Write an expression that will cause the following code to print "less than 18" if the value of userAge is less than 18.
import java.util.Scanner;
public class AgeChecker {
public static void main (String [] args) {
int userAge;
Scanner scnr = new Scanner(System.in);
userAge = scnr.nextInt(); // Program will be tested with values: 18, 19, 20, 21.
if (/* Your solution goes here */) {
System.out.println("less than 18");
}
else {
System.out.println("18 or more");
}
}
}
