I want to check if a date has the format "yyyy-MM-dd". date should equal("""anyInt-anyInt-anyInt""").
With which symbol should I replace anyInt in java?
Regex: \\d{4}-\\d{2}-\\d{2}
\\d
matches any digit (exactly one)
{x}
is number of occurrences
\\d{4}
=> matches four digits
\\d{2}
=> matches two digits
etc.
\\d+
=> matches unlimited number of digits (at least one)
\\d*
=> matches unlimited number of digits (zero or more)
