Great video with easy to understand explanation. I have a question. I checked my hprof heap dump as I thought my application was causing memory leaks, but it turns out most of the memory is consumed by byte, char and Strings which are not from my application. How do I fix or avoid memory leaks in that case? Your response will be highly appreciated. Thanks

A static field, by itself, is not a memory leak. It's only a memory leak if memory is allocated but not released when no longer needed. If you need a list of doubles for the lifetime of the program, then keeping the data in a static field is an appropriate design. If at some point in the program execution they are no longer needed, just call List::clear.

Correction: in java 9+, do not avoid string concatenation if the whole string is computed on a single operation (i.e. not in a loop), the compiler and runtime know enough for it to be optimal

Why the populate method is not declared static, since it is only using static member?
In that case to populate the list we will not need to create the object of the class.

And when the list is no longer needed then it could be set to null, to let the garbage collector reclain it. It would not need the unloading of the class in such a case.

[JorgetePanete]

Soon to be a correction: the finally block is most of the time replaced by the try-with-resources, and the finally block will be removed in some future java release
