Hello Sukh,

I replied to your question in the intermediate forum as well. SO, Here it goes. IF you want to read a line and then compare that with some word. You should StringTokenizer method, it breaks down the line word by word. Onto your problem. Lets say the words that you want to count are : for, else, is, are. There are 2 ways to do it. You don't have to store them in any array. For example:



let me know if this way works for you . Take care.

If the magic words are in an ArrayList you can expand on the example above a bit. Get a word, see if it's in the ArrayList, maybe find out where in the ArrayList and increment a counter in a regular int[] array. "See if it's in the ArrayList" is a hint to go read the JavaDoc. Have fun!
