星号字符串，屏蔽密码

我正在为 ATM 机创建这个简单的登录代码。输入用户名和密码并登录，效果非常好。由于我没有连接到数据库或外部文本文件，并且只有 1 个用户，因此它只是用 Java 代码简单地编写。但是，当您输入密码“p4ss”时，我希望它被屏蔽，因此您不应在键入时在屏幕上看到它，而应该看到“* * * *”或“ ”只是空白（就像在 Linux 上输入 pass 时一样）。

目前我的代码如下所示：

    String user;
    String pass;            
    System.out.print("User: ");
    user = Keyboard.readString();
    System.out.print("Pass: ");
    pass = Keyboard.readString();

    if ((user.equals("Admin")) && (pass.equals("p4ss")))            
    {       
        menu();      
    }    
    else
    {       
        out.println("Wrong username or password.");
    }

非常感谢我能得到的任何帮助。

原文

I'm creating this simple login code for an ATM machine.
You enter username and password and you logs in, that works just great. Since I'm not connecting to a database or an external text file and I've just got 1 user, it's just written plainly in the Java code. But when you enter the password "p4ss" I want it to be masked, so instead of seing it on the screen while typing you should see "* * * *" or " " just blank (Like when you enter pass on Linux).

Currently my code looks like this:

    String user;
    String pass;            
    System.out.print("User: ");
    user = Keyboard.readString();
    System.out.print("Pass: ");
    pass = Keyboard.readString();

    if ((user.equals("Admin")) && (pass.equals("p4ss")))            
    {       
        menu();      
    }    
    else
    {       
        out.println("Wrong username or password.");
    }

Would appreciate any help I could get.
