Importing Java Date Class

I have the most basic problem. Try to get the system date. My code is this;

import java.util.Date;

Date sysdate = new Date();
System.out.println(sysdate);

It gives me the error: Syntax error on token "import", assert expected

And also I have found this on web;

import java.util.Date;

public class DateDemo {
   public static void main(String args[]) {
      // Instantiate a Date object
      Date date = new Date();

      // display time and date using toString()
      System.out.println(date.toString());
   }
}

It gives the same error.

The solution should be very basic but I couldn't find it.

Thanks for your help.
