What is a regular expression that matches the string in which the digits 0 to 9, a comma, and a semi-colon ? I'm looking to use it in Java:
word.matches ("^ [[1-9,;] $") // or something like that ... I am new to regular expressions.
You almost are, you just left 0 and forgot the quantifier.
word.matches ("^ [0-9,;] + $")
