As already stated in the title, I would like to know if there is an easy way to combine ItemStacks?
 

My problem at the moment is that I have a list with ItemStacks and want to combine them,
which means if the list contains 10 times of stone with a count of 10.
form that I want to make a list with 2 times of stone from it which means the count of the items in total are the same so i have two stack with the count 64 and 36.
is this possible/ is there a simple way to do that?

there isn't a function that does that already.

however writing your own helper function shouldn't be that hard

don't forget to handle the case when the ItemStacks contain different Items, or Items with non-64 maximum stack sizes

Look at ItemStackHandler#insertItem for an example of how to do this.

thanks for the good ideas
