Slide 12.4: Importing packages

Importing Packages

Regardless of which Oracle JDBC driver you use, include the following import statements at the beginning of your program (java.math only if needed):

 import java.sql.*;

which provides the API for accessing and processing data stored in a data source (usually a relational database) using the Java programming language.

 import java.math.*;

The package java.math.* provides classes for performing

arbitrary-precision integer arithmetic (BigInteger), which provides modular arithmetic, GCD calculation, primality testing, prime generation, bit manipulation, and a few other operations, and
arbitrary-precision decimal arithmetic (BigDecimal) suitable for currency calculations and the like.

Import the following Oracle packages when you want to access the extended functionality provided by the Oracle drivers.

   import oracle.jdbc.*;

   import oracle.sql.*;
