Consider the following BankAccount and TestTransfer classes. What is printed when the main method of the TestTransfer class is executed?

public class BankAccount {
    private double balance;
    
    public BankAccount(double initialBalance) {
        balance = initialBalance;
    }
    
    public void transfer(double amount, BankAccount other) {
        if (amount <= balance) {
            balance -= amount;
            other.balance += amount;
        }
    }
    
    public double getBalance() {
        return balance;
    }
}

public class TestTransfer {
    public static void main(String[] args) {
        BankAccount account1 = new BankAccount(100.0);
        BankAccount account2 = new BankAccount(50.0);
        
        account1.transfer(30.0, account2);
        System.out.println(account1.getBalance() + " " + account2.getBalance());
    }
}
