I want to make an arraylist that has random numbers and make it in order from least to greatest.
How do I do this?
Try using the
Collections.sort(your_array_name)

We have customerIds, 1-5000. originally thinking of using Even/Odd, Mod %2. Are there any other algorithms available? Just curious, currently using Java Spring Boot.

I want to check if a List of characters like {a,a,d,e} is contained in a list like {a,d,e} in java. I want the answer to be false but I have no idea how to go about doing this. All help would be appreciated :)
Try using the retainAll() method and check for the result. col1.retainAll(col2) leaves all elements in col1 that are also in col2. If the size of col1 is the same before and after the call, the whole col2 is contained.

I have a fully working B-Tree, and I want to convert this into a B+tree.
Is there any way that I can achieve that without changing so much of my code? is it possible?

Nope. Significant amount of change is required. B+ tree doesn't store data pointer in non-leaf nodes.
