How do i clear the console

Hi Experts
I need to know "how do i clear the console " and
"how do position the mouse cursor in x and y coorditates in a console "
Thanks in advance

You don't. Or, it depends on the console. Depending on your point of view.
Java doesn't directly control it the same way that it controls an AWT window for example. It just sends bytes to it. If the console is capable of interpreting bytes in such a way to clear the screen, then it can.
Most consoles a person is likely to use will interpret VT100 commands. Look them up; try google. You can just output those commands and the console will do what they say, hopefully.
Sending a control-L (bye 0x0c, I think) may do it. Try that.
Or you can try the java curses library.
All this may be wrong if you mean something by "console" other than what I think you mean.

How do I clear the screen in text mode (cls)

How do I clear the screen in text mode (cls)
Thanks,

Clearing of console is an OS specific command, so
in case of Windows you should try:
Runtime.getRuntime().exec("cls");Though it wouldn't help, because exec() will be done as a separate
process... :)

I have forgotten my password and locked my phone, how can i clear the problem

By coincidence, this happened to my son just last night. You do NOT have to restore it to a new phone, but you probably want a current backup.
Luckily, you can still sync and back it up even if it's locked, so connect it to the computer you usually sync it to. Go to the summary page. It's easiest and fastest to use a local backup, so if iCloud backup is on, turn it off and click "Backup now".
After it backs up, either click "Restore iPhone", or
- hold home and the top button until the screen goes black, release the top and continue to hold the home button until iTunes says "iPhone in recovery mode detected".
Follow instructions to restore from backup, and then sync to restore content. Your phone will come up in an unlocked state. If you have any stuff that was purchased directly to the iPhone (only), you'll have to re-download it.
Remember to turn iCloud backups back on if you use them.
If you don't sync you iPhone to a computer then I *think* those instructions with the buttons will put it into a mode where you can restore it from the cloud (make sure it is NOT connected to a computer while you do this). Otherwise, you will have to restore it as a new phone, then go to settings, reset, then restore it from the cloud.

How do I clear the downloads folder?

How do I clear the downloads folder? I swear there used to be an option for this when I right clicked on the downloads folder that is on my bottom bar but I don't see one now. This is making me crazy.
Also, when I click on the bottom bar Downloads folder to display the items in the Downloads folder, I've selected it to be arranged as a fan and by the date added. I've downloaded two copies of the same item and did this back to back because I didn't see the first download in the folder once I'd downloaded it. I don't see the first of the two downloads unless I open the whole folder in its own window. Shouldn't I see them both at the bottom of the list since they are the two most recent downloads? I'd accidentally downloaded duplicate copies previously and it had displayed them in this manner.
Please help!

The best way to delete is just open them in finder. Mark them all and delete.
In the fan, you can select the sort order by right click (cntl click) the download folder and choosing "sort by" date added.

Captfred

How do I clear the cache in my MacBook Pro 10.9 Maverick

How do I clear the cache in my MacBook Pro 10.9 Maverick operating system? Can anyone provide step-by-step instructions. I'm a big dummy when it comes to this sort of thing.

Hey DrSteveMc,
Thanks for the question. The following resource outlines where the cache folder is stored. Note that the Library folder is hidden by default in OS X Mavericks. To access this folder, hold down option when clicking the Go menu in Finder:
OS X Mavericks: What is the Library folder?
http://support.apple.com/kb/PH14330
Mac OS X: How to troubleshoot a software issue
http://support.apple.com/kb/ht1199
If the issue does not appear to be related to preferences, a login item, or a kext file, and still persists in Safe Mode, there may be an issue with a cache file in your home folder:
1. From the Finder's Go menu, choose Home.
2. Open the Library folder.
3. Drag the Caches folder to the desktop.
4. Attempt to reproduce the issue.
5. If issue is resolved, drag the Caches folder to the Trash.
6. If issue persists, from the Finder's Go menu, choose Go To Folder.
7. Go to this folder: /Library
8. Drag the Caches folder to the desktop.
9. Attempt to reproduce the issue.
10. If issue is resolved, drag the Caches folder to the Trash.
11. If issue persists, go to step 4.
Thanks,

How do I clear the browsing history on my iPad?

How do I clear the browsing history on my iPad 2?

Settings > Safari > Clear History (and Clear Cookies And Data if you want to clear them as well).
If you also want to clear your search history (i.e. the words/phrases that you've typed in the search box) then you may also need to close Safari completely : from the home screen (i.e. not with Safari 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Safari app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.

How can I clear the stored browsing history in iCloud?

As the headline says, how can I clear the stored browsing history in iCloud?
After resetting my iPhone, previous history came back as soon as I signed in with iCloud on it. I would really like this to not occur.

The only place that Thunderbird gets suggested addresses is from your address books. I have seen some not show up in the books because some key info was never stored when the contact was saved.
Sometimes you can start a new message and when the bad contact shows up select it. Create the message and save it to drafts. Then you can go to the Draft folder open the draft message by right clicking and select Open Message in Tab. Then click the star to the right of the contact and it will open the contact edit button. From there you can delete the contact.
This does not always work though.
