Updated section on deleting files. This section now includes Java code that will create a file so the last block of Java code has something to delete. The Python example provided will not run because the os library cannot be imported. I was unable to test the Java code within the book.

-            Finally, we will take a look at using Java to delete files. This one is pretty straight-forward and follows the structure used to create files. This time, however, try/catch blocks are not needed for the program to compile. We will call this class DeleteFile. The completed code should look something like this.

+            The next example is Python code that can be used to delete files. This code cannot be run because importing <c>os</c> is not possible with the technologies used to write this book:
+        </p>
+
+        <program xml:id="delete-file-java" language="python">
+            import os
+            file_name = "myfile.txt"

+                try:

+        </program>
+
+        <p>
+            And finally, we have Java code that deletes files. We will call this class DeleteFile:
+        </p>

         <program xml:id="delete-file-java" interactive="activecode" language="java">
