Instructions

Edit the Example2 program. Follow the form of the executeUpdate() method shown above and add the required change. The Example2 program marks the location for the change with the tag <<MODIFICATION 1>>. Also, be sure that the program uses the proper URL for your database. The URL must point to the directory location for the Cloudscape database.
Modify the program to print a list of the hospital names in the database. This listing should include the new record you just added. The Example2 program contains the tag <<MODIFICATION 2>> to mark where to add these Statements. The Example2 program does not have template Statements for this second modification. You will have to copy or type in the correct Java code.
Compile the project.
Test the program and run it from the command line:
```
c:\ JDBCCourse> java Example2
```
