Use of import statements

It is common in a Java class declaration to include an import statement to access classes in another package. You can reference imported classes using unqualified class names.

For example, you can reference the Stack class of the java.util package in two ways:

• explicitly using the name java.util.Stack, or

• using the name Stack, and including the following import statement:

  import java.util.*;

Classes further up in the hierarchy must also be installed. 

A class referenced by another class, either explicitly with a fully qualified name or implicitly using an import statement, must also be installed in the database.

The import statement works as intended within compiled classes. However, within the Adaptive Server Anywhere runtime environment, no equivalent to the import statement exists. All class names used in SQL statements or stored procedures must be fully qualified. For example, to create a variable of type String, you would reference the class using the fully qualified name: java.lang.String.
