Naming java objects

So right now, I am making a simple java banking program. It allows you to add a customer and deposit/withdraw funds. Right now, I have 3 classes: Main, Bank, and Customer. Right now I have it so that when you add a customer, it asks you for a name. But right now I am having trouble naming them. I want Customer to have a username as the object name. For example, if I typed in Bob1789 as the username, the program would do: 

Customer Bob1789  = new Customer("Bob1789");

If I typed in randomcustomer123 the program would do:

Customer randomcustomer123 = new Customer("randomcustomer123");

So basically, whatever I type in the box from the scanner, to be passed to the Customer name. 

Customer (whatever was typed in the scanner) = new Customer((whatever was typed in the scanner));

I have tried to do this, but java always assumes that the scanner.NextLine() is the Object name.

Is there any way to do this?

Don't know why you want to use obj name. Probably you need to use HashMap<String, Customer> where name is the key and value is the object.

Map<String, Customer> map = new HashMap<>();

to add map.put("yourName", obj); to fetch map.pget("yourName");

You can use a HashMap<String, Customer> for this. This allows you to store name-customer pairs.

HashMap<String, Customer> allCustomers = new HashMap<>();

To create a new customer and put it into the map,

String customerName = scanner.nextLine();
allCustomers.put(customerName, new Customer(customerName));

To get a customer with a specific name, use this:

allCustomers.get("some name");
