I'm going to ask a question based on the question I asked earlier. As an answer to my question, he/she wrote different customers and others one by one and directed them to classes such as customer1HomePage, customer2HomePage, but in my assignment, I need to add at least 30 different customers and it is not possible to open separate home classes for each. Can I write this customer, employee and management information in a normal main class (customer customer1 = new customer(Jane,25663)..and until customer customer30 = new customer(John, 163637) and direct it to customer employee and management home pages? and add customer cs as a constructor in login and get these names as cs.getName, why do I get getName is null point result when I do that? so instead of typing usename.equals(12345) what I want from you is a different solution. please post the solution using java and please give example with code

JAVA

I will ask you to create a login and register page using only JAVA SWING GUI. It will be a classic bank login page, and it will be possible to enter the system in three types as employee and management. and you need to create 4 different customers, 3 customers and 2 nd management from each of them using only Java. when their different passwords and user names are entered, they must enter their own system. Another thing is the register page is directed to the login page after each user registered, and then they open their own home page. JAVA URGENT
