Because the way you have presented your sample snippet, you would anyways be consuming a "socket" on the server … |
| | Re: Java new Object > what is the right way to create new object All the Date class constructors except the no-arg and the one which takes milliseconds are deprecated.

| | Couple of problems with your code: - Enum declarations as per the specification can't be local i.e. placed in a method. Move the enum declaration either outside of your TemperateConverter class or either outside the main() method. - Why C, c and F, f (BTW, you have got both capital … |
| | Error? I think what you have posted in the `toString()` representation of the Scanner class. If your code doesn't work, you need to add some debugging statements or even better use an IDE like Eclipse/Netbeans which has debugging support. If you are getting an exception, post the entire stack trace. … |
| | I've never used Swing/AWT but I suppose the answer to this question is pretty generic; you basically "append" the new value to the existing value rather than setting the new value as it is. So if "txtBox" is your text field, after a key is pressed, you might want to … |

 | On a related note, something which you should always keep in mind when writing code is to follow the principle of least intrusion when it comes to defining contracts; be it between methods of the same class or when exposing an external API. Let's take a trivial example of printing … |

| | As per [URL="http://mindprod.com/jgloss/javacmain.html"]this article[/URL], this feature is undocumented and deprecated. If you still want to use it, the article presents presumably correct usage of the class. If you are using Java 6+, I'd recommend using the new compiler API which doesn't tie you down to a specific implementation (i.e. Sun … |
| | Re: sqlite and java If you are open to a pure Java DB, I'd recommend [URL="http://www.h2database.com/html/performance.html"]having a look at H2[/URL]. It's faster than HSQLDB.

| | Re: dynamic loading [quote]what's thew benefits of dynamic loading in java?[/quote] DI frameworks like Spring are based around the concept of dynamically loading classes on fly and creating objects (aka beans) using them on demand or lazily. A servlet implementation like Tomcat picks up user defined class name from the web.xml file and … |

| | > I just noticed that daniweb profiles are web searchable. I wasn't expecting this Really? |
| | This happens because you don't "search" for the appropriate parent node for the new node to be inserted. You'd need a solution which recursively or within a loop searches for an appropriate parent to whose left/right the new node would be inserted. Read the basic algorithm [URL="http://cslibrary.stanford.edu/110/BinaryTrees.html"]here[/URL]. |

| | IMO implementing hybrid protocols has always been a problem. Just thinking out loud here but it seems that in your case the server has no way of knowing when the "file transfer" has completed and the user now wants to pass across a string message to the server. Also, I … |

| | Think of environment variables as OS specific variables e.g. JAVA_HOME. In windows you set them using the command [icode]set JAVA_HOME="c:/Java"[/icode], in *nix, you do it as [icode]export JAVA_HOME=/env/java[/icode]. [URL="http://en.wikipedia.org/wiki/Environment_variable"]More info here[/URL]. AFAIK, the CLASSPATH environment variable is used by your JVM process to "search" for classes. But I would rather … |
 | Re: comment box This can't be done in Javascript since its a client side technology. The only thing a Javascript code can store on client's machine is cookies which can't exceed 4KB, so I guess its out of question. You would require some sort of server side language with a database to store … |
| | Take a look at the generated source code, try to analyze it and you would know the answer to all your questions. |
| | Definitely strange that a fresh rewrite using Eclipse/Netbeans didn't work. I can't speak for Netbeans but with Eclipse how are you creating a fresh project? Are you able to run a simple "hello world" code in Eclipse? |
| | Re: java dates Use the Calendar class for performing Date related operations, esp the add() and set() methods. A sample snippet in Groovy: [code]import java.util.* def c = Calendar.getInstance() c.set(Calendar.DAY_OF_MONTH, 2) c.set(Calendar.MONTH, 2) // c now contains the date 2nd of March 2011 def i = 1 while(i <= 7) { c.add(Calendar.DAY_OF_MONTH, -1) … |
| | Re: Getting started It would be a bit difficult to diagnose the problem without having a look at the setup. Do you get the same error for a fresh java project created which contains a single Hello world code? The build file shouldn't be a problem since AFAIK it is auto-generated by Netbeans … |

| | Re: Fibonacci Series Simply put it this way, when ur applications demands a particular Fibonacci number (for eg. the 10th fibonacci number) then GOLDEN RATIO is the way to do it and if u require the whole series of numbers then the incremental method is the way.  |

| | What do you mean by "call back"? The simplest and the logical way would be to change the return type of your method to "Vector". Some other approaches would be to pass in a reference to Vector and update the Vector in your "multiply" method or have a static member … |
| | AFAIK, you'll get NULL only if you request the value of a form element which is not present in your form. If "name"/"address"/"username"/"password" are valid form fields, their value would be a blank string and not NULL in case you leave those fields blank. |
| | The simplest solution would be to use the "startsWith" method of the String class and inspect each and every dictionary entry whether it starts with the user input. But this approach can become unwieldy if the dictionary has a *lot* of entries since it means scanning the entire dictionary for … |
 | [quote]Does garbage collection occurs in PERM Area of Java Heap ?[/quote] AFAIK, yes. This aspect doesn't come into play a lot when doing regular development and using already existing libraries but becomes apparent when you implement custom classloaders and manage class loading dynamically. One e.g. would be Tomcat servlet container. … |
