How can I determine what the type actually is?

I already posted this in "Java Programming", so I apologize if you are reading it for the second time.
I'm a CS3 student coding a data structure that uses generics. One of my methods has a possibility of much nicer results than the default if the type happens to be Character. I have been trying to figure out a way to test if the type is Character, but I can't find how to do this. Here are some things I've tried:
1. Stuff that works with variables but not types, like
if (E instanceof Character) // does not compile
if (E extends Character) // does not compile2. Something suggested by someone in "Java Programming":
if (E.class extends Character) // does not compile 3. Something along these lines:
E testOb;
if (testOb instanceof Character)The last one won't work because either I don't intialize testOb, in which case it won't compile, or I initialize it to null, in which case it will always evaluate to false anyway.
It seems there must be a way to do this. Anyone?

If your project is heavily concerned with Generics then you might want to have a look at this extremely comprehensive FAQ:
http://www.angelikalanger.com/GenericsFAQ/JavaGenericsFAQ.html
I learn best by reading technical documents from beginning to end so that's what I am doing (just about halfway through). It's nearly 500 pages in its PDF version so you may or may not want to do it my way.

When I upgraded from v4 to v5 my bookmarks was lost. I do have the one that is in the firefox toolbar. Apparently I had a bookmarks add-on. V5 changed my browser how can I determine what the program was and if the bookmarks are still there?

You CAN run 10.7, but I don't advise it, buy the 10.6.3 upgrade disk from the Apple Store online and then backup files off the machine and upgrade to 10.6.3., then Software Update to 10.6.8 would be the BEST option for your older hardware and it will run most all of your 10.5 software and be faster than 10.5 or 10.7.
If you go to 10.7 it won't run nearly any of your 10.5 software and you will have to buy all new ones for a machine that's getting a little bit dated, near it's end of life stage. 10.7 will slow your machine down, especially with low RAM.
http://roaringapps.com/apps:table
At your machines stage, the hard drive is getting old, the vents are clogged up with dust and it's going to cost a bit to get the drive etc upgraded. You can if you wish, but 10.7 really needs more RAM (4GB) and a faster hard drive.
But your still subjected to the video card going out etc.
IMO upgrade to 10.6.8 and stay there until the wheels fall off, then buy a new 10.8 machine being released after this summer or 10.9 machine.

How can I see what I'm actually video recording on iPad Air so that I don't include extra stuff at the borders of the image? It seems to automatically "zoom in" on the screen, but when I export the video, the picture isn't framed well.

When I try to record a video on the Ipad Air, the screen automatically "zooms in" closer than when I'm taking a photo. So I frame the interview and record it. But when I export it to post it or edit it, I discover that only the screen was zoomed in, the camera wasn't, so I have all this extra stuff around the edges of my frame.
I don't need to zoom in, but I do need to be able to see what I'm shooting--otherwise, as I'm videotaping, I'm guessing at my picture's framing. But every time I switch from photo to video mode, the screen "zooms in." How can I see what I'm actually recording?
I've been searching for an answer for this for a while, but I can't find any responses to it! Thanks.

How can I determine what dns server the wifi client use within airport

How can I determine what dns server the wifi client use within airport
I want to use dns servers other then the one that airport extreme is using. For example I got the 172.16.1.1 (the default gateway - airport extreme), but I want to use the office dns servers, that are in a 10.x.x.x range.
Is there a possibility?
Thanks and happy eastern

The Airport Extreme uses the DNS servers assigned by the network that it connects to. Is you Airport Extreme on the 10.x.x.x network? if it is then you are already using the 10.x.x.x DNS servers. Check your Airport Extreme with the Airport Utility and you will see in the Internet tab, the DNS servers used. The devices connecting to the Airport Extreme are assigned a DNS address of the Airport Extremes IP, In your case 172.16.1.1 but all DNS searches and resolution are done with the DNS servers you see in the Airport Extreme.
If you want to use some other DNS then you can override in the Airport Extreme which will be used by all devices connecting too the Airport Extreme, Or you can edit the DNS address in each devices wireless settings.

Yea,
I bought an original CRT iMac two day's before they were launched, which got the reseller into trouble, and had it replaced by APPLE.
This was a great learning process for me dealing with the glitches. :-)
I LOVE MAC. Now own 4 and on my 10th. in 15 years + 7 bought for family.

How can I determine what LLB a VI is being loaded from?

I've been frustrated switching between versions when an application opens and suddenly can not find a VI which is being loaded from a LLB. How can I determine what LLB (or other type of library) a VI is being loaded from ?
Is there a list of all libraries along with what VIs are included in them somewhere?
Thanks,
Dave

In the context help, enable "Show Optional Terminals and Full Path ", then just hover over your VI, either on the diagram on in the hierarchy view.

Async tcp client and server. How can I determine that the client or the server is no longer available?

Hello. I would like to write async tcp client and server. I wrote this code but a have a problem, when I call the disconnect method on client or stop method on server. I can't identify that the client or the server is no longer connected.
I thought I will get an exception if the client or the server is not available but this is not happening.

this.NewMessage.SafeInvoke(Encoding.ASCII.GetString(data));

Hi,
Have you debug these two applications? Does it go into the catch exception block when you close the client or the server?
According to my test, it will throw an exception when the client or the server is closed, just log the exception message in the catch block and then you'll get it:
private async void Process()
try
while (true)
var data = await this.Receive();
this.NewMessage.Invoke(Encoding.ASCII.GetString(data));
catch (Exception exception)
Console.WriteLine(exception.Message);
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
By the way, I don't know what the SafeInvoke method is, it may be an extension method, right? I used Invoke instead to test it.

How can I determine what computers are home sharing??

How can I determine what computers are home sharing??

Launch iTunes on the computers you're interested in. Check in the "Advanced" menu.
If "Turn on Home Sharing" is listed as an option, the iTunes library that you have open is not Home Sharing.
If "Turn off Home Sharing ([accountname]) is listed as an option, the iTunes library that you have open is Home Sharing.

Mac shut down due to problem; I rebooted fine. how do I determine what the problem was?

mac shut down due to problem; I rebooted fine. how do I determine what the problem was?

When shut down and rebooted, the Mac OS X does background maintenance on the system. That can solve minor issues.
Beyond this, it is a good idea to run Disk Repair yourself just to make sure.
Reboot with the option key held down. On the screen that comes up select the Recovery disk icon and Continue.
On the next screen Clcik Disk Utility and Continue.
In DU, in the list on the left select the drive to be repaired - click the item that is indented to the right, not an an item whose name starts on the far left.
Click First Aid, then Repair Disk.
After that is done, quit DU and restart as usual.

How can I determine what computers are authorized on my iTunes account?

How can I determine what computers have been authorized on my iTunes account? I've reached my limit and now I'd like to deauthorize one computer.
Thanks,

There is no list.
You can only deauthorize a single computer from that computer.
If you do not have access to the computers, then you would have to deauthorize all.

How can I determine what is using my broadband?

I have limited broadband (not uncapped) but something is chewing up my available data at an alarming rate. How can I determine what it is and how to stop it?

You should be able to click on the one item, and then
select Info, to see what else is involved w/ this kernel.
And check the Console utility, to see what (among so
many) specific items may relate to the use of internet.
Items by Time & Date narrow the field somewhat.
Good luck & happy computing!
