how can you make a void method that transfer money from one account to the other on java

To create a void method in Java that transfers money from one account to another, you will need to follow these steps:

1. Define the method signature, including the return type (void), the name of the method (e.g. "transferMoney"), and any parameters that the method will need (e.g. the source and destination accounts, and the amount of money to be transferred).

2. Inside the method, use the appropriate methods or setters on the source and destination accounts to adjust their balances according to the transfer. For example, you could call the "withdraw" method on the source account and the "deposit" method on the destination account to complete the transfer.

Here's an example of what this might look like:

public void transferMoney(Account source, Account destination, double amount) {
  source.withdraw(amount);
  destination.deposit(amount);
}

Keep in mind that this is just a rough outline of the steps involved, and you will need to consider things like error handling, security, and other factors when designing and implementing a real-world money transfer system.
