How to add days to java.sql.date?

Question

Here is my program, I tried

java.sql.Date logicalDate;
Calendar c = Calendar.getInstance(); 
c.setTime(logicalDate); 
c.add(Calendar.DATE, 1);

Answer 1

Calendar#getTime returns a java.util.Date representation of the Calendar. You really need to use Calendar#getTimeInMillis instead

java.sql.Date startDate= new java.sql.Date(c.getTimeInMillis())
