Next, we want to let the user enter an SQL query, which will then be executed on the connected data source. Finally, we need to retrieve and display the results of the query. We’ll make this applet as simple as possible (for now), so that you understand the details of using the JDBC API and have a firm grasp of the foundations of making database-aware Java applets. Our next task is to fill in some of the technical details of our plan. The absolute first thing we need to do, besides setting up the constructors for the various objects we use, is design and layout the user interface.
