如何在java中将文件位置作为参数传递

Question

private static void saveCallers(String fName, RadioShow r) throws IOException {
        //TODO write the code to save the callers to a file
        try
        {
            FileOutputStream outStream = new FileOutputStream("C:\\Desktop\\text1.txt");
            ObjectOutputStream out = new ObjectOutputStream(outStream);
            out.writeObject(r);
            out.close();
        }
        catch(Exception e)
        {
            System.out.println("something went wrong here! : " + e);
        }

        }

它给了我一个URLClassLoaderException，所以我假设我给它一个不正确的格式？但我似乎无法弄清楚这样做的正确方法。

谢谢

确保＆＃34; C：\ Desktop \＆＃34;文件夹存在。
