I know I've been looking for a way to easily clear the console without installing a library. I just found the escape sequence for a backspace and it actually clears the screen. In some of the other topics for this same problem it seemed nobody knew about this, they were either using something else to do it or just moving down enough lines to not see the text that was printed out before.
System.out.print("This is a test");
for(int i=0; i<300; i++)
{
System.out.print("\010");
System.out.print(" ");
System.out.print("\010");
}
System.out.println();
System.out.println("^The text is gone");
