How do I clear the console in Java

Question

How do I clear the console in Java? This is my code but it doesn't do anything.

switch (commandTyped.toUpperCase()) {
        case "I":
            final String ANSI_CLS = "\u001b[2J";
            final String ANSI_HOME = "\u001b[H";
            System.out.print(ANSI_CLS + ANSI_HOME);
            System.out.flush();
            inventory.check();
            break;


    }

Thanks!

Clearing the console (if it can be done at all) will be intimately tied to the particular Java execution environment you're using. — Ted Hopp, Nov 23 '16 at 21:40

You can use:

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

it will clear the console

Did you try this? It usually doesn't work, because `exec()` isn't running its argument in a command line interpreter. It's also specific to Windows. – Ted Hopp Nov 23 '16 at 21:44
You can use ASCII Escape codes also to clear check this one System.out.print("\033[H\033[2J"); – ZCoder Nov 23 '16 at 21:45
That didn't work. Thanks for trying to help though! – stephenpassero Nov 23 '16 at 22:18
@Agha, that one didn't work either. – stephenpassero Nov 23 '16 at 22:20
