I Need help with Java Regular Expressions?
I have a String "TA520"
and "TA011"
and I want to get the number without the leading digit using regular expressions. So I need the "520"
and the "11"
without the leading 0
digits. I have the expression aString = aString.replace("TA0* , "");
but this doesn't work. How would I do this with regular expressions in Java? Thank you.
The problem here is that String.replace
does not use regular expressions.
You need to use String.replaceAll
.
aString.replaceAll("^TA0*", "")
or alternatively, using replaceFirst
:
aString.replaceFirst("^TA0*", "")
This strips away the leading "TA" plus any optional leading zeros.
