Vymazavanie starych poloziek - arrayList – Java – Fórum – Programujte.com

Hello world,

snazim sa z array listu vymazat objekty ktore su stare, cize ich atribut remndTime je starsi ako sucasny time

   

		//vytvorim premennu s aktualnym casom

	        Calendar c = Calendar.getInstance();

		

		//iterujem cez vsetky objekty v arrayListe

                for (Event e : Main.eventList) {

		    //tuto podmienku si nevsimajte, ta je 100% dobre	

                    if (userRelations[userNames.getSelectedIndex()].equals(e.getUserUid())) { 

	                //zistujem ci je objekt starsi

                        if (c.getTime().after(e.getRemindTime())) {

		 	    //samotne zmazanie objektu z arrayListu

                            Main.eventList.remove(e);



                        }

                    }



                }
