'One way', rather than specifically a better way..

 // String.split() available in Java 1.4+
 String[] dateParts = "2005-06-15".split("-");
 StringBuffer sb = new StringBuffer();
 for (int ii=dateParts.length-1; ii>0; ii--) {
   sb.append( dateParts[ii]  + "-" );
 }
 sb.append( dateParts[0] );
 System.out.println( sb );

HTH

You know the exact format of the input string, so you an use substring
to extract parts:
---
/**
* Converts an ISO date to dd-mm-yyyy format
* @param date An ISO format date.
* @returns The date in dd-mm-yyyy format
*/
String reverseDate(String date) { // e.g. "2005-06-15"
   return date.substring(8)) +  // "15"
          date.substring(4,8) + // "-06-"
          date.substring(0,4);  // "2005"
}
---

There are date parsing and formatting methods in the library -- maybe
something like the following would work for you?

 public class dateconv {
   public static void main(String [] asArgs)
     throws java.text.ParseException {
     java.text.DateFormat dfYMD =
       new java.text.SimpleDateFormat("yyyy-MM-dd") ;
     java.text.DateFormat dfDMY =
       new java.text.SimpleDateFormat("dd-MM-yyyy") ;

     for(int i=0; i<asArgs.length; ++i) {
       System.out.println("'" + asArgs[i] + "' => '"
           + dfDMY.format(dfYMD.parse(asArgs[i])) + "'"
         ) ;
     }
   }
 }

 jc@sarah:~/tmp$ /usr/java/jdk1.5.0_01/bin/java dateconv "2005-06-15"
 '2005-06-15' => '15-06-2005'

Can't you use the SimpleDateFormat class, and its parse(...) and
format(...) methods?
