So I’m having a bit of trouble setting up a basic bank account in java. I’m trying to create a transfer method that I can call to transfer funds from one account to another. The problem is that the method I have created has an unnecessary step where I have to declare the name of the object twice. To execute the transfer method, my current code requires me to write michael.acc.transfer(michael, max); if I want to transfer funds from michael to max. Any ideas on how I can simplify this a bit? For ex: michael.acc.transfer(max);

Below is the class I created with the methods that I can execute to an account.

public class Account {  static double balance; String accountId; static int nextId = 0; static final int ROUTING_NUMBER = 12345; String bankName;  {     if (ROUTING_NUMBER == 12345) {         bankName = "USA Bank";     }     else {         bankName = "Other bank";     } }  public void deposit(double amount) {     balance = balance + amount; }   public void withdraw(double amount) {     balance = balance - amount; }   public void transfer (Customer c1, Customer c2) {     double transferAmount;     int routingNumber;     {         Scanner input = new Scanner(System.in);         System.out.println("Please enter transfer amount: ");         transferAmount = input.nextDouble();          System.out.println("Please enter recipient's routing number: ");         routingNumber = input.nextInt();          if (routingNumber == ROUTING_NUMBER) {             System.out.println("Your funds will transfer instantly, you and your recipient share the same bank!");             System.out.println("Bank name: " + bankName);         } else {             System.out.println("Your funds will transfer in 2-3 business days.");         }     }     c1.customerBalance -= transferAmount;     c2.customerBalance += transferAmount;  } public static String getNextId() {     return "ACCT #" + nextId++; } 

The next class is the one I created with methods to create the customer.

public class Customer {  public String firstName; public String lastName; public Account acc; public double customerBalance = acc.balance; int defaultBalance = 100;   public Customer(String firstName, String lastName) {     this.firstName = firstName;     this.lastName = lastName;  }   public Customer() {     firstName = "John";     lastName = "Doe";  }   public void addAccount(double initialBalance) {     acc = new Account();     acc.accountId = "ACCT ID: " + Account.getNextId();     customerBalance = initialBalance;  }   public void addAccount() {     addAccount(100);  }  } 

The following are the two accounts that I created to transfer funds from one to the other.

public class Bank {  public static void main(String[] args) {      Customer max = new Customer("Max", "Doe");     max.addAccount(1500);      Customer michael = new Customer("Michael", "Smith");     michael.addAccount(3000);   } } 

I appreciate any help! Thanks 🙂
