| | [quote]just cant seem to get moduleId and module name to print out in my driver file. this is the driver file[/quote] Because, as Masijade already told you above, you have set all your variables to empty strings in that constructor and you haven't set values for them in your "driver". |
 | I can remember in college when the first visual browsers were starting to show up (Mosaic being the first). Most everything available was just text. Not long after, everyone and their dog was creating useless personal home pages with animated gifs, music, and links to crap that no one else …  |
| | Yes, to test for string equality you need to use equals() or equalsIgnoreCase(). There are more fundamental problems with what you have written there though and it will not compile. Re-examine the basic structure of 'if' statement blocks.  |
| | [quote=#1Basser;464973]I am new to java and having issues... I am using this code as an example but when I try to view it all I get is a blank screen. Can someone tell me what to write in my notepad to view the applet. I have this now <html> <head> … |
| | Well, it's difficult to speculate from a general perspective on a specific implementation such as OracleConnectionCacheImpl . Have you tried searching any Oracle forums specifically for mentions of that behavior? Are you promptly releasing connections when they are no longer needed? Is this a checked exception that you should be …  |
| | [quote=xs.gautam;465458]do u have any idea abt the cost & duration in completion of this project ?[/quote] That would depend completely on how you implement it and your own abilities to do so. |
| | Not without specific questions they couldn't. It also sounds like something more appropriate for the JSP forum.  |

| | You need a variable of type Year to hold that value in the Student class. Your constructor would also pass a Year value instead of a String. toString() can access the getGradeLevel() method of the enum value to display the string representation you have given those constants. |
| | Because all of your return statements are in conditionals (the "if"s), there is not a guaranteed return path. Instead of putting the returns in the if clauses, make a variable to hold the calculation and make a single return of that value at the end of the method. |
| | Also, instead of using the numerical values here to evaluate the dialog result[code]//This case handles the "Yes" button, when pressed. case 0:[/code] use JOptionPane.YES_OPTION and JOptionPane.NO_OPTION. Those constants are there for a reason. You wouldn't need a comment to explain [code]case JOptionPane.YES_OPTION:[/code] |
| | [quote=Triggerhappy41;462956]Now I'd like to be able to set up a scrollable GUI, but I have no idea where to start. I know JScrollPane and JScrollBar are involved, but searches on the two have come up with nothing as far as tutorials go. Does anyone have any links to a good … |
 | Well, yeah it's ridiculous - if you wave your arms and point at only part of the story out of context. When you include this part [quote] Her next-door neighbour, a city police officer who was off-duty at the time, asked her to keep it down, police said. When she … |
 | [quote=Salem;403671]Planned by bush and his cronies - not a snowball in hell's chance. Allowed to happen through incompetence and inaction of one or more previous administrations - pretty likely.

 | Perhaps he meant [url]http://uncyclopedia.org/wiki/Assburger%27s_syndrome[/url] :) |
| | I agree, marijuana should be legalized. Salem already posted most of the reasons for this and I agree with them. Alcohol is far more harmful than marijuana will ever be. |
 | [quote=lasher511;459141]None of those are actually proof that pot is causing this stupidity or evidence to support the argument that it should not be legalized.[/quote] Yep, pot smokers don't have a corner on stupid behavior. Perhaps Midi can compile a comparison list of stupid things done by people who haven't smoked … |
| | The user task bar at the top is showing an unread PM, however no unread PMs appear in any of the message lists. After a contact list invitation appeared, it showed 2 unread where it was 0 unread before, so that may have caused the discrepancy somewhere.  |
| | Re: Sum of Vectors You need to keep a vector of vectors for this. The main vector to hold a vector for each team. The team vector would hold the score of each game the team has played. Averaging these by game and team is then just a matter of nesting the inner and … |
| | Your class name needs to match the file name. You have named the class Main put placed it in midterm1.java from the looks of it. Side note: You really could use some more white space to separate your methods and logical sections within the methods. It will make it much … |
| | Re: Swing Components You want it to place them on the form or just create and return them? Having three methods that only differ in the setBounds() parameters is just unnecessary code duplication and none of those methods places anything. If you just need to create and return the three buttons, your method … |
| | Cannot find symbol means that it can't find a class,method, or variable that you have used. It could be that you misspelled something (watch capitalization, Java is case sensitive) or you are calling a method that does not exist on that class. These are very basic error messages. Look at … |
| | Well, the verification is occurring in BasicFileChooserUI.ApproveSelectionAction. If it's really worth it to you, you might be able to extend the necessary classes to provide an interruptible threaded implementation, but it might get stickier than you expect. I don't know all of your requirements, but it might be more straightforward … |
| | Collections.BinarySearch returns the index in the list where the item was found. If you need to return the object then return [ICODE]list.get(index)[/ICODE]. Your foreach loop around the search call doesn't make much sense though. For a given path, it's a single call to locate it within the list. Also, sorting … |

| | It clearly says "not a statement". You need "."s between the object reference and methods to make those valid. |
| | Re: parent/child Honestly, this is almost impossible to read and follow. Reading and following this may help a bit: [URL="http://java.sun.com/docs/codeconv/html/CodeConvTOC.doc.html"]Code Conventions for the Java(TM) Programming Language: Contents[/URL] The functioning of the methods and their names are just too non-intuitive to wade through. If you can post the relevant lines where you are … |
| | Re: odd numbers This is natural behavior for floating point numbers. They are a limited precision representation of a decimal value and you should not expect them to be an exact result. This is why they should not be used for financial calculations which require perfect precision. |

| | [quote=George87;460093]Do you have any idea from where I can get some mock exams?[/quote] Yes. One idea comes directly from Google [url]http://www.google.com/search?hl=en&sa=X&oi=spell&resnum=1&ct=result&cd=1&q=sun+java+practice+exams&spell=1[/url] A little initiative on your part would have discovered that very quickly. Professional programmers seldom have solutions directly handed to them, which is something worth pondering if you are … |
 | array[16][1][3] is of no practical use. Why nest the third level under a second level that only contains a single item? You are just making more work for yourself and creating potential problems by doing that. |
| | There are some system-specific ways to do it, but it's not really the place of System.out.println() to do that. |
