12,171 Pointsconsole.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

7,160 PointsThere 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();
