Dflip240 :
Im having a little issue figuring out how to use stream to generate an infinite sized, sequential stream which contains all the numbers in a fibonacci sequence.
How would I be able to print out an infinite stream? Any advice helps, thanks.
JB Nizet :
public class Fibonacci {
public static void main(String[] args) {
IntStream stream = IntStream.generate(new FibonacciSupplier());
stream.limit(20).forEach(System.out::println);
}
private static class FibonacciSupplier implements IntSupplier {
int current = 1;
int previous = 0;
@Override
public int getAsInt() {
int result = current;
current = previous + current;
previous = result;
return result;
}
}
}
Note however that this stream can't be infinite as soon as you reach the 47th element, the value is too large to fit into a positive integer.
