My code reads a number ("4") from a .txt file, in sd card, then It is supposed to compare this number against "5". but It is not letting me, It says  "operator '&lt;' cannot be applied to java.lang.stringbuilder"  this is how I read-    StringBuilder serverApkVersion = new StringBuilder();         try {             BufferedReader br = new BufferedReader(new FileReader(VerFileDirectory));             String line;             while ((line = br.readLine()) != null) {                 serverApkVersion.append(line);                 serverApkVersion.append('\n');             }             br.close();         } catch ( IOException e ) {             Toast.makeText(context, "error reading ver file", Toast.LENGTH_LONG).show();         }   this is how I compare-     if (serverApkVersion &gt; 5) {   PS:: I have tried this -  int serverApkVersion = Integer.parseInt(String.valueOf(serverVersion));  but it force closes, log says "invalid int "5" "
I've been using the == operator in my program to compare all my strings so far. However, I ran into a bug, changed one of them into .equals() instead, and it fixed the bug.  Is == bad? When should it and should it not be used? What's the difference?
How can a complete web page be saved and viewed on an Android device? There are situations I require to save a "complete" web page for offline reading. I can easily do that on Windows by saving the web page, but not on Android.  I am using Chrome on Android and I don't see a "save" option. Instead, I see "Save link" which, I believe, saves "only" the "pure HTML" version of a site of which the link leads to.  I have tried this but, when I view it in the HTML Viewer a lot of necessary CSS formatting and all the images were lost, which made the information misleading and incomplete respectively. (PS I thought I downloaded the complete page and the fault was that of the HTML Viewer for not rendering every thing, but I was wrong, as the desktop Chrome also displayed the "only HTML" version when I transferred those pages to my laptop through Bluetooth).  So, my question is: How can I download "a complete" web page on my Android smart-phone. It's OK if I can't view it on my smart-phone, but every thing should be in place when I view it on my laptop after transferring it. It is also OK if it is saved as a PDF file.  (PS I'm asking this as I use internet very often in my smartphone because my laptop is not connected to the internet. Also I want to transfer it to my laptop because I don't want to view those "important" pages on a small screen, it's inconvenient). Why use a z test rather than a t test with proportional data? so there are some idiosyncrasies with the method they use to invert that part of the image which I can't figure out. It could be that they just invert the luminosity but I don't know how i would do that in a dynamic way. Query to find GUID's "not in" null containing subquery returns no results How to us possessive apostrophe with words in quotes? For example,   ...a few days later I discovered that those five little boys were not that well-behaved (as I firstly thought). In fact they were quite mischievous and conniving. The broken tree next to my house and the cat with its legs tied were all their "inventions". And Lilly, as it later turned out, was able to get to Denver so fast not without those "little inventors'" help. dollar-terminated strings In my assembly language class, our first assignment was to write a program to print out a simple dollar-terminated string in DOS.  It looked something like this:  BITS 32     global _main  section .data     msg db "Hello, world!", 13, 10, ’$’  section .text _main: mov ah, 9 mov edx, msg int 21h ret   As I understand it, the $ sign serves to terminate the sting like null does in C.  But what do I do if I want to put a dollar sign in the string (like I want to print out "it costs $30")?  This seems like a simple question, but my professor didn't know the answer and I don't seem to find it using a google search. Are there rules for using manacles in combat? I can't quite find in the PHB or DMG how to slap manacles onto someone during combat. PHB 152 describes how to break out of mundane manacles, while DMG 165 shows how Dimensional Shackles work (they are essentially magic manacles -- use 1 action to bind an Incapacitated target).  Is there an official rule on how to use manacles in combat, or do we have to use house rules? Your summary page shows "N Edits to your posts" for the selected time period but you really have to be looking for it.  Could we add edits to the notification feed? You could put the reason for the edit (entered--or not--when the editor changes it) and just a link to the post. Grep: The asterisk (*) doesn't always work If I grep a document that contains the following:  ThisExampleString  ...for the expression This*String or *String, nothing is returned. However, This* returns the above line as expected.  Whether the expression is enclosed in quotes makes no difference.  I thought the asterisk indicated any number of unknown characters? Why does it only work if it's at the start of the expression? If this is intended behavior, what do I use instead of the expressions This*String and *String? Let $\mathbb R$ denote the set of all real numbers. Find all function $f: R\to \ R$ such that   $$f\left(x^2+f(y)\right)=y+(f(x))^2$$   It is the problem. I tried to it by putting many at the place of $x$ and $y$ but I can't proceed. Please somebody help me.

How to display a video in a web page using html,php How to use grep and cut together? Lets say I'm doing a database for fruits. Using a text file for it, inside contains, in this format,  (Fruit:Quantity:Cost) Apple:10:1 Orange:20:2 Pears:10:3 Banana:20:4  10 Apples at $1 each. 20 Oranges at $2 each. 10 Pears at $3 each. 20 Bananas at $4 each.   My simple script goes like this:  echo "Enter fruit to find" read fruit  echo "Enter quantity to find" read count  echo "Enter cost to find" read cost  grep $fruit FruitDB.txt     It will display the fruits in the database.  But how do i use grep and cut together to find just by the quantity or the cost. In the quantity count area, let's say i enter 20, it will display the Oranges and Banana. Or when i enter count and cost, it will display just those that meet the conditions. datetime conversion to CDT Can anyone please help me how to convert the given time into CST timezone.
