Return object values from ArrayList

Hello -

I am just starting to learn Java and am in a bit over my head.

I have an ArrayList (clientList) with Client objects.

How to I return the clientList with the attributes of the Client objects?

I've included code for the class that handles the serialization/deserialization and the testClass I'm using to return the data.

Test Code

Code for serializing/deserializing - not done with the lookupClient code yet....not sure how to do this exactly

Thanks a ton.

Welcome to JavaRanch!

It looks like you're using JUnit, and IIRC, JUnit tests are required to have a void return value. You may want to just use a normal Java class, so your methods can return ArrayList<Client> values.

And if you are using Eclipse, get rid of those default "return null;"s
