java - Split regex in Scala keeping delimiter -

i'm trying split string using regex rules:

the string should split 2 the first part containing @ least 2 characters
the second part made of characters starting first number (after second character)

e.g. ab1234 = ab , 1234 , c56789 = c5 , 6789 , zyx3939y = zyx , 3939y

i have regex working, loses character splitting on:

val t = request.number.split("(?<=.{2})[0-9]{1}", 2)

println(t(0), t(1))

gives:

(ab,234) (c5,789) (ezy,9393y)

what correct regex , there easier way of doing this?

you better off using span , splitat methods on string.

val (twofirst, rest) = request.number.splitat(2) val (nonumber, tail) = rest.span(!_.isdigit) (twofirst + nonumber, tail)

the first val splits input after second character. second val splits input finds digit.
