console.readline in IntelliJ

I'm using a code Ive been working on in this project rather than the karaoke one (on the basis that using a code I've made myself will be better for my learning) when ever a console.readLine (for example :)

desiredPlayers = console.readLine("How many players are there? (maximum of 9 players): ");

is hit I get a null pointer exception and the code exits.

however this code works perfectly on the workspace what do I need to change to make it work in intelliJ

There are two ways:

First solution (used in the Treehouse-Courses I've seen where IntelliJ was used):

BufferedReader buffRd = new BufferedReader(new InputStreamReader(System.in));
String someText= buffRd.readLine();

Second solution (found with google... but didn't tried it yet):

Scanner scanner = new Scanner(System.in);
String someText = scanner.nextLine();
