I have been pulling my hair for this since quite long time. I have researched for an hour on how to clear a console in Java.
All I found was dirty hacking either by printing a bunch of lines or executing this
Runtime.getruntime.exec("cls/clear"); However, nothing seems to be working for me. Isn't there really any a way of clearing the console in Java like in C (clrscr();). Isn't there any external library by which this can be achieved.
Please let me know if anyone has ever done this before using a proper function, library etc. instead of dirty hacking.

public static void clrscr(){ //Clears Screen in java try { if (System.getProperty("os.name").contains("Windows")) new ProcessBuilder("cmd", "/c", "cls").inheritIO().start().waitFor(); else Runtime.getRuntime().exec("clear"); } catch (IOException | InterruptedException ex) {} }
Console clear() The clear() method clears the console. The clear() method also write "Console was cleared" in the console.
You can clear the console inside Eclipse using the 'Clear' command - it's accessible from the toolbar or the right-click menu...
If your terminal supports ANSI escape codes, this clears the screen and moves the cursor to the first row, first column:
System.out.print("\033[H\033[2J"); System.out.flush(); This works on almost all UNIX terminals and terminal emulators. The Windows cmd.exe does not interprete ANSI escape codes.
