在控制台窗口中隐藏密码输入

Question

当我输入我的密码到控制台窗口时，它是可见的，无论如何这可以改变，以便它不可见？这是我的代码：

    String user, pass, host;

    Scanner sc = new Scanner(System.in);
    System.out.println("Type userid, password, hostname or ipaddress: ");
    user = sc.next();
    pass = sc.next();
    host = sc.next();
    System.out.println(user + " " + pass + " " + host);
    Methods md = new Methods();
    md.createTable(user, pass, host);

使用Console readPassword()方法：

 char[] passwd = System.console().readPassword("[%s]", "Password:");
