In this video, you learn how to use the UML features of the IDE to create a simple UML class diagram. You then use the code generation and reverse engineering features to develop a simple banking application, which you can test by executing a test class. This banking application is greatly simplified; a real model for an application of this type would require more detail. The purpose of this tutorial is to introduce some of the IDE's UML features, not to teach you about UML concepts or the Java programming language..
