아... txt파일 에 한글이 있으면 못 읽어오나요?

Question

String txtData = "";
  String line = "";
  StringBuilder sb = null;
  
  try {
   File file = new File("경로 + txtData.txt");
   
   FileInputStream fis = new FileInputStream(file);
   InputStreamReader isr = new InputStreamReader(fis,"euc-kr");
   BufferedReader br = new BufferedReader(isr);   
   while ((line = br.readLine()) != null) {
    sb.append(line+ " ");
   }
   br.close();
   isr.close();
   fis.close();
   txtData = sb.toString();

이렇게 소스를 사용했는데 에러가 나네요..

왜 에러가 나는건지 모르겠네요..

InputStreamReader 에서 인코딩해서 읽은다음 Buffer로 넘기고..했는데..

Answer 1

StringBuilder 객체인 sb가 null인데요.

StringBuilder sb = null; 이 부분을

StringBuilder sb = new StringBuilder(); 로 고쳐보세요.
