How to design a simple student curriculum query system in Java?

With the improvement of education level and the continuous development of schools, students have more and more courses, and it becomes more and more difficult to manage. In order to facilitate students to query their course schedule, we can design a simple student course schedule query system. This article will introduce how to use Java language for design and implementation.

First, we need to determine the functional requirements of the system. The student curriculum inquiry system mainly has the following functions:

1. Student information management: including students’ basic information and course information, such as student name, student number, major, etc.
2. Course information management: including basic information of the course, class time and location, etc.
3. Course schedule query: Students can query their course schedule by entering their student number or name.

Next, we can start the design and implementation of the system.

1. Database design

First, we need to design the database to store student information and course information. You can create two tables, one to store student information and one to store course information. The student information table includes fields such as student number, name, major, etc.; the course information table includes fields such as course number, course name, class time and location.

2. Writing Java classes

Next, we can write Java classes to implement the functions of the system. Two classes can be created, one is the student class and the other is the course class. The student category includes attributes such as student number, name, major, and related methods; the course category includes attributes such as course number, course name, class time and location, and related methods. You can use the get and set methods to set and get property values.

3. Implementation of the curriculum query function

In order to implement the curriculum query function, we can create a query class that contains a query method. In the query method, you can enter the student number or name to find the corresponding student information and obtain their course information. You can use SQL statements to query the database and return the query results to the user.

4. Writing user interface

In order to allow users to use the system conveniently, we can write a simple user interface. You can enter your student number or name through the console and call the query method in the query class to obtain the course schedule information and display the results to the user.

The above are the basic steps for designing a simple student curriculum query system. Through reasonable database design and Java class implementation, as well as a user-friendly user interface, students can easily query their course schedules. Of course, this is just a simple example, and more functions and extensions need to be considered in actual applications. I hope this article can be helpful to readers!
