How to use a map in java when dealing with objects

Question

So, I'm creating a program that allows users to specify the insurance cover they want as part of an insurance policy. As part of it, I need to use a map in order to track the owner of each specific insurance policy.

I have seen examples of how to use a map with regards to String and int values, but nothing for self made classes (InsurancePolicy in my case).

So, I'm trying to do it like this, but I get the illegal expression warnings:

Map<String, InsurancePolicy> coverOwnerMap<String, InsurancePolicy>();

Any help would be very appreciated.

You need to provide more information about your problem, I think, in order to get a helpful answer. For example, give specific details about the error you are getting that you don't understand (paste the error message in) or provide code snippets that don't do what you think they should. — Mike Sokolov

Right, that's invalid Java. Try,

Map<String, InsurancePolicy> coverOwnerMap = new HashMap<String, InsurancePolicy>();
