I am trying to get a count of lines that have been processed by a lambda iterating over lines in a BufferedReader.
Is there a way to get a count without writing the 2nd lambda to get just the line count?
final BufferedReader inReader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8")); inReader.lines().forEach(line -> { // do something with the line });
Can I get a count also in the above code block? I am using Java 11.

try this:
AtomicLong count = new AtomicLong(); lines.stream().forEach(line -> { count.getAndIncrement(); // do something with line; });
