How to design a simple student exam violation handling system in Java?

Introduction:
In the field of education, examinations are a test of students’ learning achievements and a test of students’ integrity. However, sometimes students violate regulations, such as cheating, plagiarism, etc., which not only damages the fairness of the exam, but also has a negative impact on students' character and learning attitude. In order to better supervise student violations and deal with them in a timely manner, it is very necessary to design a simple student examination violation processing system.

1. Requirements Analysis
Before starting system design, you first need to clarify the system requirements, which will help determine the system's functions and performance. For the student examination violation processing system, the main requirements are as follows:

1. Student information management: including student name, student number, class and other information.
2. Examination information management: including examination subjects, examination time, examination location and other information.
3. Irregular behavior entry: Enter students' illegal behavior, such as cheating, plagiarism, etc., and record relevant evidence.
4. Handling of violations: Handle the entered violations, including warnings, serious warnings, demerits, etc.
5. Query statistics function: You can query based on student number, examination subjects and other conditions, and can collect statistics on illegal behavior records.

2. System Design
When designing the system, it is necessary to consider the system structure, functional modules and data storage.

1. System structure design:
   Considering that the student examination violation processing system is relatively simple, a three-layer architecture can be adopted, which is divided into user interface layer, business logic layer and data access layer.
2. User interface layer: Responsible for interacting with users, displaying system functions through a graphical interface, and receiving information input by users.
3. Business logic layer: Responsible for processing user requests, implementing various functions of the system, and calling the data access layer to operate data.
4. Data access layer: Responsible for persistent storage of data. A database can usually be used to store data such as student information, examination information, and violation records.
5. Functional module design:
   Based on demand analysis, the following functional modules can be designed:
6. Student information management module: Provides the functions of entering, modifying, deleting and querying student information.
7. Examination information management module: Provides the functions of entering, modifying, deleting and querying examination information.
8. Violation entry module: Provides the entry function for violations, including entering student ID numbers, types of violations, and relevant evidence.
9. Illegal behavior processing module: handle according to the entered illegal behavior records, and provide warning, serious warning, demerit and other processing methods.
10. Query statistics module: Provides the function of querying student violation records based on conditions and statistics of query results.
11. Data storage design:
    Data storage can use a relational database, such as MySQL, to store data such as student information, examination information, and violation records.

3. Technical Implementation
When implementing technology, you can choose appropriate development tools and frameworks, such as Java language, Spring framework and MySQL database.

1. Front-end interface design:
   Use Java's Swing or JavaFX and other toolkits to design the user interface of the student examination violation processing system, including input boxes, buttons, tables and other components.
2. Back-end business implementation:
   Use Java language and Spring framework to implement various functional modules of the system. You can define student entity classes and exam entity classes, use frameworks such as Hibernate to interact with the database, and provide corresponding service interfaces.
3. Database design:
   Use MySQL database, create the corresponding table structure according to the requirements in the data storage design, and use JDBC or persistence framework to access the database.

4. System Testing and Optimization
After completing system development, it is very important to conduct system testing. Testing can include unit testing, functional testing, performance testing, etc. to ensure the stability and reliability of the system. If there are problems or room for optimization, repair and optimize them in a timely manner.

Summary:
Through the technology implementation of Java language, Spring framework and MySQL database, we can design a simple student examination violation processing system. The system can easily manage student information, examination information and violation records, and provides corresponding functional modules and query statistics functions to help educational institutions better supervise student violations and maintain the fairness of examinations and student integrity.
