what practice tells non-inherited abstract classes ? is there reason them exist in program not aiming @ providing api ? make sense systematically turn such classes non-abstract classes? if in cases ? well, abstract keyword forbids inctances creation (in order create instance 1 has inherit abstract class), however, abstract classes can have static methods e.g. // abstract: there's no sence in creating instance of class abstract class mathlibrary { // private: there's no sence in inheriting class private mathlibrary() {} // gamma function public static double gamma(double value) { ... } ... } please note, when in java abstract final class not allowed, in c# abstract sealed class static class : // c# static == abstract sealed public static class mathlibrary { // gamma function public static double gamma(double value) { ... } ... }

i'm new programming, apologize is, i'm sure, relatively simple question. i'm looking efficient way make link color within <a> tags of each html page different (i.e. 1 page have green links, while have blue links) without having add class="green" or class="blue" every single <a> tag. i understand have separate css documents each page, i'd keep whole site on 1 css page, don't have update each style sheet separately when want make overarching changes. is there way of defining style rules in <a> tags in relation class of higher tag? example, possible say <body> <div class="page1content"> <p>text here <a href="someurl.com"> link here </a> more text <a href="secondurl.com"> second link</p> </div> <div class="footer"> <p>even more text <a href="thirdurl.com"></a></p> </div> </bod...

i have following columns: - original values, b - absolute values, c - sorted absolute values (i obtain ordered values (c) using small formula given range - see link bellow) i need know each ordered absolute value, if original value or not negative: so in picture red columns filled-in manually... there way automatize via formula ? here link sandbox in excel online: http://1drv.ms/1vu2mz4 if first link not work, same thing , formulas on google sheets a partial answer, might enough if column e in screenshot want , column d helper column intended make column e easy compute. the problem abs() loses information. instead of using that, use function doesn't lose information doesn't change sort order , makes possible recover absolute value after sorting. 1 way leave positive numbers alone send negative numbers absolute value + 0.5. example, in b2 enter =if(a2 >= 0,a2, 0.5+abs(a2)) in c2 enter =small($b$2:$b$6,-1+row()) in d2 enter =int(c2...
