You will see that in order to profile your Java application with Aprof you should start JVM with -javaagent:aprof.jar option. For example, to profile well-known SwingSet2 demo you need to start it this way:

That's it! While you are using the demo, Aprof collects its memory allocation statistics and flushes it to aprof.txt file every minute.

 Aforementioned SwingSet2 demo is a complex application, hence its profiling results are not suitable for this tutorial. We will be using a series of specifically designed samples. Some of them make no sense, some are written in non-optimal way, some might even contain bugs. Most likely you will never see them in real applications. However, they help us demonstrate key features of Aprof.
