Saving to binary/serialization java

Question

I have to, quote on quote,

1.Save accounts to a binary (serialized) file. 2.Load (recreate) accounts from a binary (serialized) file.

Answer 1

First hit on google: http://www.javacoffeebreak.com/articles/serialization/index.html - basically you should serialize your object to a file. Then you can load it into an object again later.
