为什么java中的类里面还能声明一个静态的自己

Question

如题，感觉这种情况好诡异，能不能解释一下下面这段代码的流程呢？代码如下
public class CameraInterface {
private static final String TAG = "yanzi";
private Camera mCamera;
private Camera.Parameters mParams;
private boolean isPreviewing = false;
private float mPreviwRate = -1f;
private static CameraInterface mCameraInterface;
private CameraInterface(){};
｝

可以自己调用自己啊
