Java is better suited to working within the current
screen environment, rather than clearing it.

What do you intend to happen to the 'task bar' and
other opened programs when this action happens?

i wanted it turn black

import java.awt.*;

class ClearScreen {
public static void main(String[] args) {
try {
for (
GraphicsDevice device :
GraphicsEnvironment
.getLocalGraphicsEnvironment()
.getScreenDevices()
) {
if (device.isFullScreenSupported()) {
Window window = new Window(null);
window.setBackground(Color.BLACK);
device.setFullScreenWindow(window);
}
}
Thread.sleep(10000);
} catch (java.lang.InterruptedException exc) {
// Ignore.
} finally {
System.exit(0);
}
}
}

to clear the console log see http://mindprod.com/jgloss/console.html

It is not your real estate. At best you can close frames to reveal
what was under them.

IF you want the screensaver hook to temporarily draw something else,
then later restore the original screen, you would do that in C/C++ and
link to it via JNI.

Google for saverbeans - I believe it's part of the Java Desktop Integration
Components project. It allows you to write native screensavers in Java. That
approach will work much better...

Of course, I'm assuming that the OP wants to create a screensaver, which
wasn't clear from the original post.

As I understand, it might *become* part of that, but as an
incubator project, it is not yet part of it.

Further, it supports Win and Unix, but not Mac.,
and cannot become part of the integration components
until/unless it does support Mac.

It actually just provides the 'native hooks' into the
OS' own screensaver system. The code you write for the
savers can still be plain ole' Java.

[ And I am not sure if what I said was functionally
different from what you wrote. ]

Same here. (not clear what OP wants)

If this is a console application (clear the screen), then check out this
article:
