
        IntStream stream = IntStream.rangeClosed(-4, 3);

        // Displaying the elements in range
        // including the lower and upper bound
        stream.forEach(System.out::println);
    }
}

IntStream rangeClosed(int startInclusive, int 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++) 
{
 ...
 ...
 ...
}
