jprofiler giving unknown class name during heap profiling

Question

I am memory profiling a java application with jprofiler ,but I found instance of some unknown class(please check image link below). https://www.dropbox.com/s/jscq2x2c07x2j16/memory.png

I have class named as xyz.ServiceAppointmentPopup. but profiler is showing many instance of xyz.ServiceAppointmentPopup$1,xyz.ServiceAppointmentPopup$3, xyz.ServiceAppointmentPopup$3 etc. I couldn't find on internet what these extra instances are all about.

Does anyone know about these extra instances.?

$ means it's an inner class inside ServiceAppointmentPopup, the number means it's an anonymous inner class. In general it's a convention to name inner classes like this in the JVM ClassName$InnerClassName.
