Explaned to a friend how to use loops in java.

gistfile1.java

    public void printAccounts() {
        
        for (int i = 0; i < accounts.length; i++) {
            // schleifenlogik
            
            Account currentAccount = accounts[i];
            
            Customer owner = currentAccount.getOwner();
            
            Integer id = currentAccount.getId();
            
            double balance = currentAccount.getBalance();

        }    
    }
