calculate the price with two same dates but different input data formats

I have the requirement to calculate the price with two same dates but different input data formats. I am hoping for the same result. How can make the below-mentioned code so that output should be the same?
Sample code-calculation
String str="14-04-2021"; // Current date.
SimpleDateFormat df = new SimpleDateFormat("dd-MMM-yyyy");
Date startDate = df.parse(str);
output while pricing logic calculation = 43.06
Date date = new Date(); // System date.
while calculating some price logic = 42.904
public double getCalculatedProductTotalPriceBasedOnRdd(double prdTotalPrice, String pPMAnnualNetPrice, String rdd) throws ParseException {
Date startDate;
if (null != rdd) {
//startDate=new Date();
SimpleDateFormat df = new SimpleDateFormat("dd-MMM-yyyy");
startDate = df.parse(rdd);
} else {
startDate = new Date();
}
Calendar cal = Calendar.getInstance();
cal.setTime(startDate);
cal.set(Calendar.MILLISECOND, 0);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.HOUR, 0);
Date sDate=cal.getTime();
int year = cal.get(Calendar.YEAR);
cal.set(Calendar.YEAR, year);
int days = calculateDaysBetweenTwoDates(startDate);
boolean leapYear = cal.getActualMaximum(Calendar.DAY_OF_YEAR) > 365;
if (null != pPMAnnualNetPrice) {
if (leapYear) {
prdTotalPrice = (Double.parseDouble(pPMAnnualNetPrice) * days) / 366;
} else {
prdTotalPrice = (Double.parseDouble(pPMAnnualNetPrice) * days) / 365;
}
}
return prdTotalPrice;
}

Start using new java.time APIs, instead of old java.util.Date. There is a good article about this.
Following is the demo code:
public class Test {
public static void main(String[] args) throws Exception {
double price = calculate(42.0, "147", "14-04-2021");
System.out.println(price);
price = calculate(42.0, "147", null);
System.out.println(price);
}
static double calculate(double prdTotalPrice, String pPMAnnualNetPrice, String rdd) {
LocalDate startDate;
if (null != rdd) {
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MM-yyyy");
startDate = LocalDate.parse(rdd, formatter);
} else {
startDate = LocalDate.now();
}
// int days = calculateDaysBetweenTwoDates(startDate);
int days = startDate.getDayOfYear();
boolean leapYear = startDate.isLeapYear();
if (null != pPMAnnualNetPrice) {
if (leapYear) {
prdTotalPrice = (Double.parseDouble(pPMAnnualNetPrice) * days) / 366;
} else {
prdTotalPrice = (Double.parseDouble(pPMAnnualNetPrice) * days) / 365;
}
}
return prdTotalPrice;
}
}
Output:
41.88493150684931
41.88493150684931

How to get all events from SQlite database in Alamkanak Android-Week-View library ? (i keep getting single Event)?

I am trying to add events dynamically from the my SQLite database , but i get a single event in my Week-view which it is the last event i add in the database , i am using Alamkanak Week-View , i stuck with problem and try many ways , please help guys .
mWeekView.setMonthChangeListener(new MonthLoader.MonthChangeListener() {
#Override
public List<? extends WeekViewEvent> onMonthChange(int newYear, int newMonth) {
ArrayList<WeekViewEvent> lastevents = new ArrayList<WeekViewEvent>();
lastevents = loadDateFromJson(newYear,newMonth);
events.addAll(loadDateFromJson(newYear,newMonth));
return events;
}
} );
}
public ArrayList<WeekViewEvent> getmNewEvents(int year , int month ) {
// Parse time.
SimpleDateFormat sdf = new SimpleDateFormat("HH:MM");
Date start = new Date();
Date end = new Date();
start = getMyTime();
try {
end = sdf.parse(new Event().getEndTime());
} catch (ParseException e) {
e.printStackTrace();
}
Calendar now = Calendar.getInstance();
Calendar startTime = (Calendar) now.clone();
startTime.setTimeInMillis(start.getTime());
startTime.set(Calendar.YEAR, now.get(Calendar.YEAR));
startTime.set(Calendar.MONTH, now.get(Calendar.MONTH));
startTime.set(Calendar.DAY_OF_MONTH, getMyDate());
Calendar endTime = (Calendar) startTime.clone();
endTime.add(Calendar.HOUR_OF_DAY, 3);
// Create an week view event.
ArrayList<WeekViewEvent> ThisMonthsEvents = new ArrayList<WeekViewEvent>();
WeekViewEvent weekViewEvent =new WeekViewEvent(1,"Raouf",startTime,endTime);
mNewEvents.add(weekViewEvent);
for (int i = 0; i < mNewEvents.size(); i++) {
mNewEvents.get(i).getStartTime().get(Calendar.MONTH);
if((mNewEvents.get(i).getStartTime().get(Calendar.MONTH) == month)&&(mNewEvents.get(i).getStartTime().get(Calendar.YEAR) == year))
ThisMonthsEvents.add(mNewEvents.get(i));
}
ArrayList<WeekViewEvent> matchedEvents = new ArrayList<WeekViewEvent>();
for (WeekViewEvent event : mNewEvents) {
if (eventMatches(event, year, month)) {
matchedEvents.add(event);
}
}
mWeekView.notifyDatasetChanged();
return ThisMonthsEvents;
}
// here how i am getting dates from my SQlite Database
public int getMyDate() {
DBconexion db = new DBconexion(this);
SQLiteDatabase db2 = db.getReadableDatabase();
Cursor cur = db2.rawQuery("SELECT * FROM " + Table_name, null);
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd-mm-yyyy");
// looping through all rows and adding to list
String date = null;
Date Date = new Date();
ArrayList<String> dateStringList = new ArrayList<String>();
ArrayList<Date> dateList = new ArrayList<Date>();
int DayOfMonth = 0;
while (cur.moveToNext()) {
dateStringList.add(cur.getString(9));
}
for (String dateString : dateStringList) {
try {
dateList.add(simpleDateFormat.parse(dateString));
} catch (ParseException e) {
e.printStackTrace();
}
}
for (Date datee : dateList) {
DayOfMonth = datee.getDate();
}
return DayOfMonth;
}

i find how to solve this , i use JSONArrays and it works perfectly
here is the code maybe someone will need it!
public List<WeekViewEvent> loadDateFromJson(int year , int month) {
DBconexion dBconexion = new DBconexion(this);
#SuppressLint("SimpleDateFormat") SimpleDateFormat sdfD = new SimpleDateFormat("yy-MM-dd");
#SuppressLint("SimpleDateFormat") SimpleDateFormat sdfT = new SimpleDateFormat("HH:mm");
try {
JSONObject jo = dBconexion.getDateTime();
JSONArray Datejason = jo.getJSONArray("Date");
JSONArray Timejason = jo.getJSONArray("Time");
JSONArray endTimejason = jo.getJSONArray("End Time");
JSONArray Namejason = jo.getJSONArray("Name");
for (int i = 0; i < Datejason.length(); i++) {
//set date
String sd = (String) Datejason.get(i);
Date dfj = sdfD.parse(sd);
int Day = dfj.getDate();
int Month = dfj.getMonth() - 0;
int Year = dfj.getYear();
//set time
String st = (String) Timejason.get(i);
Date tfj = sdfT.parse(st);
int Hour = tfj.getHours();
int Minute = tfj.getMinutes();
String endTimeP = (String) endTimejason.getString(i);
int endTimePeriod = Integer.valueOf(endTimeP);
//set name
String Name = (String) Namejason.getString(i);
//Rand Colors for Events
Random rand = new Random();
int r = rand.nextInt(255);
int g = rand.nextInt(255);
int b = rand.nextInt(255);
int randomColor = Color.rgb(r,g,b);
if(Color.rgb(r,g,b) == getResources().getColor(R.color.white)){
randomColor = getResources().getColor(R.color.red);
}
//Set StarTime
Calendar startTime = Calendar.getInstance();
startTime.set(Calendar.HOUR_OF_DAY, Hour);
startTime.set(Calendar.MINUTE, Minute);
startTime.set(Calendar.YEAR, year);
startTime.set(Calendar.MONTH, Month);
startTime.set(Calendar.DAY_OF_MONTH, Day);
Calendar endTime = (Calendar) startTime.clone();
endTime.add(Calendar.HOUR_OF_DAY, endTimePeriod);
WeekViewEvent weekViewEvent = new WeekViewEvent(1, Name, startTime, endTime);
weekViewEvent.setColor(randomColor);
myEvent.add(weekViewEvent);
}
} catch (JSONException e) {
e.printStackTrace();
} catch (ParseException e) {
e.printStackTrace();
}
return myEvent;
}
onMonthChange will look like
mWeekView.setMonthChangeListener(new MonthLoader.MonthChangeListener() {
#Override
public List<? extends WeekViewEvent> onMonthChange(int newYear, int newMonth) {
List<WeekViewEvent> lastone = new ArrayList<WeekViewEvent> ();
lastone = loadDateFromJson( newYear , newMonth);
events.addAll(lastone);
ArrayList<WeekViewEvent> matchedEvents = new ArrayList<WeekViewEvent>();
for (WeekViewEvent event : events) {
if (eventMatches(event, newYear, newMonth)) {
matchedEvents.add(event);
}
}
return matchedEvents;
}
} );
}

Check if a given time-stamp lies between two time-stamp in android

I want to check if a given time-stamp lies between two time-stamp
Below is my code:
public static boolean isTimeBetweenTwoTime(String initialTime, String finalTime, String currentTime) throws ParseException {
String reg = "^([0-1][0-9]|2[0-3]):([0-5][0-9]):([0-5][0-9])$";
if (initialTime.matches(reg) && finalTime.matches(reg) && currentTime.matches(reg)) {
boolean valid = false;
//Start Time
java.util.Date inTime = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss").parse(initialTime);
Calendar calendar1 = Calendar.getInstance();
calendar1.setTime(inTime);
//Current Time
java.util.Date checkTime = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss").parse(currentTime);
Calendar calendar3 = Calendar.getInstance();
calendar3.setTime(checkTime);
//End Time
java.util.Date finTime = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss").parse(finalTime);
Calendar calendar2 = Calendar.getInstance();
calendar2.setTime(finTime);
if (finalTime.compareTo(initialTime) < 0) {
calendar2.add(Calendar.DATE, 1);
calendar3.add(Calendar.DATE, 1);
}
java.util.Date actualTime = calendar3.getTime();
if ((actualTime.after(calendar1.getTime()) || actualTime.compareTo(calendar1.getTime()) == 0)&& actualTime.before(calendar2.getTime())) {
valid = true;
}
return valid;
} else {
throw new IllegalArgumentException("Not a valid time, expecting MM/dd/yyyy HH:mm:ss format");
}
}
But Its not working for me, Please Help

Try this simple logic:
long mills = System.currentTimeMillis();
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
Date resultdate = new Date(mills);
String currentTime = sdf.format(resultdate);
System.out.println(sdf.format(resultdate));
try{
java.util.Date inTime1 = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss").parse(initialTime);
java.util.Date inTime2 = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss").parse(finalTime);
java.util.Date inTime3 = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss").parse(currentTime);
if (inTime3.getTime() > inTime1.getTime() && inTime3.getTime() < inTime2.getTime()){
Log.e("TimeDifference","inTime3 is between inTime1 and inTime2");
return true;
}else{
Log.e("TimeDifference","in Else Condition");
return false;
}
}catch (Exception e){
e.printStackTrace();
return false;

Android check days between two day-times

Hello everyone i try to check between days two daytimes
i have for example 12/10/2014 and 12/15/2015 datetimes.I wrote some code witch can to check different days between there two daytimes
this is a my source
public String getDateDiffString(Date dateOne, Date dateTwo) {
long timeOne = dateOne.getTime();
long timeTwo = dateTwo.getTime();
long oneDay = 1000 * 60 * 60 * 24;
long delta = (timeTwo - timeOne) / oneDay;
if (delta > 0) {
return String.valueOf(delta);
} else {
delta *= -1;
return String.valueOf(delta);
}
}
this code working perfect but i want to increase days for example 12/10/2014, 12/11,2014.....12/20/2014 between first and second daytimes.i i also wrote code but result is between first date and second days -1(between 12/19/2014)
this is a my source
SimpleDateFormat df = new SimpleDateFormat("MM/dd/yyyy");
Date _d;
try {
SimpleDateFormat new_df = new SimpleDateFormat("d MMM");
_d = df.parse(timeInfo.getTimeformat().get(0));
Date _d1 = df.parse(timeInfo.getEndTimeFormat().get(0));
String datetimeis = getDateDiffString(_d1, _d);
int differentdays = Integer.parseInt(datetimeis);
Log.e("Different is ", "" + differentdays);
for (int k = 0; k < differentdays; k++) {
String datetimeformat = dateFormatter(timeInfo.getStartTimePeriod().get(0));
Date datetime = new_df.parse(datetimeformat);
Calendar cal = Calendar.getInstance();
cal.setTime(datetime);
cal.add(Calendar.DATE, k);
datetime = cal.getTime();
String ttime = new_df.format(datetime);
ApishaDaysAdapter.add(ttime);
ApishaHollsAdapter.add(timeInfo.getHole());
String start_time = timeInfo.getTime();
start_time = start_time.replace(",", "\n");
ApishaTimesAdapter.add(start_time);
timeInfo.setStartTimePeriod(ttime);
System.out.println(ttime);
}
} catch (ParseException e) {
e.printStackTrace();
}
}
how i can solve my problem?if anyone knows solution please help me
i want to increase days [12 -20] and not [12-19)

How to automate selection of a particular date from calendar in selenium using java

I have a case in which I have to pick 3 days back date from the calendar.How to automate this case using selenium.I am using java with selenium for automation..

1) Assumption is that you can write the date in the input field and calendar is only the icon. You can have helper method something like this
public String threeDaysBefore(){
String threeDaysBefore = "";
Date date = new Date();
Calendar cal = Calendar.getInstance();
cal.setTime(date);
cal.add(Calendar.DAY_OF_YEAR, -3);
Date before = cal.getTime();
SimpleDateFormat formatter = new SimpleDateFormat("dd.MM.yyyy HH:mm");
threeDaysBefore = formatter.format(before);
return threeDaysBefore;
}
And later in the code
WebElement calendarManualInput = driver.findElement...// find the manual input field
calendarManualInput.sendKeys(threeDaysBefore());
2) If you can only click the calendar, It would be little more tricky. You still need the String, but little different:
public String threeDaysBefore(){
String threeDaysBefore = "";
Date date = new Date();
Calendar cal = Calendar.getInstance();
cal.setTime(date);
cal.add(Calendar.DAY_OF_YEAR, -3);
Date before = cal.getTime();
SimpleDateFormat formatter = new SimpleDateFormat("dd");
threeDaysBefore = formatter.format(before);
return threeDaysBefore;
}
But the above has little catch. If the date is 1.4. then it will return you "29" which could be interpreted as 29.4. which you dont want to happen. So later in the code you will probably have to do this
//this will click three days before
Date today = new Date();
Date minusThree = new Date();
Calendar now = Calendar.getInstance();
now.setTime(today);
Calendar before = Calendar.getInstance();
before.setTime(minusThree);
before.add(Calendar.DAY_OF_YEAR, -3);
int monthNow = now.get(Calendar.MONTH);
int monthBefore = before.get(Calendar.MONTH);
if (monthBefore < monthNow){
// click previous month in the calendar tooltip on page
}
WebElement dateToSelect = driver.findElement(By.xpath("//span[text()='"+threeDaysBefore()+"']"));
dateToSelect.click();
