Abstract
One of the advantages of designing an object-oriented system is that you can re-use existing classes. If these classes have been fully tested you can use them to build new applications without re-testing them. Since this approach reduces the amount of new untested code, applications can be created quickly and are likely to have fewer errors. Java 2 has an extensive class library, many Java classes are available from other companies, and of course you can create your own classes to help you build complex applications quickly with the minimum of errors.
