13Novice Examples
14</h2></div></div></div><p>
15The Geant4 toolkit includes several fully coded examples which
16demonstrate the implementation of the user classes required to
17build a customized simulation. Seven "novice" examples are provided
18ranging from the simulation of a non-interacting particle and a
19trivial detector, to the simulation of electromagnetic and hadronic
20physics processes in a complex detector. Each example may be used
21as a base from which more detailed applications can be developed. A
22set of "extended" examples implement simulations of actual high
23energy physics detectors and require some libraries in addition to
24those of Geant4. The "advanced" examples cover cases useful to the
25developement of the Geant4 toolkit itself.
26</p><p>
27The examples can be compiled and run without modification. Most
28of them can be run both in interactive and batch mode using the
29input macro files (<code class="literal">*.in</code>) and reference output files
30(<code class="literal">*.out</code>) provided. These examples are run routinely as
31part of the validation, or testing, of official releases of the Geant4
32toolkit.
