In our third installment on UML we'll show you how to use sequence diagrams as a tool in your application development and an understanding of object interaction.

The UML provides two primary means to cover what's called "detailing the requirements," namely by example scenarios (shown with sequence diagrams), or by specification (captured with statecharts).

UML is used as a representation of the Java programming language. Using sample class and sequence diagrams, you can see how UML conveys unambiguous code-mapping information to developers.
