Counting times a word appears in document

Question

I am trying to read from a file and count how many times a word appears in that document.
For example if i had a list of names
Daniel Fowler
Joe Mahogony
Daniel Peterson
Chris Sim
How would you count the amount of people named Daniel and display it?
I am currently using findInLine"Daniel" but when ran no luck.
Any ideas?

deepak,
the bufferedreader reads content from the file yes?
but what method would i use to count the amount of a word in that file?
finInLine finds the word but cannot turn that into an integer. any other methods?first of all the code I had posted in my previous post should work and it uses the Scanner to read the file.
If you want to use the FileReader approach the within the code that actually reads the file line by line, you can use the String.indexOf method (as suggested by nclow) to check if a particular word is present in that line of the file. IF it is there you increment a counter.
int counter = 0;
// Read through the entire file
String currentLineFromFile = bufferedReader.readLine(); // throws IOException
while(currentLineFromFile != null)
    // Add a carriage return (line break) to preserve the file formatting.
    textFromFile.append(carriageReturn + currentLineFromFile);
    currentLineFromFile = bufferedReader.readLine(); // throws IOException
      if (currentLineFromFile.indexOf("Daniel") != -1)
            counter++
      System.out.println("No of occurances- " + counter);
}hope this helps
