android - new to java - Class<?> does not accept generic classes -


i created following method:

public  void getclasses (  set<class<?>>param ) { }

in main, created following :

set<pupilvo> hold = new treeset<pupilvo>(); getclasses(hold);  <-- gives error

the error is: 

the method `getclasses(set<class<?>>)` in type test1 not applicable arguments (`set<test1>`)

test1 name of class doing code in ...

here pupilvo class looks like.

if limited understanding correct, set<class<?>> means can pass in set of kind of class wish... if true, why error?

you're having issue because method getclasses expects set of class objects, in code you're passing set of pupilvo objects

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
