Expected unqualified-id before 'public'

Question

public class Main {

static Node root;
static Node current;
static boolean directionRight = false;
static boolean directionLeft = false;

}

It gives an error on line 1. I cant figure out what's the issue. Kindly help. Thanks.

Answer 1

Your declaration of public class Main should just be class Main. remove the public modifier. Also, boolean should be bool as rightly pointed by @HolyBlackCat. Right structure of your class should look like

class Main {
static Node root;
static Node current;
static bool directionRight = false;
static bool directionLeft = false;
}
