public abstract class SimpleApplication

```
SimpleApplication is the base class for all jME3 Applications. SimpleApplication will display a statistics view using the StatsAppState AppState. It will display the current frames-per-second value on-screen in addition to the statistics. Several keys have special functionality in SimpleApplication:

Esc - Close the application

C - Display the camera position and rotation in the console.

M - Display memory usage in the console.

A FlyCamAppState is by default attached as well and can be removed by calling stateManager.detach( stateManager.getState(FlyCamAppState.class) );

```
public void initialize()
```
    Description copied from class: LegacyApplication
    
    Do not call manually. Callback from ContextListener.
    Initializes the Application, by creating a display and default camera. If display settings are not specified, a default 640x480 display is created. Default values are used for the camera; perspective projection with 45° field of view, with near and far values 1 and 1000 units respectively.
    
    Specified by:
    
    initialize in interface SystemListener
    
    Overrides:
