Can't get vector indexOf working

Question

I have a small little method that is trying to search a vector for a specific string to get its index in the vector. Below is the code for the method...
public String getMinRoundTrip(){
          String min = "Minimum";
          int minIndex = -1;
          minIndex = received.indexOf(min);
          System.out.println("DEBUG: " + minIndex);
          String outLine = (String) received.get(minIndex);
          int firstIndex = outLine.indexOf("Minimum");
          int secondIndex = outLine.indexOf(", Maximum");
          minRoundTrip = outLine.substring(firstIndex, secondIndex);
          return minRoundTrip;
I know that "Minimum" exists in the vector, but the index is always coming out with -1, so it is not being found. What am I doing wrong here? Any help would be appreciated.
Thanks in advance!

Answer 1

No, it is definitely there. I have printed the vector out and could see it in the output. I have also tried searching for other words in the vector and still get -1 returned as the index value.
This is how I am populating the vector...
BufferedReader in = new BufferedReader(new InputStreamReader(proc.getInputStream()));
String line;
received = new Vector();
while((line = in.readLine()) != null) {
System.out.println("DEBUG: " + line);
received.add(line);
It seems to populate just fine. I don't get this?
