Review Comment:
> It seems that the String.format is more readable here
This optimization has been done from a performance perspective. The
performance of String.format is relatively poor and triggers an array
expansion, which can be referenced in issue #5804 . However, readability has
been reduced.Performance enhancement should be considered as the first priority.
