I'm trying to create process animation in my console app. Is it possible to rewrite previous lines for this needs? I know about \r
but it works only with current line.
If it is not possible, how could I achieve animation effect? Thanks.
My console is standard Ubuntu 12.04 terminal emulator.
Thanks to @MrSmith42 I made this simple demo, which shows way to overwrite lines:
public class Flush {
public static void main(String[] args) {
for(int i = 0; i < 5; i++) {
System.out.println("**********************************");
}
// ESC[5A - cursor up 5 times
// \r - cursor return to begin of line
// ESC[J - erase to end of screen
System.out.print("\033[5A\r\033[J");
for(int i = 0; i < 5; i++) {
System.out.println("##################################");
}
}
}
That depends on your console. Lot of consols support vt100 commands which allow e.g. changing the position of the cursor or change he color of text or background.
I use it a lot to make colored debug output in my java programs to the shell.
