学生投票系统java代码javaEE

学生投票系统是一个常见的应用场景，下面是一个简单的学生投票系统的Java代码示例（使用JavaEE）：

// Student.java
public class Student {
    private String name;
    private int voteCount;

    public Student(String name) {
        this.name = name;
        this.voteCount = 0;
    }

    public String getName() {
        return name;
    }

    public int getVoteCount() {
        return voteCount;
    }

    public void vote() {
        voteCount++;
    }
}

// VotingSystem.java
import java.util.ArrayList;
import java.util.List;

public class VotingSystem {
    private List<Student> students;

    public VotingSystem() {
        this.students = new ArrayList<>();
    }

    public void addStudent(Student student) {
        students.add(student);
    }

    public void vote(String studentName) {
        for (Student student : students) {
            if (student.getName().equals(studentName)) {
                student.vote();
                break;
            }
        }
    }

    public void printResults() {
        for (Student student : students) {
            System.out.println(student.getName() + ": " + student.getVoteCount());
        }
    }
}

// Main.java
public class Main {
    public static void main(String[] args) {
        VotingSystem votingSystem = new VotingSystem();

        // 添加学生
        Student student1 = new Student("Alice");
        Student student2 = new Student("Bob");
        votingSystem.addStudent(student1);
        votingSystem.addStudent(student2);

        // 进行投票
        votingSystem.vote("Alice");
        votingSystem.vote("Bob");
        votingSystem.vote("Alice");

        // 打印结果
        votingSystem.printResults();
    }
}

这个示例代码实现了一个简单的学生投票系统，包括学生类（Student）、投票系统类（VotingSystem）和主程序类（Main）。你可以根据实际需求进行扩展和修改。
