我有一个问题让这个工作.它包含一个由多条信息组成的字符串.但是,当我尝试将String写入文件以便跟踪程序随时间的变化时,我收到一个拒绝访问错误:

 void writeToFile(String input) throws Exception{
            File file = new File("C:\\WeatherExports\\export.txt");
            if(!file.exists()){
                    file.createNewFile();
            }
            BufferedWriter inFile = new BufferedWriter(new FileWriter(file,true));
            try{
                    inFile.append(input);
                    inFile.newLine();
            } catch(Exception e){
                    e.printStackTrace();
            }
            inFile.close();
    }
