Do I have to free old objects before allocating new ones in j2me

Hi,
Do I have to free old objects before allocating new ones in j2me
sri

Usually the garbage collector does his job; but, in J2ME programming, you should not rely on this 100%, this meaning that you should call System.gc() or set object references that you don't need anymore to null. But again, this depands on the 'size' of the program you're writing.
You should check the "Edit->Preferences->Monitor" section of the Wireless Toolkit and see just how much memory your objects consume and how the garbage collector does his job.

I have to turn in my old computer before receiving new one. can I back up using time machine then restore to new computer/

I have to turn in my old computer before receiving my new one. Can I restore a backup from time machine to my new computer?

Yep.

I have replaced my old Mac Mini with new one. What should I do about my Time Capsule?

With the old Mac Mini (2009 model) I used Time Machine and a Time Capsule to back up everything on the Mac Mini itself and on external hard drive I added when I needed more storage space. I've replaced the old Mac Mini with a 2011 model, and migrated the contents of the old one to the new one from Time Machine.
I'm now trying to figure out what I should do to my Time Capsule and/or Time Machine to make backups going forward of the same content, now on my new Mac Mini and same external hard drive.
When I go into Time Machine, it does not seem to recognise the items on the external hard drive as ones that I can backup (or not, as there were some items there that I did not and do not wish to backup to Time Capsule) through the new Mac Mini.
I am uncertain too whether the Time Machine/Time Capsule will recognise the items of my old Mac Mini as the same ones that are now on my new Mac Mini and save changes there, or whether it will try to save all over again all the same items, as they are now on a different computer.
My inclination is to clear out the contents of the Time Capsule now and start all over again.
I have looked through information provided by Apple but not found answers to my questions.

The situation concerning the hard drive is complicated. It is not included in the list of Excluded Items.
If the drive is not "Excluded", then it must be included. That is the way that Apple's software works.
But, nor am I given the option to select it or any of the items in it for adding to the list of Excluded Items.
If you want to add an item to the list of Excluded items, click the + button at the bottom of the Excluded list, then navigate to select the drive to add it. Once the drive has been added, you can go back in and select the items.
When I go into the exclude from backup area and select the hard drive, it and the items in it appear in dimmed form, but I cannot select them.
Sorry, I do not understand what you are trying to say here.
What I want to do, but cannot, is what I did before, select one of the items in it not to be backed up and leave the rest to be backed up
I have no idea how you were able to do this. As long as I can remember, Time Machine will not allow you to pick and choose items on a drive to be backed up or excluded. Your option is to have the entire drive backed up, or the entire drive to not be backed up.
have not seen the 'Quick Erase' option.
You would use AirPort Utility to erase the Time Capsule drive. Open AirPort Utillty and click the Disks tab at the top of the screen. Then, click Erase Disk. The Quick Erase option will appear.

Do I need to remove old drivers before installing new ones (Windows XP)

I have an Acer Aspire 3690 laptop with Windows XP home edition installed. I've reinstalled the OS by using recovery tool, updated it again. I want to finish setting my laptop up by updating some drivers, mainly chipset and GPU. I've already found that newer ones are availabe. But do I need remove the old drivers first to avoid any problems in the future? Or do I just run the setup executable of every driver?

Run the setup and check if the new one are installed; if not remove the old drivers and install the new.

I recently brought a new HP laptop and I downloaded the newly updated iTunes on it; however I have an old Aver laptop with iTunes version 10.7 on it or the one before iTunes 11 came out. How can I transfer my movies from the old version to the new one?

I recently brought a new HP laptop and downloaded iTunes 11 on it. My old laptop which is a Acer has iTunes version 10.7, I believe. I wanted to know, How can I transfer 18 movies from the old iTunes onto my new Itunes? It only shows the most recent two movies when I look at the purchases in my account. I had a lot of moves downloaded last year from the old version and would like some assistance on how to get all those movies into my iTunes 11 library. Thank you.

you should starting with copying the iTunes folder from your old laptop to the new one.
the iTunes folder is in your user profile Music folder.
it should go to the same location on the new laptop.
Provided that you have your media, music and movies in the default location, and you sign in to your apple ID and authorize your new computer (all in iTunes)
you should have all intact.
Post if any problems.

I have copied my iTunes library onto a new computer, but when I play back the songs there seems to be random "miss" or "drop out". No probs with old computer, just the new one. I'm onto my third new computer - same problem. Any suggestions please?

I have copied my iTunes library onto a new computer, but when I play back the songs using the new computer, there seems to be random "miss" or "drop out" during play back, similar to a small scratch on a vinyl record. Although when I play the same song over again, the "miss" occurs in a different location during the song. No probs with old computer, just the new one. I'm onto my third new computer - same problem. Any suggestions please?

You don't say which version of iTunes you are using, but the symptoms you describe have been encountered by some users with the 64-bit version of iTunes 12.1.
There is an alternative version for 64-bit editions of Windows here:
iTunes 12.1 for Windows (64-bit — for older video cards)
that seems to address the most of the playback issues that some users have been reporting with the full 64-bit version of 12.1.0.77 - including problems with Bluetooth speakers where either sound is degraded or completely absent. The alternative installer here is the same architecture as most previous "64-bit" versions of iTunes, i.e., a 32-bit application with a 64-bit installer. The "for older video cards" label appears to be something of a misnomer as some people have reported that this corrects problems found on current / high-spec systems.
Some users have reported that after installing this alternative version it is necessary to adjust the "Play audio using" selection (normally to "Direct Sound" rather than "Windows Audio Session", though this may vary based on your audio hardware/drivers) in Edit > Preferences > Playback to restore glitch-free audio (one part of the reported symptoms is that the "Direct Sound" choice isn't available, usually in Windows 8). It may also be necessary to ensure that your Bluetooth speakers are active and selected as the default audio device before you run iTunes.
If this doesn't address the issue, you may want to think about reverting to iTunes 12.0 - see Turingtest2's notes on Troubleshooting issues with iTunes for Windows updates for steps needed to completely remove all installed iTunes components, and for links to the 12.0 installers.

Since this is the second computer you've had this problem with, I recommend you look for answers on the iPhone forum. My thinking is it is an iPhone issue rather than a computer issue (unless it is some software incompatibility).

In this case you won't be able to do that?

I have a mid year 2007 24 inch iMac and will be purchasing a new 27 inch Retina iMac, what is the easiest way to transfer the data and files from my old machine to the new one?

I have a mid year 2007 24 inch iMac and will be purchasing a new 27 inch Retina iMac, what is the easiest way to transfer the data and files from my old machine to the new one?

Following up on this thread,
I have a new iMac on the way and my current is from 2008, never had a problem but I am sure there are internal issues that I would prefer not to transfer.
I have no issues other then the slowness in certain programs and that is the main reason to buy a new one.
Programs like numbers and pages seem to take a longer time to open after I update to Yosemite.
I only use 272GB of 500 GB, my memory is 4GB and I am upgrading to 8Gb and bought the 4.0 processor.
Question:
Is there a way to manually transfer items or would that be a waste of time in that if there are issues they could be anywhere and would transfer anyway?

Why?
This will only create problems for you.
All iTunes pruchases are tied to the AppleID purchased with.
Just use the old AppleID. You can update it if needed.

If you are past the return date, you can sell the older iPad and put the money towards a new one.
Plus, old iPads make great gifts ! ! !

I have a new pc. If I copy the Itunes folder from my old pc onto my new one in the music folder will I be able to sync just as if it were the old one? This is from a Widows Vista machine to Windows 7.

I suspect design rather than a bug, it's too useful. The behaviour seems to have been consistent for quite a long time on both Windows and Mac machines...
Here are the typical layouts for the iTunes folders:
In the layout above right, with the media folder (everything in the red box) inside the library folder, the library will be portable. A portable library can be moved from one path to another, or even between Windows & Mac computers, without breaking the links between the library and the media, and being self-contained is much easier to backup (You do backup, don't you?). Anything that isn't stored inside the media folder must stay put or be restored to precisely the same path on a new machine or iTunes won't know where to find it. Within the media folder the relative paths from the library to the media remain unchanged and iTunes can cope even when the absolute paths are updated.
Should your library not be in the usual layout I've written some general posts on how to make a split library portable or I can give specific instructions on request.
