FilelO 04: Echo to ArrayList Write a FileI004 class with a method named readFileToArrayList() that takes a filename (as a String) and returns an ArrayList of Strings. For each line in the file, add it as a separate element in the ArrayList. Do not include the newline at the end of each line. Use a BufferedReader object to read the file contents. If an exception is thrown, display an informative message and return an empty ArrayList. Examples File1084 driveri new File1004(); driver1.readFileToArrayList( "poem.txt" ) // returns (an ArrayList of Strings with 3 elements): ("Two roads diverged in a wood and I", "I took the one less trave led by", "And that has made all the difference"} FileI004 driver2 new FileI084(); driver2.readFileToArrayList( "bogusFilename.txt" ); // returns an empty ArrayList

I need this ASAP
I am supposed to you try-catch statements for this code but keep getting an error this is the code i have so far:
public class FileIO04
{
public ArrayList<String> readFileToArrayList(String filename) throws Exception
{
File file = new File(filename);
BufferedReader buffer = new BufferedReader(new FileReader(file));
String line;
ArrayList<String> list = new ArrayList<String>();
while ((line = buffer.readLine()) != null)
{
list.add(line);
}
return list;
}
