help please

[sunklay69]

I was doing a program an I need help on one method
I need to check for a number and count how many times it is on the file
the only thing that I don't know how to do is the part that I need to read and count.

I'm doing it in java.

So you don't know how to read or count the file? Surely that means that you haven't attempted it because those 2 points are pretty much it.

Just break it down. First you need to obviously read the file in character by character. Then when you encounter a certain type of character simply increment an integer. That's pretty much it.

You should check out InputStreamReader which is passed as an object to a BufferedReader

I know how to read the only thing is that I don't know how to count
Example how many a's are in the document?

this is the thing I trying to do but I think I'm not doing it right. Help me in everything that you can.

thank you

Read the file character by character.
Create an empty hashtable (chars as keys, ints as values).

for each character in file do
-- look in hash for character
-- if exists increment counter
loop
