How to use this in Intellij instead of Jshell?

How would I make this work in IntelliJ instead of Jshell? When I run my program all I get is a test saying "Randomly picking 3 lunch spots".

public static String pickLunchSpot(String... spots){ System.out.printf("Randomly picking %d lunch spots. %n", spots.length); if (spots.length == 0){ return "Someplace with tacos"; } Random random = new Random(); // creates random selection return spots[random.nextInt(spots.length)]; // will not include the top number, will go 1 less }

public static void main(String[] args) { pickLunchSpot("Mexican Finests", "Pizza Hut", "Japanese Hibachi"); }

Try creating a new project in intelliJ, then a new class to put this code in. The code works, but the string thats returns from spots doesnt get outputted, you can System.out.println the pickLunchSpot method, since it returns a string.

Also i had to "import java.util.Random"to use the random class

yeah I cant get it to return the string even when I do this

pick.PickLunchSpots("Mexican Finests", "Pizza Hut", "Japanese Hibachi"); String places = pick.toString(); System.out.println(places);

Try this

String places = pickLunchSpots("Mexican Finests", "Pizza Hut", "Japanese Hibachi");
System.out.println(places);

The method pickLunchSpots returns a string, so you can assign it a variable then output it to console.
