java - Searching and sorting through an Arraylist -

i new java programmer , working on project requires me read text file has movie reviews.

once i've read file, asked search , sort through array of movies , return total number of reviews each movie average rate each movie.

the portion stuck on iterating through array list.

i using inner , outer loop , seem getting infinite loop.

i appreciate second set of eyes. have been staring @ project few days , starting not see mistakes.

here code:

import java.io.*; import java.util.*; import java.lang.*;  public class moviereviewapp {  public static void main(string[] args) {      string strline = "";     string[] result = null;     final string delimit = "\\s+\\|\\s+";     string title ="";     //int rating = (integer.valueof(- 1));      arraylist<moviereview> movies = new arraylist<moviereview>();     //arraylist<string> titles = new arraylist<string>();     //arraylist<integer> ratings = new arraylist<integer>();     //hashmap<string, integer> hm = new hashmap<string, integer>();     //listmultimap<string, integer> hm = arraylistmultimap.create();     try    {        bufferedreader f = new bufferedreader(new filereader("/users/deborahjaffe/desktop/java/midterm/moviereviewdata.txt"));          while(true)         {             strline = f.readline(); // reads line line of text file              if(strline == null)             {                 break;             }              result = strline.split(delimit, 2); //creates 2 strings              //hm.put(result[0], new integer [] {integer.valueof(result[1])});             //hm.put(result[0], integer.valueof(result[1]));              // titles.add(result[0]);             //ratings.add(integer.valueof(result[1]));              moviereview m = new moviereview(result[0]);             movies.add(m);             moviereview m2 = new moviereview();              int rating = integer.valueof(result[1]);             int sz = movies.size();               (int = 0; < sz; i++)             {                 (int j = 0; j < sz; j++)                 {                     m2 = movies.get(i);                     if (movies.contains(m2))                    {                        m2.addrating(rating);                    }                     else                    {                        movies.add(m2);                        m2.addrating(rating);                    }                }             }              movies.tostring();              //collections.sort(movies);         } //end while         f.close();         //set<string> keys = hm.keyset();        //collection<integer> values = hm.values();      } //end of try      catch(filenotfoundexception e)     {         system.out.println("error: file not found");     }     catch(ioexception e)     {         system.out.println("error opening file.");     }  } // end main  } // end class 

read file first , iterate through list or map searching, sorting etc. in above code, close while loop before iterating through list.
