Reading custom classes from files in java

In my java class, one thing that we are often asked to do is to read in lines from a file that contain different data types (example String productName, double price, int quantity, etc) and perform tasks with these objects. So for the example above we'd been working with the class Product(String productName, double price, int quantity). The only way that I have been able to do this is by storing them all in different ArrayLists, which seems very inefficient. Can anyone provide some insight into a better way of doing this?

Why not create class Product and make it java.io.Serializable. In doing so, you can easily serialize the object to a file as well as de-serialize from a file to the object.
