title: java sql query on data imported from csv file
body: <p>I am planning a Java program which is working with data in csv files which I will load into 2D arrays or a hash map or some other object.  I am curious if Java has any library or anything that would permit the implementation of SQL statements to query subsets from internally stored data objects.</p>
  
  <p>I am wondering if maybe the JBDC drivers that allow Java to connect with or control relational SQL databases can be applied to internal data objects.</p>
