Cannot find symbol for *class name*? Java

Question

Both classes are in the same package so I'm very confused as to why it isn't working. It does work in netbeans however I am using Visual Studio Code now. I will include the code and the error I get.

Division Class (containing main method)

package project;

import java.util.ArrayList;
import java.util.Scanner;


public class Division
{
    public static Scanner scanner = new Scanner(System.in);

    public static void main(String[] args)
    {


        ArrayList<Fighter> fighters = new ArrayList();

        fighters.add(new Fighter("Conor McGregor", 29, "Ireland", 21, 3));
        fighters.add(new Fighter("Gunnar Nelson", 28, "Iceland", 16, 3));
        fighters.add(new Fighter("Stipe Miocic", 33, "USA", 17, 2));
        fighters.add(new Fighter("Cody Garbrandt", 26, "USA", 11, 0));
        fighters.add(new Fighter("Demetrious Johnson", 30, "USA", 27, 2));
        fighters.add(new Fighter("Jose Aldo", 31, "Brazil", 26, 3));
        fighters.add(new Fighter("George St Pierre", 40, "Canada", 25, 2));
        fighters.add(new Fighter("Fabricio Werdum", 40, "Brazil", 22, 7));
        fighters.add(new Fighter("Michael Bisping", 39, "United Kingdom", 30, 7));


        displayAllFighters(fighters);


    }

    //Adds fighter to ArrayList
    public static void addFighter(ArrayList<Fighter> fighters)
    {
        System.out.print("Please enter fighters name: \t");
        String name = scanner.nextLine();

        System.out.print("\nPlease enter fighters age: \t");
        int age = scanner.nextInt();

        scanner.nextLine();

        System.out.print("\nPlease enter fighters country: \t");
        String country = scanner.nextLine();

        System.out.print("\nPlease enter amount of wins: \t");
        int wins = scanner.nextInt();

        System.out.print("\nPlease enter amount of losses: \t");
        int losses = scanner.nextInt();

        fighters.add(new Fighter(name, age, country, wins, losses));

        System.out.println("Fighter Added!");
    }

    //Removes a fighter from ArrayList
    public static void removeFighter(ArrayList<Fighter> fighters)
    {
        System.out.print("Please enter the name of the fighter you wish to remove: \t");
        String name = scanner.nextLine();

        for (Fighter fighter : fighters)
        {
            if (fighter.getName() == name)
            {
                fighters.remove(fighter);
            }
        }
    }

    //Display info of all fighters
    public static void displayAllFighters(ArrayList<Fighter> fighters)
    {
        for (Fighter fighter : fighters)
        {
            System.out.println(fighter);
            System.out.println("==========================================");
        }
    }

    //Counts amount of fighters with a win % that is less that entered value
    public static int countWinPercentLowerThan(ArrayList<Fighter> fighters , int value)
    {
        int count = 0;

        for (Fighter fighter : fighters)
        {
            if (fighter.getPercent() < value)
            {
                count++;
            }
        }
        return count;
    }

    //Counts amount of fighters with a win % that is greater that entered value
    public static int countWinPercentGreaterThan(ArrayList<Fighter> fighters , int value)
    {
        int count = 0;

        for (Fighter fighter : fighters)
        {
            if (fighter.getPercent() > value)
            {
                count++;
            }
        }
        return count;
    }

}

Fighter Class (which can't be recognized when compiled)

package project;

    }

    public Fighter(String name)
    {

        this.age = 0;
        this.country = "TBA";
        this.wins = 0;

    }

    public String getName()

    public double getPercent()
    {
        int totalFights = this.wins + this.losses;
        double percent = this.wins * 100/totalFights;

Answer 1

The first mistake I see is that the constructor is has weight class parameter required but when you initialize the arraylist with Fighter class, it is missing that value.

eg. fighters.add( new Fighter("Conor McGregor", 29, "Ireland", 21, 3 )); is missing weight class.
