Can you listen to System.out ?

Good morning form. Is there a way to listen to System.out?
This could be useful in testing. You could compile a test version of the app and report all Sys out activity then turn it of in production (or not). The point would be to be able to apply this to applications after they were written. (as in not a consideration at the time the app was written).
I know if the app is run from a command line you can pipe the output to a file.
Thanks

STHi, you should use logging instead. E.g. Log4J or java.util.logging

    How can you listen to music without headphones?

    - Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so.
    Try the following to rule out a software problem
    - Reset the iPod. Nothing will be lost
    Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Reset all settings
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup
    - Restore to factory settings/new iPod.
    - Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack.
    Apple Retail Store - Genius Bar
    Apple will exchange your iPod for a refurbished one for this price. They do not fix yours.
    Apple - iPod Repair price
    A third-party place like the following will replace the jack for less. Google for more.

    I'm not aware of any, not to say that there aren't any issues.
    it may have nothing to do with ntpd, there are a lot of things running.
    ntpd just happen to make the log entry at the same time as the panic.
    I would check to see if there are any updates available for you system.
    if this is the first time that this has happened. it may be (pick one):
    cosmic rays
    sun spots
    the trilateral commission
    if this happens more frequently and that traces look the same, then
    there may be a real problem that needs to be looked into further.

  • Hi, We are a physiotherapy practice trying to use i-cal as a clinic diary systaem for 15 therapists. We need to block out availability of therapists but cant do this? How can you block someones diary out for specific times on i-cal? Any help please..

    Hi, We are a physiotherapy practice trying to use i-cal as a clinic diary system for 15 therapists. We need to block out availability of therapists but cant do this? How can you block someones diary out for specific times on i-cal? Any help please..

    iCal is designed for personal use, and isn't really meant to handle this sort of situation.
    The best suggestion I can offer, though it's a trifle untidy, is: create a calendar for each therapist, giving each a different colour. Enter the availability for each therapist - if it's on a weekly basis you can make them repeating events. Then add the individual appointments, which will show alongside in the daily view. In this example, the 'purple' therapist is available from 1030 to 1700 and has appointments at 1200 and 1500.
    If you have more than a few therapists available at any one time it's liable to look a bit messy, but it's the best I can think of at the moment.

    My iPod touch is disabled after too many attempts and I want to enable it without getting it clear so can you please help me out in this....

    A data recovery company MAY be able to do it for a price. The Disabled is a very good security feature.
    JWhy not just restore from the last backup you have?
    Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.

    If recovery mode does not work try DFU mode.

    For how to restore:
    iTunes: Restoring iOS software
    To restore from backup see:
    iOS: How to back up     
    If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
    You can redownload most iTunes purchases by:

    Take the memory card out of the camer and put it in a card reader.  When it mounts on the desktop select it and try to change the name.  However, that might make it incompatible with the camera.  You'll just have to try and see.

  • How can you listen to music and play a game at the same time?

    How can you listen to music and play a game at the same time?
    I am playing music, by starting the Crash Baandicoot Nitro Kart 3D game it shuts off the music playing. Is there a way around this?
    It seems like this should be possible.

    Select the music play list you want to listen to and start it playing. Go back to the home screen and start the app you want to use, music will stop. Press the home button two time quickly and it will bring up a simple control for controling the music. This works for me with all of the apps I have purchased including games. Just a note you can pull up the same music control if the iPod is a sleep and locked by pressing the button three times quickly.

  • HT204387 can you listen to music with your ipod touch 4g and a bluetooth handsfree device

  • Can you buy a slide out keyboard case for the six plus? Like you can for the 6.

    can you buy a slide out keyboard case for the 6 plus?

    There are 2 separate issues here:
    - The Apple 30 pin to USB cable was redesigned to remove the 2 button squeeze feature pricesley because of your issue with the buttons falling off and consumers being unable to disconnect the cords.  The newly redesigned cable removes these 2 side buttons for a shorter 30 pin connector that will work just fine in Apple devices.  If there is an ergonomic reason for wanting the larger 2 button design you can buy a host of 3rd party Apple 30 pin to USB cables on the market.  http://store.apple.com/us/product/MA591G/C/apple-30-pin-to-usb-cable?fnode=3a

    - The issue of your iPad reporting that it isn't charging is a DIFFERENT issue.  Your USB cable is FINE.  The reason you are getting this message is beacuse the Power Adaptor that the USB cable plugs into isn't providing enough electrical juice.  If you are plugging your USB cable into your PC it might not be getting enough power.  If you are plugging it into your iPhone Power Adaptor (5W) it isn't strong enough to charge your iPad with it on (it will trickle charge if you have your iPad off).  What you need is the Apple 12W charger for iPad.  Your original power adapter that came with you iPad 2 was a 10W charger that Apple no longer sells.  Make sure the USB cable you are using it plugged into either a 10W or 12W power adapter!  http://store.apple.com/us/browse/home/shop_ipad/ipad_accessories/power
    Tech speak if interested: the 12W charger uses the USB cable to detect which iPad is connected and gives it 1 AMP for iPhone, 2.1 AMP for iPad 1,2 & Mini and 2.4 AMP for iPad 3&4.

    Can you listen to music on the iPod Classic without the headphones?

    The Classic does not have an internal speaker, so either you need to:
    plug in headphones
    connect the iPod to an amplifier and speakers (from the headphone socket)
    connect it to an iPod Dock cable and plug that into an amplifier
    Place the iPod into the Dock on something that has a Dock connector and amplifier built in.

    How can you redo initial system setup macbook pro?

    Like when Setup Assistant fires up and lets you migrate? In general, that would imply having to do a complete reinstall. And I've always been under the impression that when you do that, the reinstall software does not contain all the extra goodies that come with a new from-factory install (such as iLife).
    But as Prof. Kappy wants to know, the specifics are very version dependent.
