2. This line makes all of the IBM Toolbox for Java classes in the vaccess package available
to this program. The classes in the vaccess package have the common prefix
com.ibm.as400.vaccess. By using an import statement, the program calls the name instead
of the package plus name. For example, you can reference the AS400ExplorerPane class
by using AS400ExplorerPane, not com.ibm.as400.AS400ExplorerPane.
