Making String to java.util.Date

[Farakh khan]

I am getting date from HTML form i.e.

String days=req.getParameter("days");
String months=req.getParameter("months");
String year=req.getParameter("year");

String job_start=days+"-"+months+"-"+year;
String job_end=days1+"-"+months1+"-"+year1;

How can I convert and compare with todays date?

My Code:
=========

String query5="select sysdate from dual";
PreparedStatement ps5=cnn.prepareStatement(query5);
		
rs=ps5.executeQuery();
if(rs.next()){		
java.util.Date today_date=rs.getDate(1);

	if(job_start.after(today_date)){
	//option
	}else{
	//option
	}

What I did is; certainly its wrong aproach as:

1. I am trying to write String instead of java.util.Date
2. I am getting today date with oracle and don't know as to how can in get from Java

Hi!

java.util.Date has many deprecated methods, so I advise you to use java.util.GregorianCalendar.

import java.util.GregorianCalendar;

public class DateTest {

	public static void main(String[] args) {
		int dayOfMonth = 19;
		int month = 10; // month is zero based
		int year = 2009;
		
		// First date
		GregorianCalendar gc1 = 
			new GregorianCalendar(year, month, dayOfMonth);
		// Second date
		GregorianCalendar gc2 = 
			new GregorianCalendar(year, month, dayOfMonth);
		
		
		System.out.println(gc1.compareTo(gc2));
	}
}

Take a look in the following link to understand the compare() method: http://java.sun.com/javase/6/docs/api/java/util/Calendar.html#compareTo%28java.util.Calendar%29

Also notice that if you have the dates represented in String, you can compare them using the equals() method.

Or check out DateFormat and its most-often used subclass SimpleDateFormat.
