Declaring variables inside or outside of a loop
.... However, this does not apply to your example, due to the immutability of strings in java: a new instance of str will always be created in the beginning of your loop and it will have to be thrown away at the end of it, so there is no possibility to optimize there.

Why would iterating over a List be faster than indexing through it?

all in a single traversal, which is O(N).
Now, going to th...
