OK. Is JTextArea part of Java or does it have to be imported. And if it does where am I able to get the files needed to be imported. ALSO. Just pasting this code:
[code] JTextArea jta ; jta.setText(""); [/code]
into my code will make the screen clear? I understand that its making jta of type JTextArea but I'm not understanding what jta.setText(""); does except decalre it null. Maybe I'm missing something.

I think you are missing the point completly. The code above does not clear your screen, its a TextArea used in GUI's (just like the text areas used in html to post a message on this board). The only thing this method does is clearing a TextArea.
I think you want to know how to clear your command prompt window from your application, but i'm sorry to say i don't know that. Anyone?

[code]
JTextArea jta ;
jta.setText("");
[/code]
If it's a graphics use this code example;
[code]
// Buffered Graphics
Dimension offDimension;
Image offImage;
Graphics offGraphics;
void paint()
{
// Get the Graphics of the screen and the size
Graphics g = getGraphics();
Dimension d = size();
// Create the offscreen graphics context, if no good one exists
if (offGraphics == null || d.width != offDimension.width || d.height != offDimension.height)
{
offDimension = d;
offImage = createImage(d.width,d.height);
offGraphics = offImage.getGraphics();
}
//Clear screen
offGraphics.setColor(Color.lightGray);
offGraphics.fillRect(0,0,d.width,d.height);
// Draw game objects
offGraphics.setFont(font);
offGraphics.setColor(Color.black);
offGraphics.drawString("" + ball.scoreLeft,20,d.height-2);
offGraphics.drawString("" + ball.scoreRight,d.width - 32,d.height-2);
p1.paint(offGraphics);
p2.paint(offGraphics);
ball.paint(offGraphics);
// Copy the off screen buffer to the screen.
g.drawImage(offImage, 0, 0 , this);
}
[/code]
If you need a full code example of the graphics I can mail
that to you.

I said
[red]
If it's a text example JText Area you can use this;
[/red]
[code]
JTextArea jta ;
jta.setText("");
[/code]
[red]
If it's a graphics use this code example;
[/red]
.........

You know a text area can be part of your screen. Likewise does
a graphic area be part of your screen. So let Switalla elaborate what
he wants.
