Hints

A static field is shared by all objects of the class.

nextId++ uses the value, then increments it.

Solution explanation

Static fields belong to the class itself, not to each object.

Show solution

import java.util.Scanner;

class Ticket {
    static int nextId = 1;
    final int id;
    final String name;

    Ticket(String name) {
        this.id = nextId++;
        this.name = name;
    }

    @Override
    public String toString() {
        return "#" + id + " " + name;
    }
}

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        Ticket.nextId = 1;
        int n = sc.nextInt();
        for (int i = 0; i < n; i++) {
            System.out.println(new Ticket(sc.next()));
        }
        System.out.println(Ticket.nextId - 1);
    }
}
