comparing current date and time with got date and time .

Question

date = formatter.parse(dateInString); 			
	time = (Date) formatterTime.parse(timeInString); 	
	Calendar current = Calendar.getInstance();   
	Calendar cal = Calendar.getInstance(); 	
	/* cal.set(DatePicker.g, pickerDate.getMonth(), pickerDate.getDayOfMonth(), pickerTime.getCurrentHour(), 	
			 * pickerTime.getCurrentMinute(), 00); 				 */ 
	cal.set(date.getYear(),date.getMonth(),date.getDay(),time.getHours(),time.getMinutes());//error i think so   
				if (cal.compareTo(current) <= 0) 				
{ 					// setAlarm(cal); 				
	// The set Date/Time already passed 					
Toast.makeText(getApplicationContext(), "Invalid Date/Time", Toast.LENGTH_LONG).show(); 	
			} 				else 				{ 	
				 setAlarm(cal); 				
	 db.addContact(new Contact_details(name1, mobile_number1, home_number1, company_name1, jobtitle1, emailid1, date, time)); 	
			}

OK can't help you further as I now realize that this is for Android. Did you follow my suggestion about the breakpoint?

public void onClick(View v) { //Date picker if (v == setdate) { // Process to get Current Date final Calendar c = Calendar.getInstance(); mYear = c.get(Calendar.YEAR); mMonth = c.get(Calendar.MONTH); mDay = c.get(Calendar.DAY_OF_MONTH); // Launch Date Picker Dialog dpd = new DatePickerDialog(this new DatePickerDialog.OnDateSetListener() { @Override public void onDateSet(DatePicker view int year int monthOfYear int dayOfMonth) { // Display Selected date in textbox setdate.setText(dayOfMonth + - + (monthOfYear + 1) + - + year); } } mYear mMonth mDay); dpd.show(); } if (v == settime) { // Process to get Current Time final Calendar c = Calendar.getInstance(); mHour = c.get(Calendar.HOUR_OF_DAY); mMinute = c.get(Calendar.MINUTE); // Launch Time Picker Dialog TimePickerDialog tpd = new TimePickerDialog(this new TimePickerDialog.OnTimeSetListener() { @Override public void onTimeSet(TimePicker view int hourOfDay int minute) { // Display Selected time in textbox settime.setText(hourOfDay + : + minute); } } mHour mMinute false); tpd.show(); } if (v == save_contacts) { final String name1 = name.getText().toString(); final String mobile_number1 = mobile_number.getText().toString(); final String home_number1 = home_number.getText().toString(); final String company_name1 = company_name.getText().toString(); final String jobtitle1 = jobtitle.getText().toString(); final String emailid1 = emailid.getText().toString(); SimpleDateFormat formatter = new SimpleDateFormat(dd-MM-yyyy); // SimpleDateFormat formatterDate = new SimpleDateFormat(dd/MM/yyyy); SimpleDateFormat formatterTime = new SimpleDateFormat(HH:mm); String dateInString = setdate.getText().toString(); String timeInString = settime.getText().toString(); Date date = null; Date time = null; Date todayDate; try { date = formatter.parse(dateInString); time = (Date) formatterTime.parse(timeInString); //// current_date=formatter.parse() //Calendar current = Calendar.getInstance(); // todayDate = formatter.parse(formatter.format(new Date() )); /*Calendar cal = Calendar.getInstance(); cal.set(date.getYear()+1900 date.getMonth() date.getDay()time.getHours() time.getMinutes()); */ if (date.compareTo(todayDate) { // setAlarm(cal); // The set Date/Time already passed // setAlarm(cal); Toast.makeText(getApplicationContext() Invalid Date/Time Toast.LENGTH_LONG).show(); } else { // setAlarm(cal); db.addContact(new Contact_details(name1 mobile_number1 home_number1 company_name1 jobtitle1 emailid1 date time)); Toast.makeText(getApplicationContext()  + date +  + time Toast.LENGTH_LONG).show(); } } catch (java.text.ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } this is full code and i will get date and time using pickers and i need to compare with current date and time

This is a little bit of a guess based on the fact that there is a getInstance() call. 'current' and 'cal' will follow each other; if 'current' changes 'cal' changes and if 'cal' changes 'current' changes. I suggest that you put a breakpoint on if(cal.CompareTo(current) Below a simple example (I could not find a Calendar control so this is a bit of a guess how to get the info out of the Calendar control) DateTime current = new DateTime(current.year current.month current.day); DateTime cal = new DateTime(date.getYear() date.getMonth() date.getDay()); if (cal { } This only takes date into account not time. You can add the rest.
