Java prepares the test score passing judgment module of the online examination system

Java writes the test score passing judgment module of the online examination system, which requires specific code examples

With the development of network technology, more and more educational institutions and enterprises Use an online exam system to replace traditional paper exams. The online examination system provides a more convenient and efficient examination method, and can count and analyze examination results in real time. In this system, the determination of passing test scores is a very important part. This article will introduce how to use Java to write an exam score passing determination module and provide specific code examples.

The examination score passing determination module needs to determine the candidates' scores based on the set passing standards. The qualifying standard can be a fixed score line or a dynamic score line calculated through certain dynamic parameters. Below is an example where we will use a fixed score line to make the decision.

First, we need to define an Exam class to represent information about an exam, including exam subjects and exam scores. The code example is as follows:

public class Exam {
    private String subject;
    private int score;
    
    public Exam(String subject, int score) {
        this.subject = subject;
        this.score = score;
    }
    
    // 省略getter和setter方法
    
    // 判断考试成绩是否合格的方法
    public boolean isPassed(int passLine) {
        return (score >= passLine);
    }
}

Next, we need to write a ScoreProcessor class to process test scores. This class contains a method used to determine whether a set of test scores are satisfactory. The code example is as follows:

import java.util.List;

public class ScoreProcessor {
    public static boolean isAllPassed(List<Exam> exams, int passLine) {
        for (Exam exam : exams) {
            if (!exam.isPassed(passLine)) {
                return false;
            }
        }
        return true;
    }
}

The method isAllPassed in the above code receives a list of Exam objects and a passing score line as parameters, traverses each exam object in the list and calls its isPassed method for judgment. If any test score is lower than the passing score, false is returned; otherwise, true is returned.

Finally, we can write a test class to test our exam score passing determination module. The code example is as follows:

import java.util.ArrayList;
import java.util.List;

public class TestScores {
    public static void main(String[] args) {
        List<Exam> exams = new ArrayList<>();
        exams.add(new Exam("Math", 80));
        exams.add(new Exam("English", 90));
        exams.add(new Exam("Science", 70));
        
        int passLine = 75;
        
        boolean allPassed = ScoreProcessor.isAllPassed(exams, passLine);
        
        if (allPassed) {
            System.out.println("Congratulations, you passed all exams!");
        } else {
            System.out.println("Sorry, you failed in one or more exams.");
        }
    }
}

In the above code, we created three exam objects and added them to a list. Then, we set the passing score to 75, and called the isAllPassed method of the ScoreProcessor class to determine whether the test scores were qualified. Finally, the corresponding information is output according to the judgment result.

Summary:
This article introduces how to use Java to write a test score passing determination module. We define the Exam class and ScoreProcessor class to represent the exam and test score processing respectively, and finally call the appropriate method in the test class to achieve the determination. The above code is only an example, please modify and adjust according to actual needs. I hope this article can help you understand and implement the test score passing determination module of the online examination system.
