Question

Ol'新手再来一次......我收到此消息无法找到我定义的所有文件的符号。我在下面复制了与我的问题相关的源代码：

         // Does RequestFile exist? then Process it...
     if ( !Rqst_File.exists() )
       {   // Request File DOES_NOT exist 
         message_data.append("LU62XCE0113: Request File = ") ;

感谢关于我做错事的任何和所有帮助......

由于

Answer 1

嗯，不存在任何名为FileOutputStream的方法。如果你试图创建一个FileOutputStream（cos有一个类似的类），尝试使用类似的东西：

FileOutputStream fos = new FileOutputStream(Resp_File);

等等。我看到至少发生过两次此错误。

Answer 2

看起来你正试图调用一个名为FileInputStream（）的方法

Perah你打算做FileInputStream fis = new FileInputStream(...)？

对“无法找到符号”感到困惑
