Java8 code not resolving in IntelliJ IDEA

Question

I am using JDK - C:\Program Files (x86)\Java\jdk1.8.0_60

However, (on an earlier question I asked) a SO user gave me a Java8 solution to my problem:

int[] luckyArray = new Random().int(1, 59).distinct().limit(6).toArray();

I copied the code into my Main class and it is not resolving. Any idea why?

It's not the problem of IntelliJ IDEA, but your code.

int[] luckArray = new Random().ints(1, 59).distinct().limit(6).toArray();

See it, ints not int.

You have a mistype in your code. The red underline means that you have a syntax error. A good way to get rid of those is to hover your mouse over the error to get an explanation, then put the blinking cursor on it press alt + enter in IntelliJ IDEA to get a list of suggestions to fix the issue. If you suspect that you don't have the correct method typed, selecting the whole method (int) in your case and pressing ctrl + space will show a list of methods that you can use on that object. As you type, you will get more specific suggestions.
