How to write a simple student leave management system using Java?

With the continuous development of society and the improvement of education level, school management work has become more and more complex. Among them, student leave management is an important part of school management. In order to improve the efficiency and accuracy of student leave management, we can use Java language to write a simple student leave management system.

This student leave management system mainly includes the following functional modules: student management, leave management, leave approval, leave inquiry, etc.

First, we need to create a student class to save student information. The student class includes the student's name, student number, class and other attributes. Students' information can be represented using classes and objects through Java's object-oriented programming ideas.

Then, we need to create a leave class to save leave information. The leave category includes attributes such as the start time, end time, and reason for leave. Similarly, through object-oriented programming ideas, classes and objects can be used to represent leave information.

Next, we need to create a leave approval class to record the approval status of leave. The leave approval category includes leave approval status, approval opinions and other attributes. Similarly, through object-oriented programming ideas, classes and objects can be used to represent the approval status of leave requests.

In the student leave management system, we need to implement the following functional modules:

1. Student management: you can add student information, modify student information, delete student information and other operations.
2. Leave management: You can add leave information, modify leave information, delete leave information and other operations.
3. Leave Approval: You can approve students' leave information, including agreeing to ask for leave, rejecting the request for leave, etc.
4. Leave Inquiry: You can query students' leave information, including querying by student number, querying by date, etc.

In the process of realizing these functions, we can use Java's object-oriented programming ideas to establish corresponding classes and objects, and implement specific operations through methods. You can use Java's collection class to store student information, leave information, and leave approval information for easy management and query.

The interface of the student leave management system can be implemented using Java graphical interface technology, such as JavaFX or Swing. You can use Java event listeners to monitor user operations and call corresponding methods to implement functions.

In short, using Java to write a simple student leave management system requires designing corresponding classes and objects to represent students, leave and leave approval information, implementing corresponding functional modules, and using Java's graphical interface technology to implement the user interface. This will improve the efficiency and accuracy of student leave management and provide a better management experience.
