ABSTRACT
So far in this book we have been very happy to use the collections libraries without fully understanding how they work. That is fine for much of what we have done and in a first year of CS study, but real developers need to have knowledge of what is really happening so that they can make informed decisions about what collection types to use in different situations. This chapter will begin to reveal how we can build our own structures for storing data by linking objects that store small pieces of data together.
