First Thank you so much for your video. After your video I just went through java.nio.files jar and I noticed that nio is much faster than the io. Now my question is how to handle the data which I read using nio with the use of streams like this example. (printing large file data using stream, removing duplicate words from the large file, replace some word (x) with some other word(y)) To solve these kind of problems how can I use streams using nio package while working with the large file.

this is not accurate and you cant guarantee times accuracy because depends of the processor-threads . if you run this multiples times, you will get multiples different results....
