I want to store time slot in the arraylist. i have start time and end time. based on start time it should create time slot.
For example if start time is 09:00AM and end time is 21:00PM then it should add into arraylist like below
09:00AM
10:00AM
11:00AM
12:00PM
13:00PM
14:00PM
..... so on
21:00PM
so one user books 13:00PM to 15:00PM slots so it should not be available to another user and other slot should be available. how to compare already booking time with new array list.
Code
private void getStartHourArray() {
times = new ArrayList<TimeSlot>();
Calendar calender = Calendar.getInstance();
calender.setTimeZone(TimeZone.getTimeZone("Asia/Calcutta"));
int ti = calender.get(Calendar.HOUR_OF_DAY);
int minutes = calender.get(Calendar.MINUTE);
System.out.println(minutes);
String[] quarterHours = {
"00",
"30",
};
boolean isflag = false;
times = new ArrayList<>();
for (int i = 9; i < 22; i++) {
if (ti > 8) {
for (int j = 0; j < 2; j++) {
if ((i == ti && minutes < Integer.parseInt(quarterHours[j])) || (i != ti) || isflag == true) {
isflag = true;
String time = i + ":" + quarterHours[j];
if (i < 10) {
time = "0" + time;
}
String hourFormat = i + ":" + quarterHours[j];
if (i < 12) {
hourFormat = time + " AM";
} else
hourFormat = time + " PM";
TimeSlot t = new TimeSlot();
t.time = hourFormat;
t.isAvailable = "Available";
times.add(t);
}
}
}
}
if (times != null) {
load.setVisibility(View.GONE);
}
}
Time Slot model class
public class TimeSlot {
public String time;
public String isAvailable;
}
Try something like this :
String firstDate = "26/02/2019";
String firstTime = "00:00 AM";
String secondDate = "26/02/2019";
String secondTime = "12:00 PM";
String format = "dd/MM/yyyy hh:mm a";
SimpleDateFormat sdf = new SimpleDateFormat(format);
Date dateObj1 = sdf.parse(firstDate + " " + firstTime);
Date dateObj2 = sdf.parse(secondDate + " " + secondTime);
System.out.println("Date Start: "+dateObj1);
System.out.println("Date End: "+dateObj2);
long dif = dateObj1.getTime();
while (dif < dateObj2.getTime()) {
Date slot = new Date(dif);
System.out.println("Hour Slot --->" + slot);
dif += 3600000;
}
This will give you a time slot for each hour, add this in ArrayList and when any user select time then remove that from ArrayList and update to the server so when next
user tries to get data it won't get the first selected user time slot.
try this:
import java.time.LocalTime;
import java.util.HashMap;
import java.util.Map;
public class PlayGround {
private Map<LocalTime, Boolean> slots = new HashMap();
public static void main(String[] args) {
PlayGround client = new PlayGround();
client.initializeSlots();
client.allocateSlots("10:00", "13:00");
//this shouldn't be available
client.allocateSlots("11:00", "12:00");
//not sure if u want this to be available. since it is start when the 1st just finished.
client.allocateSlots("13:00", "15:00");
client.allocateSlots("16:00", "18:00");
}
private void initializeSlots() {
LocalTime time = LocalTime.of(9, 0);
slots.put(time, true);
for (int i = 1; i < 24; i++) {
slots.put(time.plusHours(i), true);
}
}
private void allocateSlots(String strTime, String edTime) {
LocalTime startTime = LocalTime.parse(strTime);
LocalTime endTime = LocalTime.parse(edTime);
while (startTime.isBefore(endTime)) {
//check if the time slots between start and end time are available
if (!slots.get(startTime) || !slots.get(endTime)) {
System.out.println("slots not available" + " start time: " + strTime + " end time: " + edTime);
return;
}
startTime = startTime.plusHours(1);
endTime = endTime.minusHours(1);
}
System.out.println("slots are available" + " start time: " + strTime + " end time: " + edTime);
//then here u can mark all slots between to unavailable.
startTime = LocalTime.parse(strTime);
endTime = LocalTime.parse(edTime);
while (startTime.isBefore(endTime)) {
slots.put(startTime, false);
slots.put(endTime, false);
startTime = startTime.plusHours(1);
endTime = endTime.minusHours(1);
}
}
}

I`m currently trying to obtain a CountDownTimer based on the time in milliseconds of a Calendar object. The startTimer function works, so does the timerSort function. The thing is that when the timer gets initialized with the timeLeft value, it never start from a value lower than 60 seconds. This eventually causes delays bigger than 10 seconds. any suggestions?
Thank you.
Code:
private void startTimer(String x){
counter = new CountDownTimer(timeLeft,1000) {
#Override
public void onTick(long millisUntilFinished) {
timeLeft = millisUntilFinished;
updateCountdownText();
}
#Override
public void onFinish() {
timerRunning = false;
int comp = Integer.parseInt(x);
Toast.makeText(getApplicationContext(), "Alarm received!", Toast.LENGTH_LONG).show();
cal[comp].add(Calendar.MINUTE,rec[comp]);
//Update txt file
int month = cal[comp].get(Calendar.MONTH)+1;
int day = cal[comp].get(Calendar.DAY_OF_MONTH);
String data = cal[comp].get(Calendar.HOUR_OF_DAY) + ","
+cal[comp].get(Calendar.MINUTE) + ","
+day+ "," + month + ","
+cal[comp].get(Calendar.YEAR) + "," + rec[comp] + ",";

I want to set text by date and incrementing loop, and when the day changes looping start from the beginning.
Example
1. day 1 =
a. nameFile 110920190001
b. nameFile 110920190002, etc.
2. day 2 =
a. nameFile 120920190001
b. nameFile 120920190002, etc.
Code
Date documentsDate = Calendar.getInstance().getTime();
SimpleDateFormat documentDates = new SimpleDateFormat("ddMMyy");
String setTitleDocument = documentDates.format(documentsDate);
for(int i = 1; i <= 1000; i++) {
String countDocument = String.format("%04d", i);
textNameDocument.setText("Document " + setTitleDocument + countDocument);
}
Just put the Date Initialization in the for loop for it to always take the new Instance of the date.
public static void replace(String s) {
for (int i = 1; i <= 1000; i++) {
Date documentsDate = Calendar.getInstance().getTime();
SimpleDateFormat documentDates = new SimpleDateFormat("ddMMyy");
String setTitleDocument = documentDates.format(documentsDate);
String countDocument = String.format("%04d", i);
textNameDocument.setText("Document " + setTitleDocument + countDocument);
}
}
I've been implementing an app, and was doing a DAO class with a function, which would return all events on current day. But, I have a small bug. For example: we have 2 events - event1(02:00-03:00) and event2(14:00-16:00). And we want event1 to be the first in the row. Okay, we have implemented a sort which does it, but! event2 is 1516024800000 ms and event1 is 1542618000000.

I am trying to get date doing calculations. For that I'm using Calendar cal = Calendar.getInstance();I am using this import import java.util.Calendar; When the app comes to onResume I am calling a method. In that method, the first line is getting Instance(). But for some reason, I am getting this error(ANR).

These are the two methods i call. what is wrong?
Why you not try:
public class MainActivity extends AppCompatActivity
{
Calendar c = Calendar.getInstance();
#Override
protected void onCreate(Bundle savedInstanceState) {
}
}
Edit:
I think you're using:
import java.util.GregorianCalendar;
You try (add or) instead of:
import java.util.Calendar;

The result always output with error:

The string '[1month ]' always missing. Please check if I'm missing something in code?
Thanks
In your code, you have .appendSuffix("month", "months") where "month" is the singular form, "months" is the plural form.
Your test only parses the plural forms:
else if( token.contains("months") ) {
...
}
In this case, the test fails because it is only 1 month and therefore singular.
Update your testing code to parse both singular and plural form and it should work!
