How To Mask a password input in java console
问题
我正在Java中构建一个登录系统，我试图遮蔽密码输入以提高安全性，但似乎找不到解决方法。这是我尝试做的：
用户名：
User1
密码：******
这是我的代码，以便让你了解一下：
package com.company;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner Input = new Scanner(System.in);
System.out.println("用户名：");
String Username = Input.nextLine();
System.out.println("密码：");
String Password = Input.nextLine();
}
}
英文:
I'm building a login system in Java and I'm trying to mask the password input due to security measures but can't seem to find a way around it. This is what I'm Trying to do:
Username:
User1
Password:******
Here's my code to give you an idea
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner Input = new Scanner (System.in);
System.out.println("Username:");
String Username = Input.nextLine();
System.out.println("Password:");
String Password = Input.nextLine();
}
}

尝试使用Java的readPassword()方法：
它不会用*掩盖字符，但会隐藏我们在控制台上键入的输入。
```java
cnsl = System.console();
char[] pwd = cnsl.readPassword("Password: ");
System.out.println("Password is: " + pwd);
就像这样……
英文:
Try readPassword() method of java
It doesn't mask a * but it hide the input we type to console
cnsl = System.console();
char[] pwd = cnsl.readPassword("Password: ");
System.out.println("Password is: "+pwd);
like this.......
