Java基於IO流讀取檔案的方法_java

本文執行個體講述了Java基於IO流讀取檔案的方法。分享給大家供大家參考，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程式設計有所協助。
