使用Java编辑文本中的记录

import java.io.*;

public class TextEditor {
    public static void main(String[] args) {
        String filePath = "example.txt";
        String oldRecord = "old record";
        String newRecord = "new record";

        try {
            // 读取文件内容
            BufferedReader reader = new BufferedReader(new FileReader(filePath));
            StringBuilder fileContent = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                fileContent.append(line).append("\n");
            }
            reader.close();

            // 替换记录
            String updatedContent = fileContent.toString().replace(oldRecord, newRecord);

            // 写入更新后的内容
            BufferedWriter writer = new BufferedWriter(new FileWriter(filePath));
            writer.write(updatedContent);
            writer.close();

            System.out.println("记录已成功更新。");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
