檔案輸出為字串示例程式碼：

• /**
       * 讀取檔案為字串
       * 
       * @return
       */
      public static String readString() {
          String str = "";
          File file = new File("C:/Users/wan7/Desktop/表單/粗集料試驗/粗集料衝擊值試驗（T0322-2000).html");
          try {
              FileInputStream in = new FileInputStream(file);
              // size 為字串的長度 ，這裡一次性讀完
              int size = in.available();
              byte[] buffer = new byte[size];
              in.read(buffer);
              in.close();
              str = new String(buffer, "utf-8");
          } catch (IOException e) {
              return null;
          }
          return str;
      }
   
  

字串輸出為檔案示例程式碼：

• /**
       * 輸出到檔案
       */
      public static void outFile(String s) {
          File file = new File("C:/Users/wan7/Desktop/11111111111.html");
          try (FileOutputStream fop = new FileOutputStream(file)) {
              // if file doesn't exists, then create it
              if (!file.exists()) {
                  file.createNewFile();
              }
              // get the content in bytes
              byte[] contentInBytes = s.getBytes();
  
              fop.write(contentInBytes);
              fop.flush();
              fop.close();
              System.out.println("Done");
          } catch (IOException e) {
              e.printStackTrace();
          }
      }
