 | [quote]Im not sure wht does the question want by meaning this “Each thread adds 1 to a variable sum that initially zero”…[/quote] First off; the question explicitly mentions "launching" threads which is bit different from creating a "pool" of threads. No need to extend the `Thread` class, just make your … |
 | > Is it "difficult" to do? It depends, but yes, in general I wouldn't shy from using the words "laborious" and "verbose" when it comes to wrapping native code. The process goes something along these lines: [LIST=1] [*]Create a new C or C++ project which would act as a "wrapper" … |

| | The term you should be looking for is Java RESTful framework. These frameworks basically allow you to create xml/json/XXX enabled HTTP services by mapping your output object to XML/JSON elements. There are a few frameworks which I'm aware of (but never used): * Restlet * Resteasy * Jersey The tutorial … |
 | That is because you are pretty much ignoring the exception it throws (line 28 and line 39) which is a bad thing. Never catch exceptions only to replace them with "print" statements or worst, with an empty catch block. Till you incorporate a logger in your application (which IMO every …  |
| | Hi folks, When browsing technical sub-forums, I noticed that there are a few threads which end with the OP replying "Thanks, it's solved/working now!" or something to that effect and are still not marked solved. Similar is the case with one-shot-posters who post a query which is duly answered but …  |
 | Re: Tree set problem This is actually a bug/enhancement request which was fixed in JDK 7. Previously, adding a single non-comparable element to the TreeSet didn't cause any problem but as soon as a second one was added, it caused ClassCastException because the existing object was cast to Comparable to determine the location of … |

 | Your quoting seems to be off. Try something like: [code] <script type="text/javascript"> function redirectUser() { var url = '<%= response.encodeURL("http://www.mysite/index.jsp?switch="+ intvariable) %>'; window.location.href = url; } </script> <!-- more code --> <input type="button" value="Copy" onclick="redirectUser();">[/code] |
 | IMO [ICODE]Scanner [/ICODE]is much more than just another I/O class with a pretty interface/API; it has advanced parsing capabilities which attempts to remove the utility class most programmers create to process the strings read in by a normal reader. It is pretty much capable of reading and performing complicated processing … |
 | Maybe this should be a good starting point: [code=java] // Untested import java.net.*; import java.io.*; public class A { public static void main(String args[]) { try { ServerSocket ss = new ServerSocket(); ss.bind(new InetSocketAddress(100)); System.out.println("Application started"); Thread.sleep(1000000000); } catch (SocketException e) { System.out.println("Application already running"); System.exit(1); } catch(Exception e) { …  |
| | $ is used as a separation marker for denoting inner classes. For e.g. consider the following class: [code]public class MyWidget { static class Oh { } public void doIt() { final Runnable r1 = new Runnable() { @Override public void run() { } }; final Runnable r2 = new Runnable() … |

 | [quote]And... anyone here play any good MMO like Ragnarok etc.?[/quote] I used to play Ragnarok a long time back but botters/harvesters/powerlevellers have ruined the game IMO. Plus the community isn't *that* great (I'm talking about iRO here). I started playing [URL="http://everquest2.com/free_to_play/game_overview"]EQ2 [/URL]a few months back and am finding it pretty …  |

| | Re: Connect to SQL [quote]But /how/ do I encrypt it? In PHP there's a simple md5() function, isn't there some equivalent in Java?[/quote] MD5 is not encryption but just a one-way/irreversible hashing algorithm. You have two different issues here: storing password in secure format and sending across password over the network in a secure … |

| | Assuming your palindrome logic ignores case, here is one solution: [code=java] String str = "AB , ba"; StringBuffer sb = new StringBuffer(str).reverse(); String strRev = sb.toString(); if(str.equalsIgnoreCase(strRev)) System.out.println("Palindrome"); else System.out.println("Not a Palindrome"); [/code]  |

| | Your Deck class contains a lot of compile time errors. You can't call "add" on an array in Java. Did you mean to use ArrayList class? Also, there is no reason why enums inside the Card class should be non-static since they anyways are not dependent on the instance of … |
| | There isn't much background to comment on. Sure, Java + JDBC works pretty good for accessing almost all kinds of RMDSes. Things you might want to keep in mind? To start off (assuming you are new to JDBC): 1) Use Type 4 JDBC thin driver (pure Java driver) instead of … |
| | The ideal way would be to use some sort of artifact manager like Maven or Ivy to manage your libraries. If you aren't aware of any of those and want to get started as quickly as you can, visit: [url]http://mvnrepository.com/artifact/jfree[/url] and download the latest versions of "jcommon" and "jfreechart". Put … |

| | > but I would like to know that I haven't been abandoned. Maybe because those who visit the feedback section are not too much into fancy graphs and charts? Honest question: given the kind of resource investment (programming/hardware/maintenance) this requires, what does adding this/these features buy to the site as … |
| | What JDBC driver version? Are you able to the database using a database explorer software like SQLDeveloper? Also, instead of the connection URL you are using, can you try using the one mentioned in [URL="http://java.dzone.com/articles/hibernatecfgxml-settings-derby"]this article[/URL]? |
| | Too long a question and many queries lumped together in a single post. You might want to post the minimum code required for presenting the question and add more code if requested. Plus, posting queries in code snippet as comments in a bad idea and I'm pretty sure those who … |

| | Changing a system which works for 99% of the people out there doesn't make any sense. |
| | You can, though it would require a bit of effort. Look into Webdriver/Selenium libraries for Java. |
| | I would strongly recommend you to try to simulate the programs you have written during your C days in C++. That would help you in gaining an OO perspective and make it to approach every problem in the OO way. Jumping head on in complex projects would only cause total … |

 | Re: \n vs endl [quote=jwenting;313013]no, endl should be the standard way to do things. \n is not portable, it's a throwback to C.[/quote] LF or newline is a character which belongs to the ASCII character set. Is priting out characters using streams non portable ? Cit any one situation which showcases its non portability.... |

 | A simpler approach would be to parse out an object (let's say for example PropertyInfo object) from each line in the file and then do the processing rather than parsing the file multiple times and searching for selective information. Steps: [LIST=1] [*]For each line in the file [*]Read the line … |

| | AFAIK, not possible since there is nothing which can be used to infer the type T in there. I'm assuming here that the aim is to ensure a Collection satisfies a given criteria. In that case, the simplest solution would be to create a separate method for the piece of … |
