Java读取文本文件并将&替换为&amp

try {
    File file = new File("path/to/file.txt");
    FileReader fileReader = new FileReader(file);
    BufferedReader bufferedReader = new BufferedReader(fileReader);
    String line;
    StringBuilder content = new StringBuilder();
    while ((line = bufferedReader.readLine()) != null) {
        content.append(line).append("\n");
    }
    bufferedReader.close();
    String fileContent = content.toString();
    
    // 在这里进行替换操作
    
} catch (IOException e) {
    e.printStackTrace();
}

String replacedContent = fileContent.replace("&", "&");

try {
    FileWriter fileWriter = new FileWriter("path/to/file.txt");
    BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);
    bufferedWriter.write(replacedContent);
    bufferedWriter.close();
} catch (IOException e) {
    e.printStackTrace();
