Are getters and setters poor design? Contradictory advice seen I'm currently working on a simple game in Java with several different modes. I've extended a main Game class to put the main logic within the other classes. Despite this, the main game class is still pretty hefty.  After taking a quick look at my code the majority of it was Getters and Setters (60%) compared to the rest that is truly needed for the logic of the game.  A couple of Google searches have claimed that Getters and Setters are evil, whilst others have claimed that they are necessary for good OO practice and great programs.  So what should I do? Which should it be? Should I be changing my Getters and Setters for my private variables, or should I stick with them?

Prove that if $\gcd(a,b)=1$ then $\gcd(ab,c) = \gcd(a,c) \gcd(b,c)$ An improved \rowstyle that takes the cell contents as an argument It is possible to format the column entries of a tabular in an argument-style fashion using the lrbox environment to   store the column cell in a box (say) \mybox; and supply \mybox as an argument to some other macro.   Here is a short example illustrating this fact*:  \documentclass{article} \usepackage{array}% http://ctan.org/pkg/array \begin{document} \newsavebox{\mybox} \begin{tabular}{c&gt;{\begin{lrbox}{\mybox}}c&lt;{\end{lrbox}\fbox{\usebox{\mybox}}}c}   One &amp; Two &amp; Three \\ \hline   1 &amp; 2 &amp; 3 \\   4 &amp; 5 &amp; 6 \\   7 &amp; 8 &amp; 9 \\ \hline \end{tabular} \end{document}     The above example uses the  to achieve this column-specific formatting. More specifically, each cell in the column is supplied as an argument to \fbox. Does there exist an equivalent automation that would yield    \documentclass{article} \begin{document} \begin{tabular}{ccc}   One &amp; Two &amp; Three \\ \hline   1 &amp; 2 &amp; 3 \\   \fbox{4} &amp; \fbox{5} &amp; \fbox{6} \\   7 &amp; 8 &amp; 9 \\ \hline \end{tabular} \end{document}   without having to specify \fbox for each entry in the row?  As a start, I know that the  provides \rowfont[&lt;alignment&gt;]{&lt;font specification&gt;}. However, this only applies macros &lt;font specification&gt; to each cell in a row and these macros can't take the cell contents as an argument. Moreover, you need to use the tabu environment in order to use this. So that's a little restricting. Also, trying to decipher the  macros for colouring a tabular or array row is just confusing.  The UK TeX FAQ entry on  modifies the row entries via column specifications and therefore requires the addition of "subtle" identifiers like  \begin{tabular}{|$l|^l|^l|}   to initiate $ and propagate ^ whatever row style is defined. Is there a way around this or at least a cleaner alternative that doesn't use columns to format entries in a row? In particular, a solution should provide an lrbox-style flexibility, since the contents of the cell in the to-be-styled row could be anything, even a paragraph (say).  * There are other alternatives, as indicated by the post . Few font size-related layout issues I am using a default font size of 26px and stackoverflow's layout seems to not work well with such a large sizes.  The most important issue is that many inputs tend to overflow and partially get hidden below side text. This includes one with login, ‘Title’ and — the most important issue — the editor, which makes writing posts a little painful.  Another important one is that sometimes 'search' field doesn't fit in topbar and jumps lower, being partially hidden by logo. I met that issue on stackoverflow itself only while serverfault &amp; meta display fine (but that may be related to rep or sth).  There's one minor issue too — navbar is too narrow and ‘Ask Question’ jumps below — but this one looks quite nice (maybe it's even intended?).  Screenshot: (click to enlarge) align vs equation I always use align in my documents, and avoid equation. Is there anything wrong with that? My reasoning behind this: align > equation, so why not use it? How to detect end of line with sed I'm looking for a way to only execute replacement when the last character is a newline, using sed.  For instance:  lettersAtEndOfLine   is replaced, but this is not:  lettersWithCharacterAfter&amp;   Since sed does not work well with newlines, it is not as simple as  $ sed -E "s/[a-zA-Z]*\n/replace/" file.txt   How can this be accomplished? I wonder  whether there is a function $f\colon\Bbb R\to\Bbb R$ with the folowing characteristic?   for every two real numbers $\alpha,\beta,\alpha\lt\beta$,  $$\{f(x):x\in(\alpha,\beta)\}=\Bbb R$$   I can't  say such a function does not exist, neither can I construct a example  Thanks a lot! Can you explain closures (as they relate to Python)? I've been reading a lot about closures and I think I understand them, but without clouding the picture for myself and others, I am hoping someone can explain closures as succinctly and clearly as possible.  I'm looking for a simple explanation that might help me understand where and why I would want to use them. How to download all files from Ubuntu One? I just installed Ubuntu 14.04, and Ubuntu One isn't installed by default and their download page says it comes pre installed, which doesn't help with anything.  I wanna move all my files from Ubuntu One to Dropbox, but downloading one file at a time from the browser and upload it again to dropbox will take way too long.  Is there any way to get Ubuntu One on Ubuntu 14.04? or somehow download all files from the Ubuntu One website?  I see they updated their site: How does deleting work?

Let $G$ be a group and $H$ be a subgroup of $G$ of index $2$ .Then show that if $a,b\notin H$ then $ab\in H$. I find that often after awakening from suspend on Ubuntu GNOME 16.04 with GNOME 3.20 (I have only found this issue on the latest version, though I have not tried with GNOME 3.18 on 16.04) that I get this strange font issue which can't be fixed by restarting gnome-shell and seemingly only by restarting my entire machine:            I do not believe that this is a theme issue as I have tried all the built-in themes (including the dark and light versions) and it is the same for them all. Though it does not seem to affect gnome-shell areas, that is the top-bar, the Activities Overview, etc, are not affected for some reason. So what could this issue be caused by and how can I fix or workaround it?  Information Update:  I have had a look at  but the only options in the gnome-tweak-tool for Antialiasing are Rgba, None, and Grayscale, but none of them seem to have any affect on the issue. Is there something I'm missing?
