JavaIO流——简单对文件的写入及读取（三）

public static void copyFile(String srcFilename, String destFilename) throws IOException {
        FileReader fReader = new FileReader(srcFilename);
        FileWriter fWriter = new FileWriter(destFilename);
        
        char[] buffer = new char[1024];
        int len = 0;
        while((len = fReader.read(buffer)) != -1) {
            fWriter.write(buffer);
        }
        fReader.close();
        fWriter.close();
        System.out.println("done");
    }

copyFile("C:\\Users\\Administrator\\Desktop\\whereveryouare.txt", "C:\\Users\\Administrator\\Desktop\\Favourite.txt");
