java - Spliting by regex or ebnf -

i've got string like:

create person +fname : string, +lname: string, -age:int; 

is there possibility split regex or ebnf? mean things [a-za-z0-9] (things don't know) stored in array?

in other words, using regexp:

^create [a-za-z][a-za-z0-9]* [s|b]?[+|[-]|=][a-za-z][a-za-z0-9]*[ ]?:[ ]?[a-za-z][a-za-z0-9]*(, [s|b]?[+|[-]|=][a-za-z][a-za-z0-9]*[ ]?:[ ]?[a-za-z][a-za-z0-9]*)*; 

i want obtain array:

• person
• +
• fname
• string
• +
• lname
• string
• -
• age
• int

regards

you can try split way

string[] tokens = "create person +fname : string, +lname: string, -age:int;"         .split("[\\s:;,]+|(?<=[+\\-])");         //split on set of characters containing spaces:;, or after + or -.  (string s : tokens)     system.out.println("=> " + s); 

output:

=> create => person => + => fname => string => + => lname => string => - => age => int 

as can see put create @ start of array start iterating tokens[1].

you try add ^create\\s part of splitting rule, produce empty string @ start of tokens array, won't solve anything.
