I am developing an app in eclipse ide

I want to read a text file which is in res folder line by line and initialise a HashTable whenever the app starts

All the file handing codes I found read char by char

Kindly help

private String file(){
		  InputStream is = getClass().getResourceAsStream("/database.txt");
		  StringBuffer sb = new StringBuffer();
		  int chars, i = 0;
		  while ((chars = is.read()) != -1){
		  sb.append((char) chars);
		  return sb.toString();
		  }catch (Exception e){}
		  return null;
