Who wants to give their opinion?

I�m new to Java GUI development/design and I desire some insight from some more experienced minds.
I�m designing a solution for a school project that is to contain a main GUI window and 2 GUI dialog windows that pop up after certain events. My question is: should I create 3 separate classes (1 for the main GUI, and 2 for each dialog), or should I just create 1 class to handle building and displaying all 3 GUI objects.
I suppose if I created 1 class I could just create separate methods for building each dialog when the time came� However I�m leaning towards creating 3 separate classes for some modularity�
Thoughts?

Since you're just looking for opinions, I'd have to say that I agree with the last poster (3 separate classes). More classes with appropriate names will make the code easier to maintain and understand. I know it's just for a school project, but good, clean, maintainable code is a very good practice to get into.

  • For anyone who wants to customize their IT Superhero...

    You are persistent!!

    i took the IT Superhero quiz, and it made me a girl! so i tried retaking it until i got what i wanted, and finally, i just decided to reverse engineer their logic answers! it ended up being (somewhat) simple, and yet tricky to decipher, and so i decided to share my findings here at the Water Cooler to anyone in a similar predicament as me :Di highly recommend taking the quiz FIRST to see what you get (it IS rather fun), but once that is out of the way, feel free to have fun (i know i did). and don't forget to use your avatar if you like it!so basically, you just take the address of the Superhero quiz:

  • A SOLUTION for those who want to organise their TV SHOWS properly!

    Hi folks;
    I posted this in "Using iTunes for Windows" as well.
    Finally found a simple, and yes, EASY way to get your self-burned TV shows (from your DVD collection) into iTunes WITH the proper info(ie: season, show, title, description, network, etc...)
    A simple program called "TV TAGGER".
    Basically, it's a GUI for Atomic Parsley so you don't have to learn another language to do this stuff. It's got all the spaces for you to fill in the show info you want.
    It only works for TV SHOWS though...
    Here's the link:
    http://69.117.40.60:3000/atomicgui/
    Basically, all you have to do is open TVTagger, go to 'file' and open all the episodes for the show you want to classify and fill in the blanks for each episode. Once you're done, either hit 'apply' under 'tab' OR, (to make it faster), hit 'apply all' under 'file'. It will make a new copy of the TV Show in the same folder as the original with a slightly different title (adds some stuff). Delete the original and you've got TV Shows with the proper tags.
    Then open iTunes, remove all the TV Shows from it (NOT deleting the original files) and re-open the TV Shows. This time, the shows will be classified in the TV SHOWS tab and will show the season and all that jazz.
    I know, it sounds bigger than I meant it to, but it's really easy...
    Good luck!

    you could ask your school for premissions to see

  • When one or more family members who have been sharing one iTunes account wants to create their own iTunes account can they each upload the music/apps from the shared iTunes on their devices to the new iTunes account?

    When one or more family members who have been sharing one iTunes account wants to create their own iTunes account can they each upload the music/apps from the shared iTunes on their devices to the new iTunes account? 

    Yes. I would clarify your statement about the "shared" iTunes Library though. If you want each iOS device to have its own music library, you should create separate user accounts for them. Read:

    It sounds like you are talking about the cloning tool?
    Tool looks like this:
    Then when selected you can change the size of the brush and using Alt (windows) and Command (Mac) to select your region you want to copy then start to create you cloned image.
    Hope this helps?

  • I am about to upgrade my ipod. i want to give my old ipod nano to a friend. what do i need to do so they can use it on their computer?

    i am about to upgrade my ipod and want to give my old ipod nano to a friend. what do i need to do so thay can use it on their computer and create their own itunes account?

    Connect it to iTunes, select the Nano in the "devices" column and click "Restore". The warning window you get will ask you if this is what you really want to do.
    Your very lucky friend will essentially have it in the same condition as if she bought it new.
    One more thing: if you registered it in My Support Profile, make sure to un-register it. Only you can do that. Have your friend register it under her own Apple ID.

  • How come Verizon Wireless will not give their customers a corporate number, email, or address to send complaints?

    I have been with Verizon Wireless for 7 years and I have went through more problems in customer service in the last year then I have in my whole 7 years. Usually if I have a problem they fix it immediately, I tend to call instead of going into a Verizon store because Verizon stores just do not care about their customers. I am beginning to think the same thing about Verizon Wireless customer service.
    Problem number 1: Verizon Wireless making changes to my account, aka payment arrangements, without my knowledge or consent. Making my phone shut off because I was 3 days late. Yes THREE DAYS... not months. Then after they turned my phone on because of their error I paid my bill. About a couple weeks later I decide that I want to purchase a new phone and want it billed to my account. They then tell me that no I could not have it billed to my account because my phone was shut off for non-payment. I then explained that it was an error, they then told me that they could not over-ride the system and I would have to wait 6 months to bill to my account. I asked if that meant I could bill to my account even if Iam late a couple days or what. They told me as long as my phone had not shut off because of non-payment I would be able to bill to my account, also that they would write a formal complaint on the person who made a payment arrangement on my account without my consent and they would get back to me. That was in Mar of 2013. I am still waiting for a reply from my complaint.
    Problem number 2: In March of 2013 Verizon had an email option on their website where you could email corporate and they will email you back. Since then they have taken it off and will not give their customers email, number, or address where they can reach corporate at.
    Problem number 3: Sept of 2013, it has been 6 months. I I then call Verizon to bill to my account a new phone, because I wanted to start a new contract. Well they tell me that because I do not pay on the same day of every month I will not be able to bill to my account and they can not over ride the system. I then tell them that this was not what was told to me in March of this year. The rep tells me that she cant do anything for me except investigate it and get back to me within 4 hours. I say okay and leave my number I wanted to be reached at, I asked if she was sure that she was going to call me back because I have been told in the past by verizon wireless reps that I would receive calls from them and they never bothered to return my call, because basically I was un-important. She stated that she would and she appreciated the business I gave Verizon for the past 7 years. (she was a supervisor by the name of Jeniffer in customer service on the east coast). 5 hours later I still had not received a call so I call back and ask to speak to a supervisor they then tell me that my claim was denied for "unknown" reasons about the call 6 months ago and they were not going to let me bill to my account and they couldnt help me further. I asked for a a corporate number, email, or address and they told me repeatedly that they did not know them and could not give them out if they did know them. That if I had a complaint he could notate it and make sure it was handled. Psssh just like it was handled 6 months ago. I daid thank you but no thanks and ended my call soon thereafter.
    It just galls me that Verizon treats their customers who make them money by using their services and phones every year. They do not have any care for the complaints and actions of their workers as well as their customers.
    I just want to know it anyone knows they corporate number, email or address??
    Or maybe a verizon rep out there (which I pretty much doubt will respond to my question)
    If I dont receive an answer soon I believe... no i KNOW I will be taking my $127.33 else where and maybe just maybe I can get better customer service, even if its just a tiny inch better than Verizons.
    AT&T here I come.

    yesterday i went to verizon with a 8 day old broken phone after 40 mins in line to be helped  the sales staff at glenway av in cincinnati turned me around and sent me out the door without solving my problem or returning my less than 14 day old phone.  i called corporate at >>removed<< they called the store and made an appointment with the manager to resolve my issue. when i returned to the store i was told i had to wait in line again so i decided to get loud enough for every customer in the store to hear what kind of customer service i was recieving.  so then the employee at the door not the manager called the police on me and threw me out of the store so today i am returning my phones and am seeking other service providers  but anyhow the corporate number i provided is a good one and the people you reach will solve your problem  corporate level is does do a grat job but the customer service level and store level employees i have found to be very unproffessional and extreemly mismanaged.

  • I just purchased 2 new iPhones for my wife and I and set them up. We want to give the old phones to our kids, with the ability to share all the songs in my iTunes account. How do I want to give new names so our old phones sync with our kids names?

    Sorry for the long intro question.  I just bought a new iPhone 5S for me and a new 5C for my wife.
    We want to give our kids my old 4S and my wife's old 4.  We backed up our old phones and restored
    our info to our new ones, but when we connect our old phones, they still show all our songs and iTunes
    settings on them (along with the same names as our new ones).
    We want to set up our old iPhones for our kids to be able to have their own names on theirs so that
    when we connect to my iTunes computer, it sees each phone accordingly, and has only the songs
    that they select (whereas I want to keep ALL my songs in my iTunes account on mine, not just some).
    How do I do this?

    You are most welcome
    Each post should have the text "this helped me" or "this solved my question," or something similar. Just click on whichever one applies to that particular post!
    This tutorial has more info.

    Hello everyone!i got a problem about this used ipad2 that i had bought  from a friend of my friend.the problem is i cannot activate it i asked my friend to contact the previous owner..according to my friend the previous owner had already removed the device from his account..but still it keeps on asking me to enter the email and password..what should i do now?maybe the previous owner didn't want to give me his Email add ppassword for his own personal reason..please help me this ipad has been in here since April 2014..thank you

    The person who sold you the device can remove the ID without giving it to you. Follow the steos in "What to do if you no longer have the device." In the artcle below. If you can't find the person or they won't do it you're stuck with a unusable device.

  • This is for people who wants to mirror all they apple devices when they travel.

    this is for people who wants to mirror all they apple devices when they travel and don't want to unplug everything from the apple tv and take it with them, you can get the amazon fire tv stick and download an app called airplay upnp or the reflector app and mirror all of your apple devices to it, it is great for traveling easy to setup and move around, for example if your traveling and want to use it in the conference room and then want to take with you back to the hotel for the night and plug it in and keep on doing that routine.
    it will be great to use hopeful until apple comes out apple with their own apple tv stick 

    The Verizon DVR is admittedly not the sharpest box on the market. I admit to giving up on the multi-room DVR product, it just never worked satisfactorily for me.
    Hopefully features/functions issues  will improve in the near term with the Cisco/Scientific Atlanta box that obviously isn't going to make Q1. I admit I have ceased  holding my breath. Something does have to happen fairly soon because 160gb drives are literally going out of production.
    You do however make two statements that incorrect. Current TiVO's only need 1 cable card, since the standard cable card today in Verizon's stock  is the M-Card. You also have the option with TiVO of paying either an annual fee, or a one time fee, both of which are lower in the long term than the month to month fee. Alternatively you can by the Moxi DVR, and it includes lifetime service in the purchase price.
    While in theory a truck roll costs $79, in practice if it is for a Cable Card install, it is free (I think  FCC regulations preclude the charge).
    Apparently there is nothing in Verizon's order processing system that tells reps that there is no charge for Cable Card installations, so they often quote the $79 fee because that is the standard charge for technician to come out. As far as I can tell (and there have been lots of posts about cable card installs), no one has in fact been charged the $79 fee..

  • Who wants to help 100 students create something amazing at CeBIT?

    Dear SAP Mentors.
    This year at CeBIT, Ann Rosenberg and SAP University Alliances want to showcase their commitment to transform the perception of SAP towards students and are organizing an InnoJam for university students.
    The event will be held in parallel to CeBIT on March 6/7 in a media school close to the exhibition grounds, with the winner(s) presenting their results on the big stage in the SAP area at CeBIT.
    We will use Design Thinking, just like we did for the pre-TechEd InnoJams.
    Students will come from universities in the DACH region, plus Poland (CeBIT focus country 2013) and Russia.
    The theme is addressing the CeBIT theme of "shareconomy" and the SAP CeBIT theme "true dreams". We are thinking along the lines of "fair and sustainable solutions for a better future in our connected digital society of the 21st century". We got in contact with Betterplace (http://www.betterplace.org) and concrete topics are likely going to focus on social responsibility, the work of NGOs, etc.
    More infos here: http://wiki.sdn.sap.com/wiki/display/events/SAP+InnoJam+at+CeBit+2013
    In order to give students an exceptional experience, we are looking for as much expert support as possible. These students are most likely unfamiliar with SAP technologies. DT coaches are also needed (Hester Hilbrecht from TIP DevEx is coordinating that). In general, I think that having people there mentoring these young minds during the event would be a great addition to the event. If you are interested to contribute to that experience or if you are travelling to CeBIT anyways, we would be delighted to add you to our list of attendees.

    I hope I can count on you!
