i have ran predicament on system have been working on. in table "class" there multiple rows of classes. column focusing on "dates". on admin dashboard, need able list classes closest date farthest away. tried using not work way want to. mysqli_query("select * class order dates asc") my problem column "dates" serialized array of start , end dates. because of can't use strtotime() make above code work 100% correctly. my overall question is, there way can sort query serialized date string? i know opinions of different ways arise, that's not i'm shooting for. if possible or have idea, please post answer. mysql order serialized data? no, not possible. possible case when serialized data acceptable when don't need search or order through data. in other cases - store data separated fields.

in couple of places in code, i've used method set text of view instead of directly setting it. mean rather doing: edittext.settext(mystring); i've used method follows: public void settext(edittext edittext, string mystring) { edittext.settext(mystring); } (obviously looks little superfluous; used check properties of string may have impact on how set text in cases.) using method way not seem set text. why this? thanks! get id of element , set . example edittext edittext=(edittext)findviewbyid(r.id.edittext_from_example); edtitext.settext("string"); further more, if want can write seperate methods it doesnt know edittext set string.

hi have piece of java code shifts character 2, so char ch = 'a'; ch += 2; system.out.println(ch); the output in case 'c' (as expected). if rewrite code this: char ch = 'a'; ch = ch + 2; system.out.println(ch); i compilation error 'type mismatch: cannot convert int char'. why happening, aren't 2 assingments equal? it's common misconception x += y identical x = x + y . jls §15.26.2 : a compound assignment expression of form e1 op= e2 equivalent e1 = (t) ((e1) op (e2)) , t type of e1 , except e1 evaluated once. notice there implicit cast involved. when have like: ch = ch + 2; // no cast, error the type of right-hand side int while type of left-hand side char , there type mismatch between 2 sides of assignment, hence error. can fixed explicit cast: ch = (char) (ch + 2); // cast, no error
