Clear The Console Programmatically In Java

问题

I created a sample Java application. I want to clear the window options, i.e.:

1. Register
2. Login
3. Clear

If the user presses 3 I need to programmatically clear all options. Something like Console.clear?

Is there any way that I can do this with Java?

回答1:

You will need to output a bunch of blank lines. Even in Windows/*nix, clear/cls doesn't truly clear the screen, it just prints enough blank lines that you cannot see the previous text.

回答2:

You mean you created a console application and want to clear the console (not necessarily the Eclipse console)?

If so then I guess you're looking for:

Runtime.getRuntime().exec("cls");

But be aware this will be system dependent.

回答3:

If you are working with the console, then these might prove useful. Using "backspace" character. Using process builder.
