> Hello,
> In this method, we first try to separate the string into three parts and validate each
part of the string,then pass the validated whole string to a SimpleDateFormat object which
do the real parsing job.It seems likely that the validating work and the parsing work are
duplicate. And each time to invoke the java.sql.Time.valueOf() method, we need to get a new
instance of SimpleDateFormat,this is inefficient because constructing a new SimpleDateFormat
is costly.
