Hello! Can anyone tell me how to make use of the End of Line constant (TT_EOL) when reading data from a file into a Vector? I understand that TT_EOL returns and int, while vectors only hold class types (Double in my case), so how can you compare the two? I would like my program to stop reading tokens into a vector when it reaches the end of the line in a text file. Here is my code, that produces an error stating that I cannot compare a String to an int:
public void dataRetrieve(String name)
/**************************************************************************
*Method Name: dataRetrieve
*
*Description: This method takes in the name variable and reads the file
* line by line, parsing each test name (String) and each test
* score (integer). For each line, it adjusts all applicable
* variables as necessary and keeps track of total tests and
* total scores by range (for each test). It will throw an IO
* exception if there are problems reading from the file.
* Reads file until no more lines.
*
*
*Precondition: Text file exists.
*
*Postcondition: Multiple variable values are updated to reflect all file
* input. Total tests are counted.

try
{
BufferedReader inputStream = new BufferedReader(new FileReader(name));
String trash = "No trash yet";
testNames = new Vector<String>();
while ((trash = inputStream.readLine()) !=null)
{
StringTokenizer st = new StringTokenizer(trash);
testNames.addElement(st.nextToken());
lineCount++;
Vector<Double> tempScores;
while(st.nextToken()!= StreamTokenizer.TT_EOL)
{
tempScores = new Vector<Double>();
tempScores.addElement(new Double(st.nextToken());
}
int index;
double sum = 0;
for(index = 0; index<tempScores.size(); index++)
{
sum = sum + tempScores.elementAt(index);
}
double average = sum/tempScores.size();
testMeans.addElement(average);
}
inputStream.close();
}
catch(IOException e)
{
System.out.println("Problem reading from file.");
}
Thanks for any/all help!
