如何将用户名、密码和密码与文本文件进行比较以登录java

   public static void main(String[] args) {

       String username = "username2";

       String password = "password2";

       try (BufferedReader br = new BufferedReader(new FileReader("users.txt"))) {

           String line;

           boolean isAuthenticated = false;

           while ((line = br.readLine()) != null) {

               String[] parts = line.split(",");

               String storedUsername = parts[0];

               String storedPassword = parts[1];

               if (username.equals(storedUsername) && password.equals(storedPassword)) {

                   isAuthenticated = true;

                   break;

               }

           }

           if (isAuthenticated) {

               System.out.println("Login successful");

           } else {

               System.out.println("Invalid username or password");

           }

       } catch (IOException e) {

           System.out.println("Error reading file: " + e.getMessage());

       }

   }
