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);
}
