java - Parsing String with fixed-width fields but different length -


i need parse long string pattern:

1)'*'   (text,len:1) 2)accountcount  (number,len:2) 3)accountnumber1    (text,len:20) 4)accountnumber2    (text,len:20) 5)accountnumber3    (text,len:20) 6)accountnumber4    (text,len:20) ... ?)accountnumber'$accountcount'  (text,len:20) ?)'^'   (text,len:1)

as can see, accountnumber field repeated in 'accountcount' times.

what best way declare class string , set accountcount,accountnumber1,accountnumber2,accountnumber3,... properties?

using guava splitter. 

final string in = "* 3      accountnumber1      accountnumber2      accountnumber3^"; final iterable<string> accounts = splitter.fixedlength(20).trimresults().split(in.substring(3, in.length - 1);

something that. can "transform" accounts list of account object if needed.
