People two replaceAll calls will normally develop the exact same end result, no matter what x is. However, it is important to note which the two typical expressions are not a similar:
so "indent" specifies the amount Place to allocate to the string that follows it inside the parameter list.
5 @powersource97, %.*s indicates you are examining the precision price from an argument, and precision is the maximum amount of characters to become printed, and %*s you are looking at the width worth from an argument, which happens to be the bare minimum number os figures to be printed.

If the worth to be output is fewer than 4 character positions wide, the value is true justified in the sector by default.
If the value is larger than four character positions wide, the sector width expands to support the right quantity of figures.
