 | No, at least not when using the standard library because in *nix, the creation time isn't stored anywhere. If you are running on a windows box, you have two options: - spawn a shell process which fires the command 'dir /a' and extract the creation time [easiest] - Use JNI, … |

| | Re: Split a line? One of the important things you should know as a Java developer is to find the classes in the standard library which contain the functionality you desire. As an example, since you need to operate on Strings and need to generate a char array, looking into the documentation of [ICODE]String … |

 | Tsk tsk, let's not get into unproductive discussion here. I am pretty sure you both understand that there is no point in nitpicking each others' post to the point that it turns into name calling. |

| | Terms like efficiency make little sense when used in an absolute context. For finding the most efficient way to solve a problem you first need to track down your applications' usage pattern i.e. what kind of file reading does your application need? Is the data read promptly consumed or is … |

| | Re: File IO Since a 2D char array is nothing but an array of char arrays, you can convert the char array to a String using [ICODE]String.valueOf()[/ICODE] and write it out to a file using [ICODE]PrintWriter[/ICODE]. When reading in data, just read in lines of data and recreate your 2d char array using … |

| | Re: Merging 2 Arrays [QUOTE=jobojo;744856]I was wondering if someone could explain to me how to merge two arrays so that one is not simply appended to the other, but they need to be merged into one sorted array. I could simply append the two arrays and then sort the result, but that would be … |
| | Some points: • You need to tell us a bit more than the normal "this doesn't work" thing. What do you mean when you are not able to generate unique numbers? Is the array not filled completely or the numbers are getting repeated. • You need to break out of … |

| | Vector and hence Stack are legacy/by default thread safe classes. Consider using ArrayList and LinkedList in lieu of the above mentioned classes. And as for your problem, replace:[code] Vector<String> temp= new Vector<String>(); temp =vVariables; variables.push(temp);[/code] with[code] variables.push(new Vector<String>(vVariables));[/code] In your code, you create a new Vector instance referenced by `temp' … |
 | No l33t speak and use of code tags on the very first post; this has given me happiness indeed. Anyways, the problem with your approach is that you attempt to read in `int' from the file but don't test for it i.e. instead of [ICODE]fileRead.hasNext()[/ICODE] test for [ICODE]fileRead.hasNextInt()[/ICODE]. Also, your … |
| | *Not working* is not a very helpful description of the problem. You should try debugging your script and inspecting variables to see if they are causing a problem. Use the Microsoft Script Debugger if using IE and Firebug if using Firefox. Also, onclick works: [code] <!DOCTYPE html PUBLIC "-//W3C//DTD HTML … |

| | Use a Firefox addon, Firebug, to debug your Javascript applications. Move the semicolon separated statements in the onclick handler of the INPUT element to a separate function for easier debugging. |
| | Like it has been already suggested, keep pushing the items in a Set until the size of the set is 25 [since you are attempting to fill a 5 x 5 array]. Since a Set rejects duplicate elements, the only time the size of a Set will be 25 is …  |
