Java - Help solving application problem

Question

I have a class that creates objects from another class, reading the necessary data from a file. Basically, it's a thread that loads the data and adds to a queue. The data it loads is a String and an Integer per time. The problem is that the app will have 2 of those classes, so 2 threads reading from one file and addin on a queue. I'm having a lot of problems with it, so how would be the best method I could do in order to make the 2 classes add objects in the queue?

Thanks!

I think what you are referring to is the typical producer-consumer problem.

Producer/Consumer threads using a Queue should help.

You're having a synchronization issue. Do you truly need two threads? If so, put the code that adds to the queue into a synchronized block.
