用Java模拟微信投票程序，可以添加姓名，投票，查询，退出，并且将数据记录在本地文件中。

好的，这个问题可以回答。以下是一个简单的Java代码示例，可以模拟微信投票程序：

import java.io.*;
import java.util.*;

public class WeChatVote {
    private static final String FILE_NAME = "votes.txt";
    private static Map<String, Integer> votes = new HashMap<>();

    public static void main(String[] args) {
        loadVotes();
        Scanner scanner = new Scanner(System.in);
        while (true) {
            System.out.println("请选择操作：");
            System.out.println("1. 添加姓名");
            System.out.println("2. 投票");
            System.out.println("3. 查询");
            System.out.println("4. 退出");
            int choice = scanner.nextInt();
            switch (choice) {
                case 1:
                    addName(scanner);
                    break;
                case 2:
                    vote(scanner);
                    break;
                case 3:
                    query(scanner);
                    break;
                case 4:
                    saveVotes();
                    System.exit(0);
                    break;
                default:
                    System.out.println("无效的选择，请重新输入");
            }
        }
    }

    private static void addName(Scanner scanner) {
        System.out.println("请输入姓名：");
        String name = scanner.next();
        if (votes.containsKey(name)) {
            System.out.println("该姓名已存在");
        } else {
            votes.put(name, 0);
            System.out.println("添加成功");
        }
    }

    private static void vote(Scanner scanner) {
        System.out.println("请输入姓名：");
        String name = scanner.next();
        if (!votes.containsKey(name)) {
            System.out.println("该姓名不存在");
        } else {
            int count = votes.get(name);
            votes.put(name, count + 1);
            System.out.println("投票成功");
        }
    }

    private static void query(Scanner scanner) {
        System.out.println("请输入姓名：");
        String name = scanner.next();
        if (!votes.containsKey(name)) {
            System.out.println("该姓名不存在");
        } else {
            int count = votes.get(name);
            System.out.println(name + " 的得票数为：" + count);
        }
    }

    private static void loadVotes() {
        try (BufferedReader reader = new BufferedReader(new FileReader(FILE_NAME))) {
            String line;
            while ((line = reader.readLine()) != null) {
                String[] parts = line.split(",");
                String name = parts[0];
                int count = Integer.parseInt(parts[1]);
                votes.put(name, count);
            }
        } catch (IOException e) {
            System.out.println("读取文件失败：" + e.getMessage());
        }
    }

    private static void saveVotes() {
        try (PrintWriter writer = new PrintWriter(new FileWriter(FILE_NAME))) {
            for (Map.Entry<String, Integer> entry : votes.entrySet()) {
                String name = entry.getKey();
                int count = entry.getValue();
                writer.println(name + "," + count);
            }
        } catch (IOException e) {
            System.out.println("保存文件失败：" + e.getMessage());
        }
    }
}

这个程序可以添加姓名、投票、查询、退出，并将数据记录在本地文件中。具体实现细节可以参考代码注释。
