java - How do I use the printf function while keeping columns organized? -

-

i'm trying print out invoice report in java project having trouble formatting sheet. code i'm having problems with.

stringbuilder sb = new stringbuilder();  sb.append(string.format("%s%s%-82s%s%10.2f%s","discount ( ","placeholder"," )", "$", 99.99, "\n"));

which prints out this

discount ( placeholder )                                                                                $     99.99

if change character length of word "placeholder," $99.99 column moved, such.

discount ( p )                                                                                $     99.99

what need code whether word "placeholder" replaced word 10 characters long or 1 character long, $99.99 needs stay in same place in correct column when print. tried modifying %s $ seems still move if placeholder changed. advice?

you try width parameter.
(15 width here):

system.out.printf("%s%15s%-82s%s%10.2f%s", "discount ( ", "placeholder", " )", "$", 99.99, "\n");

not sure if string.format uses same syntax printf though.

the output be:

discount (     placeholder )                                           $     99,99 discount (               p )                                           $     99,99

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
