本文實例講述了Java基於IO流讀取檔案的方法。分享給大家參考，具體如下：
public static void readFile(){String pathString = TEST.class.getResource("/simu").getFile();try { pathString = URLDecoder.decode(pathString, "utf-8");} catch (UnsupportedEncodingException e1) { e1.printStackTrace();}System.out.println(pathString);File file = new File(pathString,"test.txt");InputStream is = null;try { is = new FileInputStream(file);} catch (Exception e) { e.printStackTrace();}BufferedReader br = new BufferedReader(new InputStreamReader(is ));StringBuffer sb = new StringBuffer("");String b = "";try { while((b=br.readLine())!=null){ sb.append(b).append("/n"); }} catch (Exception e) { e.printStackTrace();}String bb = sb .toString();System.out.println(bb);}希望本文所述對大家Java程式設計有幫助。
