Why is Java so hard?

I know it's a lot easier than c++, but compare to VB.NET or to C#.NET it's a nightmare.
For example, some code working under the IDE for loading images from a package directory won't work after jaring the project, since the images are jared. Why then, does it work from the IDE?
I've been trying to find a simple code example that describes how to print a screenshot without saving it to a file, and I have not succeeded, so I'll give that up in my project(just a college project, not realy important).
Many things that used to work when runing with the 1.4 jre, but not working anymore with the 1.5 jre.
I've been working hours on designing GUI with the Intellij's GUI designer and once the app is runing, teh pack() is invoked and hours of work went down the drain. Why do I need to spend hours on GUI when .net developers just put the components where they want them to be, and focus on the bussiness logic?
Apart from the challenge in beating the language (which I don't enjoy, since otherwise I would have chosen C++), is there a reason for all that?
And is it possible that someday Java will be as intuitive as VB.NET?
The basics of the language are easy to learn, but once you've passed that, it can be hell soetimes.
I have no talent in graphics or in GUI designing, and therefore I find the .net enviroment much more suitable for me.
Should I stick with Java?

IntelliJ is the best IDE I've ever used (yes, I've used Visual Studio). I can't speak to its UI designer, because I don't do Swing apps. Everything is a Web app to me these days, and UI designers take care of that in Macromedia.
Apart from the challenge in beating the language
(which I don't enjoy, since otherwise I would have

The basics of the language are easy to learn, but
once you've passed that, it can be hell soetimes.Yes, because the kinds of problems people like to solve beyond student problems are indeed hell. It's not easy in .NET, either.
I have no talent in graphics or in GUI designing, and

Why are Java files listed as needing repair in Disk Utility?

Why are Java files always listed as needing repair in Disk Utility?

FrenchToast wrote:
Baltwo, bull's eye, as always!
X423424X's question is pertinent too: you usually need to repair permissions after some major upgrade or update, not on a regular basis. Is there a particular reason why you'd often try to repair permissions? Here's more on the subject.
Repairing permissions after an update or upgrade is harmless, but I would question the need to do it even there. The Apple update itself should set the correct Permissions. I still do this, really as a hangover from Tiger days -- not certain it was really ever needed there either -- and because it's a habit that's hard to kick, but it's never found anything to repair...but for one buggy exception, which was the 10.5.8 Combo update. Running it once and then repairing Permissions created a real error. It was discovered the Combo needed to be run twice back to back and then Permissions repair. In fact, one would have been better off not running Permissions for that update to begin with. There it wasn't harnless.

BTW, even Flash updates, which always used to set incorrect Permissions, are coming in clean these days.
Exercises in Futility: Permissions Repair

Why is it so hard to do things right the first time?

My company is no longer providing Blackberry phones to its employees. So I decided to upgrade my personal phone, change my plan and try to minimize my monthly bill increase. I went with the S4, share everything with 4GB of data. I questioned the sales associate, "will this work with Good Messaging service? I have the feature number if needed." The associate said, "No it will work fine." He then asked another associate, "Right, Good Messaging will work with this share everything plan?" and the other associate confirmed. Walked out with my new phone, plan change and a $10 a month increase. When I got home I set up the Good Messaging app and work emails were available. I didn't have a good feeling about the associate having to ask again and before I decommissioned the Blackberry I wanted to triple check the Good Messaging/Enterprise data feature was part of my plan. I opened up a chat with an online associate and asked the same question... "Can you please verify the feature...?" Online associate again confirmed, "Yes, this feature is included in your plan.". I arrived at work the next day and received an email from the company support team stating that my Good Messaging service had been set up, but that my wireless plan did not appear to have the "feature" included. The email requested that I call Verizon and ask them to add the feature. I contacted Verizon immediately, informed them of the situation and conversations with other associates, the phone associate verified that I did not have the feature on my plan. She then added the feature and noted that this would increase my monthly bill by $15, asked if there was anything else, nope, and asked that I have a great day!
I'm frustrated simply because 3 Verizon employees verified that this feature was included in my plan! I'm not sure why it is so hard to do things right the first time.

Update: A couple of weeks ago I called Verizon back again after speaking with my company. The woman on the phone was very apologetic after hearing the story above. I then stated that people at my company reconfirmed that the service should be $5 not $15. She took a minute to look up the feature and said it didn't appear to be available to me for $5, but was fully aware of the feature being available for $5. She stated that she would credit my account for $10 and find out how to add the service at $5 and contact me when this was done. Finally, I felt like I got some progress.
A couple of days later I received a phone from a VZW specialist (or some other title, don't recall). The gentlemen asked about the past issues if I still had any concerns. I stated the previous person I had spoke with provided me with a $10 credit and was working on adding the feature for $5. I asked if he could confirm. He pulled up my account and stated the feature was not available to me for $5. I read him the announcement from my company regarding the "special plan" they had worked out with Verizon and he stated my account was still showing under a previous company that I had worked for. He then proceeded to say that this was probably the reason why the $5 feature was not available to me and that I should which my account to my current company. The next day I tried to switch my account to my current company and I kept getting an error message stating that I needed to contact support.
I finally got around to contacting support today and mentioned that I was trying to switch my account to my current company discount plan. I told him that I was unsuccessful trying on line. He pulled up my account and checked if my current company had a discount available. He couldn't find any discounts. While he was on the phone I went online and filled out the getdiscounts form. Got the email to my corp email and read off the discount amounts from the email. I then tried to make the changes online again and it worked. He verified the change had taken place and I asked him to confirm that the good messaging service was showing at $5. Nope it was still showing as $15. I briefly informed him of the history and asked me to hold. Came back about 30 seconds later and stated the feature is $15 for my account and there is no $5 feature.
So after 10+ years of loyal service to Verizon, I've almost completely lost all confidence in their ability to service correctly the first time.

All I want to do is upgrade two phones ... WHY IS THIS SO HARD? And, WHY CAN'T VERIZON DO THIS???!!!

In the past month, I've spoken to dozens of Verizon reps on the phone, been disconnected a few times, been at 4 different stores, been told several different things by EVERYONE, been told "oh sure, we can do that" only to be told by someone else "no we can't" ... how can you run a business like this??!!!
I AM SO FRUSTRATED RIGHT NOW I COULD SCREAM!!!!!!!!!!!!!!!!!!!!!
First, it was because our account was listed as a monthly paid cash account,
then, it was because we were trying to get phones at a franchise store,
then, it was because our account was set up as a business account (according to the Verizon rep I met at Wal-Mart, even though the Vz reps on the phone tell me it's listed as a personal account AND I sign onto our account as a personal account)
then, we were told to order our upgrades on over the phone (but then we were told we would have to pay for the phones and wait for a debit card rebate to be mailed to us, which my husband does not want to do)
then, we were told to order the upgrade phones online, but every time I try I get a processing error,
then, the computer tells us to call a specific phone number if we believe the error was not right,
then, the phone recording message repeats itself through multiple options TWICE and then hangs up on me,
then, I call another Verizon number and get a "helpful" rep who tells me we can order them on the phone ... only to come back to me after being on hold and telling me they have gone home for the day,
then, I try to get help online at Verizon.com and NO ONE IS AVAILABLE TO HELP ME.
I've been to Wal-Mart 3 or 4 times, been to the local franchise store, been to a store in the Chicago area, and have spoken with Verizon reps on the phone until I'm blue, and, still ... STILL ... I don't have new phones.
(removed) ALL I WANT IS TO UPGRADE OUR 2 PHONES ... WHY IS THIS SO HARD???!!!
We have been a Verizon customer for over 16 years, apparently that means NOTHING.

That is because the people who edit the posts are NOT CS agents but instead are people who are employed by the vendor Verizon has contracted to host the forum. I don't even believe they are Verizon employees, but employees of the Jive forum platform.
For example, if a Verizon store had an electrician repairing the lighting in one of their stores, you wouldn't necessarily walk in and expect them to get off their ladder to assist you with information about a phone since they had nothing better to do than to work on the lights. First of all, they aren't salesmen or CS agents. Second, they may not even have the capability to give you the assistance you are requesting.

Why is it so hard to migrate to Symbian?

I decided to switch from my Sony Ericson/UIQ phone to an N8 and quite honestly I have transferred most of the 500 contacts tediously over single bluetooth to messages at a time.
Before you tell me about OVI suite etc, many people may not have a PC, or may not get to install the Nokia Suite, or simply are scared or more bloating of their PC's.You should make handset to handset data portability.
I pulled out an old 6630 I had with a full address book, youre datastorer.sis file you send over does not work in older phones. UIQ rejects it (application is invalid) and so do the 2nd getn Symbian phones....
The issue is that you still don't support multi vcf support multiple VCF business cards as single messages instead of just reading the first card and stopping.
Why is it so hard? You guys at Nokia should know that people just give up, if they don't get to personalize their phone and get their data on, they just return it and go for another phone. So serious effort needs to go into this.
In comparision I got I got the (SE) VCF frile from the N8 and emailed it to myself picked up the email with my iPod/Iphone/iPad and in under a minute I had the 500 contacts in Apple devices.
Maybe instead o trying to invent augmentned reality gizmos you can focus on getting core functionality right. Maybe people will be able to switch to Symbian. If it is impossible to switch to Symbian no one will.... why not make a iPhone App for people to dump their data in a way it can be pulled into a Symbian phone.... Lots of people are sick of their iPhone and the battery shenigans.....
Make symbian an Option you can choose....

Yes but that depends you putting your data on some US based juggernaut or 3rd party that probably you may not trust with your personal data. I personally don't.
This is essential functionality that is necesary for customers to adopt Nokia products and Nokia should not be letting 3rd parties whether or how easy it is to migrate to their devices.

Why is it so hard to get Verizon to offer an alternative phone?

Hello,
I've been lurking this board for a long time, and my Fascinate has had nothing but problems.
1. The phone randomly decides to hit the back button on it's own multiple times, resulting in screencaptures. This has not been fixed for me no matter what apps I use or how many times I reset my phone. Have you ever been in a college library and tried to put your phone in standby only to hear the camera shutter noise? Everyone thinks you're creepy and that you're taking pictures of strangers. It's an embarassment.
2. Sometimes when I hit the phone icon it takes me to a black screen. Let me tell you: My cellPHONE will not let me make PHONE calls. This makes the device completely useless.
3. Sometimes I send texts to about 15 different people to confirm plans for the night, get no response at all. No texts from anybody. I wake up the next morning thinking I did something wrong and ruined relationships until I do a battery pull. Then when it starts back up it SENDS THEM THEN. Then I get a ton of confused friends wondering where I was and why they never heard back from me.
4. I have 4 different friends with the SAME EXACT ISSUES on this SAME EXACT MODEL of phone.
I am fully updated and I have never rooted this phone.
Why is it so hard for verizon to just send me a refurbished Droid X2 or Incredible 2? It can't cost that much more!
Please, if any verizon employee sees this I would love if you could help me out. The people I've spoken to on the phone only offered to send me another Fascinate. It's NOT what I need. I have been a Verizon customer for a long time and I'm thoroughly disappointed that you can't help me out by kicking me a refurb of a different model.

Hello ILikeColdPizza!
Sounds like you've gone through a great deal of trouble with your device. I would like to see if we can get your phone working the way it should.
The manufacturers warranty is a no cost option that replaces the device with the same make and model, considering the device is experiencing an electrical/mechanical defect. This is what the manufacturers cover under the standard one year warranty. When your device does not function as intended and is defective, we intern lift this up to the manufacturer to recoup our losses. This is the reason for the same model exchange policy. In the meantime, I would like to further troubleshoot your device to ensure we've resolved all the issues you're experiencing.
Have you confirmed your Fascinate is running the most recent software version? The current version would be i500.EH03, which is Gingerbread. If not, please update software. A lot of the issues you are experiencing were resolved in the latest update. If you are still experiencing issues with your device after updating the software, please let me know so I can go over other options.

Why is itunes so hard to use - and why can't apple fix it?

Why is it so hard to get iTunes to find my library?

<rant>I don't understand why it's so difficult to get iTunes to find an existing library after a move. I wish I had left this alone from the beginning. Had I known it would be this hard, I wouldn't have done this.</rant>
I have tried to move my iTunes folder from beneath my home folder to the root. After following some instructions to get this moved (I forget the link), iTunes thinks my songs are in the trash. I verified this by looking at the iTunes Library.xml file, and saw the songs linked to the songs in the trash.
So now that I've deleted my trash, all of my songs are showing up with exclamation points, saying it can't find the original song. If I locate an individual song in the new folder, it works fine. But I have thousands of songs, and have little interest in doing this for my whole library.
I've tried manually updating the iTunes Library.xml file, pointing them to the proper location, but I've figured out iTunes doesn't really use this file -- it uses the binary "iTunes Library" (with no extension) file, which I can't edit (thanks Apple).
I've also tried the option+start trick to point it to the new library (at several different points along the way), and it still thinks my songs are in the trash, I believe.
I can only assume that this has something to do with digital rights, and them not making it easy to copy music, but for us legit people, this is really a pain.
So is there a way to get this back? Or, am I left to wiping out my library, and having iTunes import my songs from scratch, and lose all of my metadata and album art?
Also once again, why is this so hard anyway? Has Apple not seen the tons of blogs and discussions on this very topic enough to warrant actually addressing this?
Thanks in advance.

Thank Chris and Diane.
After looking into this more, it looks like after transferring my media folder, I also moved my iTunes library to the root following this article:
http://www.ilounge.com/index.php/articles/comments/moving-your-itunes-library-to -a-new-hard-drive/
Somehow, something got missed (though I'm almost positive I followed that first Apple support article). Anyway, my fix was this:
1) Move my iTunes media folder back to the exact trash location it thought the songs should be in, and confirmed that the songs were once again found through iTunes.
2) Follow the Apple support article, relocated my iTunes Media folder from the trash to the desired folder in the root
3) Moved my iTunes Library back to my home folder following the iLounge article above (move physical files, then option-open iTunes and point the library to the new location).
Once I did this, everything is as I wanted it.
By the way, Chris, the reason I want my iTunes in the root of my external rather than under the Home/Shared, is because I want my songs on the external, and my Shared folder is on my internal. I want to keep all my large files on my external.
Also, Diane, what I meant by digital rights issue, I didn't mean this was the cause of my problem, but rather speculating this was the reason Apple made it so hard to relocate your media files. Again, that was just speculation, I obviously have no way of knowing. It just seems unreasonably hard to relocate your iTunes songs (or even just tell iTunes where they are after it lost them) because Apple seems to try to make users' lives easier, not harder.
Anyway, thanks again for the help.

For a communications company why is it so hard to get a phone number to talk to a real person?

Verizon is a communications company: why is it so hard to get a phone number to talk to a real person? Why when I call to set up a payment plan I get an auto response the sets up my payment date with no option to decline? Why hasn't the FCC shut this company down for breech of contract and lying to its customers?

Breach of contract? You are in breach of contract by not paying for services rendered.
Why should you be late paying an invoice and yet expect Verizon to keep your device on? You are breaching the contract.
#PMT from your device gives you an option for payment arrangements. The system more than likely can only extend the due dates by a certain number of days.
*611 or 1-800-922-0204 and ask to speak to financial services and ask them to extend the date.
Verizon would be out of business if everyone just paid them when they please.
Good Luck

Why my Toshiba mobile hard drive (1TB) can not be used in the macbook air?

Why my Toshiba mobile hard drive (1TB) can not be used in the macbook air?

If you are speaking of the USB 3.0 Canvio, you are not alone. Call Toshiba and check on their progress in alleviating the problem. I heard they are blaming Apple, but since theirs is the only drive that exhibits this problem, I think the burden is on Toshiba.
Some users have reported that by using a micro USB 2.0 connector (see bottom picture), instead of the 3.0 that comes with the drive, that it is a workaround. Notice that the 3.0 connector has sort of a "dual head" nature to the construction. One part of it is 2.0 USB micro compatible. I've never tried it myself though.

Why is Java update asking me to install openoffice?

I have installed Java jdk 1.6.
Now the update notification is asking me if I want to install openoffice.
I am not interested in that kind of notifications. (By the way I already have installed open office)
There needs to be a differentiation between java updates and other updates (3th party tools). Then I can switch off that kind of notifications.
I am only interested in Java updates.
Why is Java update asking me to install openoffice?
Thanks and regards,

It's probably asking you to update to iOS 8.2, which includes support for the upcoming Apple Watch.

Unicode String in JFrame's Title Bar / why is java a non-Unicode pgm in XP?

My big question:
Why is Java detected as a non-Unicode program by Windows XP?
I need to do the following before I can write Japanese characters on the JFrame's title bar on Window XP:
From the Control Panel -> Regional Settings and Languages -> Set the Language for non-Unicode Program to Japanese
Thanks in advance,
Noel

Hi Noel,
I'm only guessing here, but I suspect this is still the case...
Under JDK1.3, the title bar produced by a JFrame is provided by the Windows OS, rather than Java itself. You'll find that trying to display foreign characters in a JFrame's title bar on an English Windows system nigh on impossible (you're left with everyone's favourite little rectangles instead). AFAIK, Sun were looking to change this in the future, but I've no idea if they've got there yet.
Windows XP likely refers to Java as a non-Unicode program because it's looking at the main frame. Because the frame is produced by Windows itself (which last I checked was about as Unicode-compliant as my car is), it holds a different encoding to anything else within Java.
At least that's my stab in the dark. ;-)
Ta,
Martin Hughes

Why does Java have such a large footprint?

I've been curious about this topic for a while, but I haven't ever looked into this to any depth. I also posted this to stackoverflow but haven't gotten any solid responses so far:
http://stackoverflow.com/questions/1107991/why-does-java-have-such-a-large-footprint
Java - or at least Sun's Hotspot JVM - has long had a reputation for having a very large memory footprint. What exactly is it about the JVM that gives it this reputation? I'd be interested in a detailed breakdown: how much memory goes to the runtime? (The JIT? The GC/memory management? The classloader?) Anything related to "auxiliary" APIs like JNI/JVMTI? The standard libraries? (Which parts get how much?) Any other major components?
I realize that this may not be straightforward to answer without a concrete application plus VM configuration, so just to narrow things down at least somewhat: I'm primarily interested in default/typical VM configurations, and in a baseline console "Hello world" app as well as any real-world desktop or server app. (I'm suspecting that a substantial part of the JVM's footprint is largely independent of the app itself, and it is in this part that I'd like to zoom in, ideally.)
I have a couple of other closely related questions:
Other similar technology, such as .NET/mono, don't exhibit nearly the same footprint. Why is this the case?
I've read somewhere on the intarwebs that a large portion of the footprint is due simply to the size of the standard libraries. If this is the case, then why is so much of the standard libraries being loaded up front?
Are there any efforts (JSRs, whatever) to tame the memory footprint? The closest thing I've come across is a project to reduce the on-disk footprint of the JVM [1] and to modularize the standard library [2].
I'm sure that the footprint has varied over the past decade or so with every new version of Java. Are there any specific numbers/charts chronicling precisely how the JVM's footprint has changed?

Presumably versus some other VM. I would suppose the fact that much of the VM is written in java has something to do with it.

Not sure I agree with that. What size do you see with a .Net app that uses 3.0/3.5?
I've read somewhere on the intarwebs that a large portion of the footprint is due simply to the size of the standard libraries. If this is the case, then why is so much of the standard libraries being loaded up front?
Good question. There is a feature that allows multiple VMs to use the same memory footprint version of the loaded libraries. That is a new feature and it isn't clear to me if it covers the entire API. I do not know if that is dynamically built.

Why learn Java now?

I'm new to Java programming and have developed some small demo classes.
I have exp with other Visual languages and I feel like I'm taking a step back in time writing code in Notepad and compiling and running from dos etc.
I have several classes and lots of code lines to do a simple thing in swing like create a frame and a simple menu panel.
I thought Java required less code but so far it requires 3 times an much as other languages!
What visual tools or IDE�s exist for Java development other than Sun ONE Studio?
Why learn java now? The number of jobs posted online seams to be higher for Java that any other language out there like vb.net, C++ etc.
Any Comments of the Future of Java Jobs?
Running Java:
My apps run slow on XP, 384M ram.
Do production Java applications suffer from slow execution of the JVM layer?

Java code is easier to understand and more stable than "faster" languages. There is more flexibility and extensibility than in other languages, and the error-processing system is quite advanced. There are also very powerful tools you can use out-of-the-box, like JOptionPane:
import javax.swing.*;
public class Foo
    public static void main(String[] args)
        String pass = JOptionPane.showInputDialog(null, "Please enter your password");
        System.out.println("Password="+pass);
Also see javax.swing.JColorChooser.
