使用Java中的TCP套接字编程来验证帐号

Question

I am kind of new to socket programming.That being said,I am not new to jAVA.I got a question.I need to write a program where I can use a client to provide an account number so that the server can retrieve information using that account number (of a bank). My question: Can I put a few accounts in a hashmap or something and write a method inside the server to only fetch my account (if provided in the hashmap).In other words,no code needed.I will write that myself.Only trying to find an approach?

Answer 1

It sounds like Remote Method Invocation (RMI) would suit your needs. HashMap implements Serializable , so you would be able to send it directly to the server.
