preface
For the students of computer major, the course design of student achievement management system must be very impressive. Design, computer, coding, report writing, defense and a series of processes, although very simple, but also can comprehensively use some of the knowledge we have learned.
Today to review the following topic, using Java SE to achieve the topic, but also to make up the original class did not write a good regret.
Although very simple, but to just dabble in programming learning, or has the certain difficulty, should not only consider print interface, also want to consider condition judgment, looping statements, input and output control, and so on techniques, so simply implemented here, convenient for beginners friends to a reference (interface is ugly to my problem, don’t too entanglements, Go down can adjust 😂, we only focus on function implementation 🤣).
For the student score management system, it can be divided into the following functions:
- Record student scores
- Student performance statistics
- Find student scores
- Revision of student grades
- Delete student scores
- Sort by average
- Show all grades
- Exiting the management System
Once in the system, we should have the system menu, and then follow the prompts to choose what we want to do.
- Record student scores
The function is to input students’ performance information every time, or add input new student performance information on the basis of the current data;
- Student performance statistics
It mainly carries on the statistics to the student’s achievement, then outputs the average score, and prints out the corresponding information;
- Find student scores
According to the input student number to find the corresponding students related results information;
- Revision of student grades
According to the input student number to modify the corresponding student’s score;
- Delete student scores
According to the student id, delete the corresponding student’s score information;
- Sort by average
In descending order of average score;
- Show all grades
Facilitate all student scores and then print them out;
- Exiting the management System
Exit menu;
Function design and implementation
The main interface
It is mainly to print out the selection menu of system functions, and then enter different sub-function modules according to our input;

Although the function is relatively simple, but still need a certain amount of time to complete. In addition, this design is only for a running process, once the program terminates, the input data can not be saved, this point needs to be noted. Later, we will consider adding file writing or database to realize the course design, so as to save the data we have entered.
