JAVA 讀取本地文本文件

 String encoding = "GBK";
 File file = new File("D:\\jz_activity_exchange_voucher-INSERT.txt");
 if (file.isFile() && file.exists()) { //判斷文件是否存在
 InputStreamReader read = new InputStreamReader(
 new FileInputStream(file), encoding);//考慮到編碼格式
 BufferedReader bufferedReader = new BufferedReader(read);
 String lineTxt = null;
 while ((lineTxt = bufferedReader.readLine()) != null) {
 System.out.println(lineTxt); 
 } 

 read.close();
 } else {
 System.out.println("找不到指定的文件");
 return new Success<>(false);
 }
} catch (Exception e) {
 System.out.println("讀取文件內容出錯");
 e.printStackTrace();
}
