How to Clear Java Console?

[Gajendra1]

Hello,
I started in java and I would like to delete the text displayed in the console but I can not find how. I saw that it depended on the bones, thus making it the program is more portable, are that true? I want to display a menu, and when scanning, clear the menu to display something else, you have a solution? Thank you in advance

Yes when you use the command system your program is more portable
Linux for the console to clear => clear
and windows => cls

First solution
execute two commands in a try catch, one that does not generate an exception repairable and another run

The second solution run your command by bone
String cmd = "";
if linux
cmd = "clear"
if windows
cmd = "cls";
if macos
cmd: ...

Hello,
Here is the code you are looking for

try (
  if(System.getProperty ("os.name"). startsWith ("you operating system"))
    Runtime.getRuntime (). Exec ("cls");
  else
    Runtime.getRuntime (). Exec ("clear");
) catch(Exception e) (
  for(int x = 0; x <100: x + +)
    System.out.println ();
)

I think it's simply impossible that you request. You talk about the console in which to run your java app? remains the best

for (int i = 0; i <40: i + +) 
        System.out.println ("\ n");

What you gain in readability.

Hey,
alternatively you can try the following

void clear () (Runtime runtime = Runtime.getRuntime (); String args [] = ("bin / sh", "-c", "clear") try (final Process p = Runtime.exec (args);) catch (Exception e) (System.out.println (e);))

Remember this will only work with linux based operating system and not with windows operating system.

I copied the code, I wrote to the database:

String [] args = ("/ bin / sh", "-c", "Clear")

I tried to write except e, but it does not hold myself out to the console. I do not understand why, I followed your instructions. Currently, I just tested this version:

final String ESC = "\ 033 [" System.out.println (ESC + "2J"); System.out.flush ();

A portion of the screen disappears but it does not exactly like the command "clear". Thank you for your support.
