Date date0 = new SimpleDateFormat("yyyy-MM-dd").parse("2008-10-01");
Date date1 = new SimpleDateFormat("yyyy-MM-dd").parse("2010-10-01");
Calendar cal = Calendar.getInstance();
cal.setTime(date0);
while(cal.getTime().compareTo(date1)<=0){
  //...
  cal.add(Calendar.DAY_OF_MONTH,1);
}

------解决方案--------------------
Java code
SimpleDateFormat   myFormatter   =   new   SimpleDateFormat("yyyy-MM-dd");  
java.util.Date   date=   myFormatter.parse("2010-10-01");    
java.util.Date   mydate=   myFormatter.parse("2008-10-01");  

long day=(date.getTime()-mydate.getTime())/(24*60*60*1000); 
 
System.out.println("相差的日期:"   +   day);
