Those two replaceAll calls will usually produce a similar consequence, no matter what x is. However, it is important to notice which the two typical expressions are not the exact same:
In a few code that I've to keep up, I've witnessed a format specifier %*s . Can any individual explain to me what This really is and why it is actually applied?
5 @powersource97, %.*s usually means you are examining the precision worth from an argument, and precision is the most variety of characters being printed, and %*s you might be reading the width worth from an argument, which is the least quantity os figures to generally be printed.

The width just isn't specified in the structure string, but as an extra integer worth argument previous the argument that needs to be formatted.
If the worth for being output is lower than four character positions broad, the worth is right justified in the sector by default.
This way it get more info could stand By itself. Furnishing an example that was comparable to the instance from the query would also be a in addition.
