Thread: Help displaying strings that appear in one text file but not another!

I'm trying to display all of the songs that appear in one text file but not another. However it doesn't display any songs. All help appreciated.
My Code:

	  public static void OnlyInIrishCharts()throws IOException
    {
		String lineFromFile, line;
		String result;
  		String words [];
  		String peices [];
  		int count = 1;
  		boolean found;
  		result = "The following singles only appear in the Irish Charts: ";
		File f1 = new File("IrishTop100Singles.txt");
		File f2 = new File("UKTop100Singles.txt");
		if (f1.exists() && f2.exists())
  		{
   			Scanner input = new Scanner(f1);
   			while(input.hasNext())
   			{
    			lineFromFile = input.nextLine();
    			words = lineFromFile.split(";");
    			Scanner input2 = new Scanner(f2);
    			found = false;
    			while(input2.hasNext() && !found)
    			{
	    			line = input2.nextLine();
	    			peices = line.split(";");
	    			if(!(words[2].equals(peices[2])) && !(words[3].equals(peices[3])))
	    			 found = true;
				}
 
				input2.close();
				if (found = false)
				{
					result += (count + ". Title: " + (words[2]) + " Artist: " + (words[3]) + "\n");
					count++;
				}
			}
 
			JOptionPane.showMessageDialog(null,result,"UK and Irish Charts",1);
			input.close();
		}
		else
  			JOptionPane.showMessageDialog(null,"File Not Found!", "Error!",0);
 
	}
