Android Question memory usages between a class and a module

This question has nothing to do with Java. It is better to edit the thread title.
Code itself doesn't require memory. The objects referenced from the process global variables will not be released until the variables point to a different object. It is very unlikely that you should do anything special to release the memory.

Sorry Erel.

I should clarify. Not talking about process global's.
I did modify the thread title but I do believe this has everything to do with Java.

If I have a 3000 lines in a module, NOT a class... and call one method. Does Java load all 3000 lines to find that one method?
OR... Did it just load it on startup? Did I waste the RAM for 3000 lines of code to call a sub with 30 lines of code?

If i Have class and do not instantiate it? Not used it at the moment. Maybe never used in the current configuration. Is my class in memory not being used but waiting? Or does java wait for me to make the call and then allocate memory?

Thanks.

It has nothing to do with Java programming language. It is related to how code is managed in the Dalvik virtual machine or ART runtime. You can read more about it here: http://www.anandtech.com/show/8231/a-closer-look-at-android-runtime-art-in-android-l/

The code itself doesn't have any significant impact on the memory required and there is no difference between a static module and a class.

Ah the runtime's. Clear now. Thanks.
