Hi I'm currently developing a small baking system to manage bank accounts and perform transactions such as deposit and withdraw. Also it needs to be able to create unlimited amount of accounts and delete accounts giving the account number.
I have a Client.class where I initialised all the parameters needed to create the account. I'am trying to store this class inside a HashMap as a key value, but it seems like nothing as been inserted. When I try printing out the client information I get null values
System.out.println("this has been created ");
JOptionPane.showMessageDialog(f, "Account registered successfully");
System.out.println("***********************************");
System.out.println("account registered "
+ bank.clientMap.get(userId) +" "+ bank.getLoginInfo());
System.out.println("user details " + client.getName()+" "+ client.getUsername() +" "
+ client.getAddress() +" "+ client.getBalance());
Client Account Created this has been created
account registered com.xbank.event.Client@52605789 {50.0=com.xbank.event.Client@52605789, Pass_123=com.xbank.event.Client@52605789, 115 High Road=com.xbank.event.Client@52605789, Admin=com.xbank.event.Client@52605789, user123=com.xbank.event.Client@52605789}* user details null 50.0
I don't know what I'm doing wrong, but I can't get the values inserted in the hashMap
