Hi,

Is there any way to clear screen of the standard output[Dos] in java




*Edited for a more meningfull title
Give your topic a descriptive title, NOT "Help" or "Plz Help Me" or "I'm a noob"
Or "General Java" in a Java forum is kind of useless

if your using something like bluej a really easy way to do it is this

//the \ might be the other way, i cant remember
System.out.println(\f);

I'm pretty certain that's Unix-only, but i'd be glad if i were wrong..

you're right must be based on XCurse library as its name implies
Sorry
i'll have another look around

The general consensus is to just do System.out.println() 20 times.

OK, this one is not OS specific

Unfortunately:

Is JLine a full-featured curses implementation?

No: JLine has no ability to position the cursor on the console. It might someday evolve into a plausible Java curses implementation.
Known Bugs

* Clearing the screen (CTRL-L) doesn't currently work on Windows.

So G00se is there an easy way to send a <CTRL>L by System.out.print) ?

Not that i know of i'm afraid. KYA's answer is probably as good as it gets on Windows.

Oh hang on, there's a faint possibility: have a look at Powershell for Windows, which is a free .NET-based extension from Microsoft, giving Unix-like control over a command line shell. There could be something in there ...

I tried

char ctrlL = 11;
System.out.print(ctrlL);

but without success

Yeah when I had a requirement to do this I just outputted a bunch of new lines and had the new output appear at the bottom of the shell instead of the top.

Don't tell me KYA is right

The general consensus is to just do System.out.println() 20 times.

It's a workaround...but he's right.
