Error trying to read from a text file

Question

I am new to Java and am having a difficult time with this particular problem. I created a data.txt file, put the info into it, and placed it in the same package I am working in. When I try to run the code, I get a "System cannot find the file specified" error. I can't for the life of me figure out what I am doing wrong. The ultimate goal is to have the information read from the data file, tokenized, and then printed out using the format I have in a separate control file. Any assistance would be greatly appreciated.

package cs520.hw3.part2;


import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.StringTokenizer;


public class Test {

public static void main(String[] args)
{

    String inputFileName = "data.txt";
    FileReader fileReader = null;
    try
    {
        fileReader = new FileReader(inputFileName);
    } 
    catch (FileNotFoundException e)
    {

        e.printStackTrace();
    }

BufferedReader reader = new BufferedReader(fileReader);
String input;

try {
    input = reader.readLine();
    while (input != null)
    {
        processInputData(input);
        input = reader.readLine();
    }
} catch (IOException e) {
    e.printStackTrace();
}
try {
    fileReader.close();
} catch (IOException e) {
    e.printStackTrace();
}
}       

private static void processInputData(String data)
{
    StringTokenizer st = new StringTokenizer(data, ",");
    String senName      = st.nextToken();
    String senParty     = st.nextToken();
    String senState     = st.nextToken();
    String senYears     = st.nextToken();
    //Senator senatorDetails = 
        //new Senator(senName, senParty, senState, senYears);
    //System.out.println(senatorDetails);
}
}
