Java code Cannot find symbol problem

Question

I'm triing to compile three classes they are in the same directory yet it still says Cannot find symbol I can't find any thing in the spelling...
file #1
package banking;
import java.util.*;
public class Bank {
     private ArrayList<Account> accounts = new ArrayList<Account>();
     private int numOfCust;
     public void addCustomer(String fName, String lName){
          numOfCust += 1;
          accounts.add(Customer(fName, lName));
     public int getNumOfCustomers(){
          return numOfCust;
     public Account getCustomer(int custNum){
          return accounts.get(custNum);
}Next Class used in above:
package banking;
public class Account {
     private double balance;
     public Account(double init_balance){
          balance = init_balance;
     public double getBalance(){
          return balance;
     public boolean deposit(double amount){
          if (amount < 0)
               return false;
          else
               balance += amount;
               return true;
     public boolean withdraw(double amount){
          if (balance < amount)
               return false;
          else
               balance -= amount;
               return true;
}The last class:
package banking;
public class Customer {
     private String firstName;
     private String lastName;
     private Account account;
     public Customer(String fName, String lName){
          firstName = fName;
          lastName = lName;
     public String getFirstName(){
          return firstName;
     public String getLastName(){
          return lastName;
     public Account getAccount(){
          return account;
     public Account setAccount(Account acct){
          account = acct;
          return account;
}
