Answer 3

You can use this code

private static void Clear()
{
    try
    {
        String os = System.getProperty("os.name");

        if (os.contains("Windows"))
        {
            Runtime.getRuntime().exec("cls");
        }
        else
        {
            Runtime.getRuntime().exec("clear");
        }
    }
    catch (Exception exception)
    {
    }
}

Answer 4

Java does not provide any such functionality. Output on terminal is just a special case of redirecting standard output(standard input or standard error). As such output stream has no knowledge what the stream is redirected to.

You can use hacks to achieve your goal though. Refer this question. Best way I thing is the following

    String os = System.getProperty("os.name");

    if (os.contains("Windows"))
    {
        Runtime.getRuntime().exec("cls");
    }
    else
    {
        Runtime.getRuntime().exec("clear");
    }
