使用Java中的while循环将用户输入转换为星号（如密码）

Question

Using while loop in java how can i convert user input into asterisk while it is being typed like in password. It is possible and how? Thanks.

        System.out.print("Enter password: ");

        while(true)
        {
            password = pal.nextLine();
            password = "*"; 
            System.out.print(password);
        }

This is the only idea that i have but it doesn't work

Not sure about displaying asterisks but you could make the password invisible by using the Console.readPassword method

public class Main {    

  public static void main(String[] args) {
    char passwordArray[] = System.console().readPassword("Enter password: ");
     // entered password will be stored in this array        
  }
}
