[classlib][sql] Improve the performance of java.sql.Date.valueOf(String ) method
--------------------------------------------------------------------------------

                 Key: HARMONY-1359
                 URL: http://issues.apache.org/jira/browse/HARMONY-1359
             Project: Harmony
          Issue Type: Improvement
          Components: Classlib
            Reporter: Richard Liang
            Priority: Minor


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.Date.valueOf() method, we need to get a new instance
of SimpleDateFormat,this is inefficient because constructing a new SimpleDateFormat is costly.

Best regards,
Richard
