This Maven project implements a REST API for managing "Alien" records. The API supports basic CRUD (Create, Read, Update, Delete) operations and is implemented using Jersey Quick Start.
The database for storing the Alien data is created using JDBC, and the API is tested using Postman.

com.srinivas.Restdemo.Alien: A Java class representing the Alien entity with fields like alienid, name, and points.
com.srinivas.Restdemo.AlienResource: This class contains the RESTful API methods to handle requests.
com.srinivas.Restdemo.AlienRepository: This class handles database operations using JDBC.
