Simpliest jar ever made, it just count how many lines of your project (java project) are actual lines of code. It also distinguish between comment lines, close lines '}' and blank lines.
to run it, put the LOC.jar file among a folder called "new", in which, the .java files to check should be placed in. Once you run it, an "output.txt" will be generated with all the info.
Have fun!
PD: if you want to see same feedback, run it writting something like "java -jar "LOC.jar"", if not just double-click that jar file
