 String, text, numbers, I/O II part

 Q: How do I parse it to date and make a date difference?? How many days in

between the String from and to?

I am always confusing with date and time.

I have 2 String, from and to

String from = "01.01.2001" //dd.MM.yyyy

String to = "01.03.2001" //dd.MM.yyyy

How do I parse it to date and make a date difference?? How many days in between

the String from and to?

Answer: 

import java.text.SimpleDateFormat;

import java.util.Date;

public class Tmp {

   public static void main( String argv[] ) throws Exception {

      long DAY = 24L * 60L * 60L * 1000L;

      SimpleDateFormat df = new SimpleDateFormat( "MM.dd.yyyy" );

      Date d1 = df.parse( "01.01.2001" );

      Date d2 = df.parse( "01.03.2001" );

      System.out.println( "The number days between:" );

      System.out.println( d1 );

      System.out.println( "and:" );

      System.out.println( d2 );

      System.out.println( "is: " + (( d2.getTime()   d1.getTime() ) / DAY )); 

   }

}

But the calculation of the difference in times may not be suitable due

to timezone issues and such. I believe there must be a better way?
