How to implement a simple student homework submission system using Java?

With the advancement and development of education, student assignment submission system has become a necessary tool, especially in the online education environment. In this article, we will introduce how to use Java language to implement a simple student homework submission system.

  1. Understand the requirements and design structure

Before we start writing code, we should be clear about the specific requirements and the design structure of the entire system. The student assignment submission system consists of a backend and a frontend. The backend mainly completes tasks such as data storage, processing requests and providing API interfaces, while the frontend is mainly responsible for providing user interaction methods and communicating with the backend.

In the entire system, a user has many assignments. Each assignment can be composed of multiple questions, and each question includes two functions: submission and viewing.

  1. Determine technologies and tools

Java is a very popular programming language. It has powerful data processing and data storage capabilities, so it can be well implemented by students. The backend for the job submission system. In this project, we also need to use the MySQL database for data storage and the Spring Boot framework to build the web application.

  1. Build a development environment

Building a development environment is the next thing to do. For this, we should install JDK, MySQL and Intellij IDEA development environment. After the installation is complete, create a new project and import the dependency libraries of Spring Boot and MySQL.

  1. Database design

When designing the database, we can create three tables, each table represents a data entity: students, assignments and questions. The student table stores students' basic information, including student ID, name, grade and other fields. The job table stores job information, including job ID, job name, deadline and other fields. The question table stores question information, including question ID, question name, question type, score and other fields. Use foreign keys to associate tables.

  1. Write Java code

Next, we need to write Java code to implement the back-end program, store student, homework and question information in the database, and provide an API interface , so that the front-end application can interact with the back-end data. Specifically, we need to write the controller, service, and repository for students, assignments, questions, and assignment submissions, which are used to process front-end requests, process business logic, and access database operations respectively.

  1. Write API documentation

After completing the coding, we need to write documentation for the API interface. This will help other developers understand how our API interface works and how to use it. We can use Swagger or other tools to automatically generate API interface documents.

  1. Writing front-end code

Finally, we need to write front-end code to provide users with a good user interaction method and user experience. We can use front-end frameworks such as ReactJS, Angular or VueJS to achieve this.

Summary:

In this article, we discussed how to implement a simple student homework submission system using Java language. By using Java programming technology, MySQL database and Spring Boot framework, we successfully implemented the backend of the system and wrote API interface documents for it. Finally, we also wrote front-end applications using front-end frameworks such as ReactJS. In this way, we learned how to design and develop a complete web application.
