  • In Android OS or Java, what's the difference between a character sequence and a string????

    - by K-RAN
    For the API (Android SDK API version 8) functions whose definitions list character sequence parameters, I can feed the function String instead. Best part is that they work the same way, no hassle, no warnings. Is there a difference between the two types? And more importantly, is there an inherent danger if I send the function a String instead of a character sequence??? Thanks for any clarifications!!! :D

  • String replacement on a whole text file in Python 3.x?

    - by SkippyFire
    How can I replace a string with another string, within a given text file. Do I just loop through readline() and run the replacement while saving out to a new file? Or is there a better way? I'm thinking that I could read the whole thing into memory, but I'm looking for a more elegant solution... Thanks in advance

  • How to check if String value is Boolean type in Java?

    - by Ragnar
    I did a little search on this but couldn't find anything useful. The point being that if String value is either "true" or "false" the return value should be true. In every other value it should be false. I tried these: String value = "false"; System.out.println("test1: " + Boolean.parseBoolean(value)); System.out.println("test2: " + Boolean.valueOf(value)); System.out.println("test3: " + Boolean.getBoolean(value)); All functions returned false :(

  • In Java, is there a way to write a string literal without having to escape quotes?

    - by Matthew
    Say you have a String literal with a lot of quotation marks inside it. You could escape them all, but it's a pain, and difficult to read. In some languages, you can just do this: foo = '"Hello, World"'; In Java, however, '' is used for chars, so you can't use it for Strings this way. Some languages have syntax to work around this. For example, in python, you can do this: """A pretty "convenient" string""" Does Java have anything similar?

  • Module Adminhtml blocks not loading

    - by David Tay
    I was working on a Magento module and it was working fine. At some point, I was trying to enable WYSIWYG in an edit form 'content' field and suddenly, my adminhtml grid and edit blocks stopped being generated. On my system are TinyMCE and Fontis FCKEditor WYSIWYG editors extensions. I'm not sure what I did wrong but my adminhtml blocks will no longer generate. Here's a dump of all the blocks from my module's adminhtml layout: array(17) { [0]=> string(4) "root" [1]=> string(4) "head" [2]=> string(13) "head.calendar" [3]=> string(14) "global_notices" [4]=> string(6) "header" [5]=> string(4) "menu" [6]=> string(11) "breadcrumbs" [7]=> string(7) "formkey" [8]=> string(12) "js_translate" [9]=> string(4) "left" [10]=> string(7) "content" [11]=> string(8) "messages" [12]=> string(2) "js" [13]=> string(6) "footer" [14]=> string(8) "profiler" [15]=> string(15) "before_body_end" [16]=> string(7) "wysiwyg" } As you can see, the last item is "wysiwyg" but on the layout output of other magento modules, there are more blocks. For example, on MathieuF's calendar extension, these are all the layout blocks: array(26) { [0]=> string(4) "root" [1]=> string(4) "head" [2]=> string(13) "head.calendar" [3]=> string(14) "global_notices" [4]=> string(6) "header" [5]=> string(4) "menu" [6]=> string(11) "breadcrumbs" [7]=> string(7) "formkey" [8]=> string(12) "js_translate" [9]=> string(4) "left" [10]=> string(7) "content" [11]=> string(8) "messages" [12]=> string(2) "js" [13]=> string(6) "footer" [14]=> string(8) "profiler" [15]=> string(15) "before_body_end" [16]=> string(7) "wysiwyg" [17]=> string(27) "adminhtml_event.grid.child0" [18]=> string(12) "ANONYMOUS_19" [19]=> string(27) "adminhtml_event.grid.child1" [20]=> string(12) "ANONYMOUS_21" [21]=> string(27) "adminhtml_event.grid.child2" [22]=> string(20) "adminhtml_event.grid" [23]=> string(12) "ANONYMOUS_24" [24]=> string(19) "ANONYMOUS_17.child1" [25]=> string(14) "content.child0" } Does anyone have any idea what's wrong? I've already tried Alan Storm's Layout and Config Viewers and cannot find any clues as to what I did wrong. Any help would be greatly appreciated.

  • Powershell variables to string

    - by Mike Koerner
    I'm new to powershell. I'm trying to write an error handler to wrap around my script.  Part of the error handler is dumping out some variable settings.  I spent a while trying to do this and couldn't google a complete solution so I thought I'd post something. I want to display the $myinvocation variable. In powershell you can do this PS C:\> $myInvocation for my purpose I want to create a stringbuilder object and append the $myinvocation info.  I tried this $sbOut = new-object System.Text.Stringbuilder $sbOut.appendLine($myinvocation) $sbOut.ToString() This produces                                    Capacity                                MaxCapacity                                     Length                                    --------                                -----------                                     ------                                          86                                 2147483647                                         45 System.Management.Automation.InvocationInfo This is not what I wanted so I tried $sbOut.appendLine(($myinvocation|format-list *)) This produced                                    Capacity                                MaxCapacity                                     Length                                    --------                                -----------                                     ------                                         606                                 2147483647                                        305 Microsoft.PowerShell.Commands.Internal.Format.FormatStartData Microsoft.PowerShell.Commands.Internal.Format.GroupStartData Micros oft.PowerShell.Commands.Internal.Format.FormatEntryData Microsoft.PowerShell.Commands.Internal.Format.GroupEndData Microsoft.Powe rShell.Commands.Internal.Format.FormatEndData Finally I figured out how to produce what I wanted: $sbOut = new-object System.Text.Stringbuilder [void]$sbOut.appendLine(($myinvocation|out-string)) $sbOut.ToString() MyCommand        : $sbOut = new-object System.Text.Stringbuilder                                    [void]$sbOut.appendLine(($myinvocation|out-string))                                      $sbOut.ToString()                    BoundParameters  : {} UnboundArguments : {} ScriptLineNumber : 0 OffsetInLine     : 0 HistoryId        : 13 ScriptName       : Line             : PositionMessage  : InvocationName   : PipelineLength   : 2 PipelinePosition : 1 ExpectingInput   : False CommandOrigin    : Runspace Note the [void] in front of the stringbuilder variable doesn't show the Capacity,MaxCapacity of the stringbuilder object.  The pipe to out-string makes the output a string. It's not pretty but it works.

  • Find non-ascii characters from a UTF-8 string

    - by user10607
    I need to find the non-ASCII characters from a UTF-8 string. my understanding: UTF-8 is a superset of character encoding in which 0-127 are ascii characters. So if in a UTF-8 string , a characters value is Not between 0-127, then it is not a ascii character , right? Please correct me if i'm wrong here. On the above understanding i have written following code in C : Note: I'm using the Ubuntu gcc compiler to run C code utf-string is xvab c long i; char arr[] = "xvab c"; printf("length : %lu \n", sizeof(arr)); for(i=0; i<sizeof(arr); i++){ char ch = arr[i]; if (isascii(ch)) printf("Ascii character %c\n", ch); else printf("Not ascii character %c\n", ch); } Which prints the output like: length : 9 Ascii character x Not ascii character Not ascii character ? Not ascii character ? Ascii character a Ascii character b Ascii character Ascii character c Ascii character To naked eye length of xvab c seems to be 6, but in code it is coming as 9 ? Correct answer for the xvab c is 1 ...i.e it has only 1 non-ascii character , but in above output it is coming as 3 (times Not ascii character). How can i find the non-ascii character from UTF-8 string, correctly. Please guide on the subject.

  • Write problem - lossing the original data

    - by John
    Every time I write to the text file I will lose the original data, how can I read the file and enter the data in the empty line or the next line which is empty? public void writeToFile() { try { output = new Formatter(myFile); } catch(SecurityException securityException) { System.err.println("Error creating file"); System.exit(1); } catch(FileNotFoundException fileNotFoundException) { System.err.println("Error creating file"); System.exit(1); } Scanner scanner = new Scanner (System.in); String number = ""; String name = ""; System.out.println("Please enter number:"); number = scanner.next(); System.out.println("Please enter name:"); name = scanner.next(); output.format("%s,%s \r\n", number, name); output.close(); }

  • Find all substrings of a string - StringIndexOutOfBoundsException

    - by nazar_art
    I created class Word. Word has a constructor that takes a string argument and one method getSubstrings which returns a String containing all substring of word, sorted by length. For example, if the user provides the input "rum", the method returns a string that will print like this: r u m ru um rum I want to concatenate the substrings in a String, separating them with a newline ("\n"). Then return the string. Code: public class Word { String word; public Word(String word) { this.word = word; } /** * Gets all the substrings of this Word. * @return all substrings of this Word separated by newline */ public String getSubstrings() { String str = ""; int i, j; for (i = 0; i < word.length(); i++) { for (j = 0; j < word.length(); j++) { str = word.substring(i, i + j); str += "\n"; } } return str; } But it throws exception: java.lang.StringIndexOutOfBoundsException: String index out of range: -1 at java.lang.String.substring(String.java:1911) I stuck at this point. Maybe, you have other suggestions according this method signature public String getSubstrings(). How to solve this issue?

  • XSLT multiple string replacement with recursion

    - by John Terry
    I have been attempting to perform multiple (different) string replacement with recursion and I have hit a roadblock. I have sucessfully gotten the first replacement to work, but the subsequent replacements never fire. I know this has to do with the recursion and how the with-param string is passed back into the call-template. I see my error and why the next xsl:when never fires, but I just cant seem to figure out exactly how to pass the complete modified string from the first xsl:when to the second xsl:when. Any help is greatly appreciated. <xsl:template name="replace"> <xsl:param name="string" select="." /> <xsl:choose> <xsl:when test="contains($string, '&#13;&#10;')"> <xsl:value-of select="substring-before($string, '&#13;&#10;')" /> <br/> <xsl:call-template name="replace"> <xsl:with-param name="string" select="substring-after($string, '&#13;&#10;')"/> </xsl:call-template> </xsl:when> <xsl:when test="contains($string, 'TXT')"> <xsl:value-of select="substring-before($string, '&#13;TXT')" /> <xsl:call-template name="replace"> <xsl:with-param name="string" select="substring-after($string, '&#13;')" /> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:value-of select="$string"/> </xsl:otherwise> </xsl:choose> </xsl:template>
