Java
Read file by line
Recursively traversing directories
Traversing the directory above is a recursive method. Let's take a look at the non recursive implementation:
We can write a class to simply test:
Test results: recursion: total number of files: 189497 total time: 39328 non recursion: total number of files: 189432 total time: 37469 non recursion here is relatively better~
