Hide Password From Console Window Java Asterisk Password Or Block Inputted String Being Displayed
提问by Colin O'Croidheagain
public class Login {
protected static String user, pass, host;
Object conn;
public void Login() throws SQLException
{
try {
Class.forName ("com.mysql.jdbc.Driver");
} catch (ClassNotFoundException e) {
System.out.println ("Could not load the driver");
}
Scanner sc = new Scanner(System.in);
Console console = System.console();
System.out.println("Please Enter Username");
user = sc.next();
System.out.println("Please Enter Password");
pass = sc.nextLine();
System.out.println("Please Enter Host/IP Address");
host = sc.next();
System.out.println("Attempting Log In");
Connection conn = (Connection) DriverManager.getConnection
("jdbc:mysql://"+host+":3306/chessdb", user, pass);
Just bit of help, been looking around online at blocking the password being shown on the console window. Is there a simple method of either the inputted text not appearing at all or else an asterisk to cover the input of the password field only?
只是有点帮助，一直在网上寻找阻止控制台窗口上显示的密码。是否有一种简单的方法，要么输入的文本根本不出现，要么只用星号覆盖密码字段的输入？

Use the readPassword()method.
使用readPassword()方法。
instead of using scannerlike
而不是像使用扫描仪
System.out.println("Please Enter Password");
pass = sc.nextLine();
use:
利用：
System.out.println("Please Enter Password");
char[] passString = Console.readPassword();
String pass = new String(passString );

java.io.Consolehas a method for reading passwords with output disabled: Console#readPassword.
java.io.Console有一种在禁用输出的情况下读取密码的方法：Console#readPassword。
