API for simple File (line count) functions in Java

Question

Hi : Given an arbitrary file (java), I want to count the lines.

This is easy enough, for example, using Apache\'s FileUtils.readLines(...) method...

Howeve

Answer 1

With Guava:

int nLines = Files.readLines(file, charset, new LineProcessor() {
  int count = 0;
  Integer getResult() {
    return count;
  }
  boolean processLine(String line) {
    count++;
    return true;
  }
});

which won't hold the whole file in memory or anything.
