Convert IntStream to int

Question

I have never used streams in java before and am now trying to test how to accomplish simple examples with stream.

I want to return a random int int the range of 60-120 and have tried this:

return new Random().ints(1,60,121);

But I understand that I have to also convert it back to a int again but can't figure out how.

Answer 1

Since you created a Stream with a single element, you can use findFirst() to get that element:

int randInt = new Random().ints(1,60,121).findFirst().getAsInt();

That said, it doesn't make sense to create an IntStream for the sake of producing a single random number. You can use Random's nextInt() instead.

If you want to generate multiple random integers, using an IntStream would make more sense. In that case you can convert the generated IntStream to an array:

int[] randInts = new Random().ints(1000,60,121).toArray();
