I need to count the time it takes a function to complete in Java. How can I do that?
Note: I want to count the time a function takes, not the time the full program takes.

Long start = System.nanoTime(); methodToBeTimed(); long elapsedTime = System.nanoTime() - start;
System.nanoTime should be used to accurately measure the delta between two times for microbenchmarks... .
If you want to get current time, use java.util.Date.

I don't have IntelliJ in front of me but could it be that IntelliJ is set to do a clean compile before it runs the tests where Eclipse is set to do a make (I.e only compile changed classes)
Just a thought
Eclipse compiles on the fly (on save), so it ... .

Calling System.gc() requests that garbage collection takes place, and isn't guaranteed. The part about it not being guaranteed is interesting to me: can someone explain the exact process that takes place when you make this call?

Why System.Boolean takes 4 bytes even if it just stores one state TRUE or FALSE; which may be stored less than 4 bytes?

As an example, an array of Nullable<bool> s takes only 2 bytes.
Just for alignment isn't always present.

/usr/lib/pkginfo
/usr/share/pkgconfig
