intelliJ get classname of variable at carret

Hi,

anyone knows how to get the classname of a variable under the mouse caret ? 

I started something like that

final PsiFile file = CommonDataKeys.PSI_FILE.getData(dataContext);
Project project = CommonDataKeys.PROJECT.getData(dataContext);
PsiElement elementAt = file.getViewProvider().findElementAt(editor.getCaretModel().getOffset(), JavaLanguage.INSTANCE);

i guess there is some whay of getting the classname of my elementAt ?

code ex

public class OneClass{
private static final MyObject ONE_CONSTANT = ....


private Object createToolbar() {
    Object appGroup = new MyClass(ONE_CONSTANT[caretIsOnThisWord]);
    ....
}
}

So i don't want the method to tell me OneClass (this I managed to do :P )
but I want the method to tell me that I'm on a MyObject element
