Source code words and line counting in netbeans 7.x?

Question

I am Computer Science student and working on a project in java through netbeans 7.0.1 to be submitted in college, Today my faculty asked me how much your project is completed and i confidently replied that, Yes sir approx 50% completed already, he said how many lines u code, and i just go "Ummmm don't know exactly Sir", he replied, "Are you actually working or just buying it from somewhere!", my mind go blank!!! :D
I googled for this and found a WordCount Plugin for netbeans, but it does not working in NetBeans 7, or may be i do't know how exactly it works..
Any substitute for this WordCount available for NetBeans 7.x?
Or any other way, except manual counting of line in whole application?

Answer 1

It's not part of Netbeans, but I use CLOC for this and find it does a nice job - identifies different languages well, reports on how many lines are comments, how many are code and so on.

Since a 'nix-based answer has been given, in Windows you could accomplish something similar with Powershell:

get-content *.java | measure-object -line
