在執(zhí)行任何任務(wù)之前想要將文件復(fù)制/備份到目標(biāo)文件夾。(jdk-1.7) /*Input file path taken from properties file as string is :inputFilewhere-in inputFile is :C:\\Project\\input\\filename.txtDestination file path taken from properties file as string is : archiveFolderPath */ //Existing code : in mainif (inputFile != null) {readTextFile(new File(inputFile)); }// in readTextFile methodBufferedReader br = new BufferedReader(new FileReader(filename));我嘗試使用以下過(guò)程：：但出現(xiàn)錯(cuò)誤：錯(cuò)誤：：文件類型中的方法復(fù)制（InputStream，OutputStream）不適用于參數(shù)（字符串，字符串）//Calling method in main::copyFiles(inputFile, archiveFolderPath);//Copy method :private static void copyFiles (String inputFile, String archiveFolderPath) throws IOException { Files.copy(inputFile, archiveFolderPath); }請(qǐng)建議替代解決方案，如“文件不適用于參數(shù)（字符串，字符串）”。

您可以在對(duì)文件執(zhí)行讀取或?qū)懭氩僮髦皬?fù)制該文件。例子：-
Path origin = Paths.get("/home/fm/source.txt");
Path destination = Paths.get("/home/fm/source.bak");
//Copy source.txt to source.bak
Files.copy(origin, destination, StandardCopyOption.COPY_ATTRIBUTES, StandardCopyOption.REPLACE_EXISTING);
Files有關(guān)所有方法的詳細(xì)信息，請(qǐng)參閱javadoc copy。他們中的一些人期待CopyOption著爭(zhēng)論。CopyOption根據(jù)節(jié)目要求選擇合適的。
