Clearing concile window

[Striver2000]

I have a question when I send something to the concile window to be printed out like forexample if i say System.out.println("Hello") when I run this once Hello appears if I run it again Hello appears with the previous Hello so it looks like this

Hello

Hello

Is there a way I can clear the concile output window so no matter how many times I run this without killing the program Hello will show once is there some kind of code to clear the concile window before printing Hello to the screen?

I think you mean console. You could go to the dos properties and get the inital line size of the screen then just loop that number of times calling System.out.println(); to push the screen output off the screen.

public class D{
 public static void main(String[] args){
  System.out.println("X");
  for(int screenlines = 0; screenlines <= 10; screenlines++){
  System.out.println();
  }
 }
}

I guess when you said the consile window you mean't the command line. If so, It is possible that you can control the attributes like color and stuff, and I'm pretty sure you can clear the console by setting some of the attributes using java code.

I think you can do it by ANSI escape sequences but I believe you have to modify some of you system files to support it.
I don't really know how to do this, so no code is available from me.

My dos properties says intial lines 25 so when i run the following code
the X ends up one line almost off screen. So i guess to get it off screen entirely i would need to change screenlines <= 21 to screenlines <= 22 or a higher value .

public class D{
 public static void main(String[] args){
  System.out.println("X");
  for(int screenlines = 0; screenlines <= 21; screenlines++){
  System.out.println();
  }
 }
}

Striver2000. I had the same problem a while ago.

You can get a hook to dos but i never figured out a way to execute the cls command via java to clear the screen.

Check this site out. It shows you how to control attributes of the command line, I think!
