How to read from a file that was redirected

Sorry this is a simple question and I can't find what I'm looking for probably because I don't know what the keywords are.

For example I have a read.java that should be able to read how many A's there in a file called quotes.txt when I redirect the file: read < quotes.txt

How do I read from quotes.txt in java?

You can use new Scanner(System.in). It will be available as Standard Input Stream for read, represented by System.in, which is a InputStream.

You can also do

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

and use that br.
