Reader Questions

• Question: Can you suggest any good books to expand into basic Java/database interactions with either Oracle or Microsoft SQL? Also, would this be done with JDBC?
  Answer: Java software can access relational databases with either Java Database Connectivity (JDBC) or the JDBC-ODBC Bridge. The same techniques are required in either case -- your Java class loads a database driver and uses it to connect to the database and make queries.
  Sams Teach Yourself Java 2 in 21 Days, Fourth Edition, a more advanced book I coauthored with Laura Lemay, devotes a chapter to JDBC and JDBC-ODBC.
  Since you mentioned Oracle, you ought to take a look at Oracle and Java Development by Bulusu Lakshman, also offered by Sams Publishing.

Activities

• Solution 1: IdFiles.java and IdFiles.class. Before running this application, put one or more MP3 files in the same folder. All of them will be renamed using the ID3 information in the each file, if it exists.
• Solution 2: This exercise is facetious, but if you'd like to buy the album, The Colour and the Shape by the Foo Fighters is sold on Amazon.com.
• Solution 3: ReadJava.java and ReadJava.class.
