The 's' replaces a single Place match at a time even so the 's+' replaces The complete Place sequence without delay with the next parameter.

All those two replaceAll calls will normally develop a similar end result, no matter what x is. However, it is important to notice which the two typical expressions aren't the exact same:

In some code that I've to maintain, I've observed a structure specifier %*s . Can any one explain to me what This can be and why it is applied?

5 @powersource97, %.*s means you are looking at the precision worth from an argument, and precision is the most variety of people to get printed, and %*s you might be reading the width price from an argument, which is the least quantity os figures for being printed.

The width is not specified in the structure string, but as yet more info another integer worth argument previous the argument that should be formatted.

The %s token lets me to insert (and likely structure) a string. See which the %s token is changed by regardless of what I move on the string following the % symbol.

If the value being output is below four character positions extensive, the value is true justified in the field by default.

If the value is larger than four character positions broad, the sector width expands to support the right quantity of figures.
