How can I get the current system date and a value of 30 days for the current system date!

<% @ Page import = "Java. Text. *" %>

<% @ Page import = "Java. util. *" %>
<%
Simpledateformat formatter1 = new simpledateformat ("yyyy-mm-dd ");
Java. util. Date mydate = new java. util. Date ();
Long mytime = (mydate. gettime ()/1000) + 60*60*24*30;
Mydate. settime (mytime * 1000 );
String mdate = formatter1.format (mydate );
Out. println (mdate );
%>
// Define two strings to respectively obtain the current system date and add a value of 30 days to the current system date.
<%
Date = new date ();
Simpledateformat simpledateformat_date = new simpledateformat ("mm DD, YYYY ");
String systemdate = simpledateformat_date.format (date );
Long mytime = (date. gettime ()/1000) + 60*60*24*30;
Date. settime (MySQL * 1000 );
String mdate = simpledateformat_date.format (date );
%>
