Java Format Timestamp

I have below Java code to convert string format to Timestamp object
public class TestUtil{
Object result;
Public Object convertFormat(String format, String value, String type){
String format = "yyyyMMddHHmmss";
String value = "20050225144824";
SimpleDateFormat dformat = new SimpleDateFormat(format);
java.util.Date date = dformat.parse(value);
result = new Timestamp(date.getTime);
System.out.println("Result::"+ result);
}
}
Expected outcome:
I was expecting the outcome should be like below
20050225144824
Actual outcome:
2005-02-25 14:48:24.0
Could anyone tell me what I am missing here? To get "20050225144824" this result

The below code runs fine for me.
Adding few print statements to explain the different behaviors.
import java.util.Date;
import java.text.SimpleDateFormat;
import java.sql.Timestamp;
public class Main
{
public static void main(String[] args) {
String myFormat = "yyyyMMddHHmmss";
String value = "20050225144824";
try {
SimpleDateFormat dformat = new SimpleDateFormat("yyyyMMddHHmmss");
Date date = dformat.parse(value);
Timestamp ts = new Timestamp(date.getTime());
Object result = new Timestamp(date.getTime());
System.out.println("Timestamp Format with yyyyMMddHHmmss : " +dformat.format(ts));
System.out.println("Object Format with yyyyMMddHHmmss : " +result);
System.out.println("Object Format with yyyyMMddHHmmss : " +dformat.format(result));
} catch(Exception e) {
e.printStackTrace();
}
}
}
Here is the output of the different behaviors :
Timestamp Format with yyyyMMddHHmmss : 20050225144824
Object Format with yyyyMMddHHmmss : 2005-02-25 14:48:24.0
Object Format with yyyyMMddHHmmss : 20050225144824

If you expect Timestamp to return your custom output then you need to override the default Timestamp library.
Here I create CustomTimestamp.java to extend Timestamp and override its toString() method. I modified the changes according to your requirement.
public class CustomTimestamp extends Timestamp {
private int nanos;
public CustomTimestamp(long time) {
super(time);
}
#Override
public String toString () {
int year = super.getYear() + 1900;
int month = super.getMonth() + 1;
int day = super.getDate();
int hour = super.getHours();
int minute = super.getMinutes();
int second = super.getSeconds();
String yearString;
String monthString;
String dayString;
String hourString;
String minuteString;
String secondString;
String nanosString;
String zeros = "000000000";
String yearZeros = "0000";
StringBuffer timestampBuf;
if (year < 1000) {
// Add leading zeros
yearString = "" + year;
yearString = yearZeros.substring(0, (4-yearString.length())) +
yearString;
} else {
yearString = "" + year;
}
if (month < 10) {
monthString = "0" + month;
} else {
monthString = Integer.toString(month);
}
if (day < 10) {
dayString = "0" + day;
} else {
dayString = Integer.toString(day);
}
if (hour < 10) {
hourString = "0" + hour;
} else {
hourString = Integer.toString(hour);
}
if (minute < 10) {
minuteString = "0" + minute;
} else {
minuteString = Integer.toString(minute);
}
if (second < 10) {
secondString = "0" + second;
} else {
secondString = Integer.toString(second);
}
if (nanos == 0) {
nanosString = "";
} else {
nanosString = Integer.toString(nanos);
// Add leading zeros
nanosString = zeros.substring(0, (9-nanosString.length())) +
nanosString;
// Truncate trailing zeros
char[] nanosChar = new char[nanosString.length()];
nanosString.getChars(0, nanosString.length(), nanosChar, 0);
int truncIndex = 8;
while (nanosChar[truncIndex] == '0') {
truncIndex--;
}
nanosString = new String(nanosChar, 0, truncIndex + 1);
}
// do a string buffer here instead.
timestampBuf = new StringBuffer(20+nanosString.length());
timestampBuf.append(yearString);
timestampBuf.append(monthString);
timestampBuf.append(dayString);
timestampBuf.append(hourString);
timestampBuf.append(minuteString);
timestampBuf.append(secondString);
timestampBuf.append(nanosString);
return (timestampBuf.toString());
}
}
Your main class should use CustomTimestamp to get the output
try {
String format = "yyyyMMddHHmmss";
String value = "20050225144824";
SimpleDateFormat dformat = new SimpleDateFormat(format);
java.util.Date date;
date = dformat.parse(value);
Timestamp result = new CustomTimestamp(date.getTime());
System.out.println("Result::" + result);
} catch (ParseException e) {
e.printStackTrace();
}

Parse JSON and retrieve Last Element

I have the following JSON below I want to retrieve the value of the that last dateTime at the end 2011-05-01
{
"activities-log-steps":[
{"dateTime":"2011-04-27","value":5490},
{"dateTime":"2011-04-28","value":2344},
{"dateTime":"2011-04-29","value":2779},
{"dateTime":"2011-04-30","value":9196},
{"dateTime":"2011-05-01","value":15828},
{"dateTime":"2011-05-02","value":1945},
{"dateTime":"2011-05-03","value":366}
]
}
I have included the code for the current method I am using to try and retrieve that value.
protected void onPostExecute(JSONObject jsonObject) {
Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, 1);
SimpleDateFormat format1 = new SimpleDateFormat("yyyy-MM-dd");
String currentDate = format1.format(cal.getTime());
if (jsonObject != null) {
try {
name = jsonObject.getString("dateTime" + ":" + "" + currentDate + "," + "value");
Toast.makeText(getActivity(), name, Toast.LENGTH_LONG).show();
Log.d("Token Access", name);
// _access.setText("Access Token:" + heartrate);
new refresh().execute();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} else {
Toast.makeText(getActivity(), "Network Error", Toast.LENGTH_SHORT).show();
}
}
}
This is not returning a value

JSONArray ar = jsonObject.getJSONArray("activities-log-steps");
JSONObject lastObj = ar.getJSONObject(ar.size()-1);
String dateTime = lastObj.getString("dateTime");
String value = lastObj.getString("value");
You need to locate the last Object from the array activities-log-steps and then extract your JSON vars.

Converting Youtube Data API V3 video duration to hh:mm:ss format in java?

I am using Youtube data api v3 to get video information like title, views count and duration.The duration value is new to me as it's an ISO8601 date which I need to convert to a readable format like hh:mm:ss. Duration can have the following different values:
PT1S --> 00:01
PT1M --> 01:00
PT1H --> 01:00:00
PT1M1S --> 01:01
PT1H1S --> 01:00:01
PT1H1M1S --> 01:01:01
I could use Joda Time library to parse the value and calculate the duration in seconds but the library is of 500kb in size which will increase the size of my application that I don't want.

look at this code :
private static HashMap<String, String> regexMap = new HashMap<>();
private static String regex2two = "(?<=[^\\d])(\\d)(?=[^\\d])";
private static String two = "0$1";
public static void main(String[] args) {
regexMap.put("PT(\\d\\d)S", "00:$1");
regexMap.put("PT(\\d\\d)M", "$1:00");
regexMap.put("PT(\\d\\d)H", "$1:00:00");
regexMap.put("PT(\\d\\d)M(\\d\\d)S", "$1:$2");
regexMap.put("PT(\\d\\d)H(\\d\\d)S", "$1:00:$2");
regexMap.put("PT(\\d\\d)H(\\d\\d)M", "$1:$2:00");
regexMap.put("PT(\\d\\d)H(\\d\\d)M(\\d\\d)S", "$1:$2:$3");
String[] dates = { "PT1S", "PT1M", "PT1H", "PT1M1S", "PT1H1S", "PT1H1M", "PT1H1M1S", "PT10H1M13S", "PT10H1S", "PT1M11S" };
for (String date : dates) {
String d = date.replaceAll(regex2two, two);
String regex = getRegex(d);
if (regex == null) {
System.out.println(d + ": invalid");
continue;
}
String newDate = d.replaceAll(regex, regexMap.get(regex));
System.out.println(date + " : " +newDate);
}
}
private static String getRegex(String date) {
for (String r : regexMap.keySet())
if (Pattern.matches(r, date))
return r;
return null;
}
The regex2two has been used to add a leading zero0 to 1-digit numbers. you can try this demo.
In the regexMap I'v stored all 7 cases and appropriate regex-replace.

I did by myself
Let's try
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.GregorianCalendar;
import java.util.
public class YouTubeDurationUtils {
/**
*
* #param duration
* #return "01:02:30"
*/
public static String convertYouTubeDuration(String duration) {
String youtubeDuration = duration; //"PT1H2M30S"; // "PT1M13S";
Calendar c = new GregorianCalendar();
try {
DateFormat df = new SimpleDateFormat("'PT'mm'M'ss'S'");
Date d = df.parse(youtubeDuration);
c.setTime(d);
} catch (ParseException e) {
try {
DateFormat df = new SimpleDateFormat("'PT'hh'H'mm'M'ss'S'");
Date d = df.parse(youtubeDuration);
c.setTime(d);
} catch (ParseException e1) {
try {
DateFormat df = new SimpleDateFormat("'PT'ss'S'");
Date d = df.parse(youtubeDuration);
c.setTime(d);
} catch (ParseException e2) {
}
}
}
c.setTimeZone(TimeZone.getDefault());
String time = "";
if ( c.get(Calendar.HOUR) > 0 ) {
if ( String.valueOf(c.get(Calendar.HOUR)).length() == 1 ) {
time += "0" + c.get(Calendar.HOUR);
}
else {
time += c.get(Calendar.HOUR);
}
time += ":";
}
// test minute
if ( String.valueOf(c.get(Calendar.MINUTE)).length() == 1 ) {
time += "0" + c.get(Calendar.MINUTE);
}
else {
time += c.get(Calendar.MINUTE);
}
time += ":";
// test second
if ( String.valueOf(c.get(Calendar.SECOND)).length() == 1 ) {
time += "0" + c.get(Calendar.SECOND);
}
else {
time += c.get(Calendar.SECOND);
}
return time ;
}
}

Had to deal with this problem as well. I had to convert the length to milliseconds, but once you get the secs/mins/hours variables populated you can convert to any format you want:
// Test Value
$vidLength = 'PT1H23M45S';
$secs = '';
$mins = '';
$hours = '';
$inspecting = '';
for($i=(strlen($vidLength)-1); $i>0; $i--){
if(is_numeric($vidLength[$i])){
if($inspecting == 'S'){
$secs = $vidLength[$i].$secs;
}
else if($inspecting == 'M'){
$mins = $vidLength[$i].$mins;
}
else if($inspecting == 'H'){
$hours = $vidLength[$i].$hours;
}
}
else {
$inspecting = $vidLength[$i];
}
}
$lengthInMS = 1000*(($hours*60*60) + ($mins*60) + $secs);

I needed a array of all these converted duration. So I wrote the below as a workaround and also java.time.duration was not working for me, don't know why.
String[] D_uration = new String[10];
while(iteratorSearchResults.hasNext()){String Apiduration1=Apiduration.replace("PT","");
if(Apiduration.indexOf("H")>=0){
String Apiduration2=Apiduration1.replace("H",":");
if(Apiduration.indexOf("M")>=0){
String Apiduration3=Apiduration2.replace("M",":");
if(Apiduration.indexOf("S")>=0){
D_uration[i]=Apiduration3.replace("S","");
}
else{
String Apiduration4=Apiduration2.replace("M",":00");
D_uration[i]=Apiduration4;
}
}
else{
String Apiduration4=Apiduration2.replace(":",":00:");
if(Apiduration.indexOf("S")>=0){
D_uration[i]=Apiduration4.replace("S","");
}
else{
String Apiduration3=Apiduration4.replace(":00:",":00:00");
D_uration[i]=Apiduration3;
}
}
}
else{
if(Apiduration.indexOf("M")>=0){
String Apiduration2=Apiduration1.replace("M",":");
if(Apiduration.indexOf("S")>=0){
D_uration[i]=Apiduration2.replace("S","");
}
else{
String Apiduration4=Apiduration2.replace(":",":00");
D_uration[i]=Apiduration4;
}
}
else{
D_uration[i]=Apiduration1.replace("S","");
}
}
"Apiduration" is returned by the Youtube data Api in ISO8601 format.
Made some edits now i think it should work fine.

How to Disable date ranges in java calendar

In my java project i want to disable a range of dates in the java calendar and could not be successful. I'm using Netbeans as my IDE and JCalendar. Below is my code. Any help would be appreciated.
ArrayList<JSONObject> arrays = new ArrayList<JSONObject>();
for (int i = 0; i < n; i++) {
JSONObject another_json_object = vacation_home_booking_data.getJSONObject(i);
JSONObject[] jsons = new JSONObject[arrays.size()];
arrays.toArray(jsons);
String id = another_json_object.getString("id");
String vh_id = another_json_object.getString("vh_id");
String check_in = another_json_object.getString("check_in");
String check_out = another_json_object.getString("check_out");
String status = another_json_object.getString("status");
//creating two arrays of checking and checkout
//check_in_arr[i] = another_json_object.getString("check_in");
//check_out_arr[i] = another_json_object.getString("check_out");
System.out.println("ID is " + id + "vh id is " + vh_id + "check in is " + check_in + "check out is " + check_out);
DateFormat formatter = new SimpleDateFormat("yyyy-mm-dd");
try {
Date date1 = formatter.parse(check_in);
Date date2 = formatter.parse(check_out);
jCalendar1.setSelectableDateRange(date1, date2);
jCalendar1.setBackground(Color.yellow);
//jCalendar1.setSelectedDate();
} catch (ParseException ex) {
Logger.getLogger(Calender.class.getName()).log(Level.SEVERE, null, ex);
ex.printStackTrace();
}
}

Please see, if the below methods works for you:
private DateChooserCombochooser; // Initialize this somewhere
public void setMaxDate(Calendar aDate) {
chooser.setMaxDate(aDate);
}
public void setMinDate(Calendar aDate) {
chooser.setMinDate(aDate);
}
Alternatively, try using setDefaultPeriods(PeriodSet periods) method in the API.

how to remove data from hashtable for a particular date

I am trying to remove data from hashtable for a particular date,the hashtable is of type (String,vector).Initially i am checking if hashtable contains the usrDate if yes then i need to remove all the data frm hashtable only for usrDate and add the new data that is listEvents.But the contains from hashtable for other dates should not be deleted.
listEvents.addElement(eventBean);//new data is here
for (int i = 0; i < listEvents.size();i++) {
EventData e = (EventData)listEvents.elementAt(i);
}
//checking if hashtable has given date
if (listUserEvents.containsKey(usrDate)) {
Vector info = (Vector)listUserEvents.get(usrDate);
info.addElement(eventBean);
listUserEvents.put(usrDate,info);
} else {
listUserEvents.put(usrDate,listEvents);
}
i just want to add listEvents to the hashtable for the given date,without affecting the other data in hashtable which has data for some other dates.
private Hashtable getEvents(String usrDate, String timezone) {
try {
listUserEvents = getUserInfo();
listEvents = new Vector();
Calendar calendarLocalEvent = Calendar.getInstance();
// fetches time zone
TimeZone timeZoneEvent = calendarLocalEvent.getTimeZone();
System.out.println("Time Zone first-->"
+ timeZoneEvent.getDefault());
if (timezone.equals(timeZoneEvent.getDefault())) {
;
} else {
TimeZone timeZoneChange = TimeZone.getTimeZone(timezone);
System.out.println("Time Zone change-->" +timeZoneChange);
Device.setTimeZone(timeZoneChange);
}
EventList eventList = (EventList) PIM.getInstance().openPIMList(
PIM.EVENT_LIST, PIM.READ_ONLY);
Enumeration events = eventList.items();
while (events.hasMoreElements()) {
System.out.println("in while");
Event event = (Event) events.nextElement();
if (eventList.isSupportedField(Event.START)
&& event.countValues(Event.START) > 0)
{
long start = event.getDate(Event.START, 0);
SimpleDateFormat sdf = new SimpleDateFormat(
"MMM dd,yyyy HH:mm");
SimpleDateFormat sdf_start = new SimpleDateFormat("HH:mm");
SimpleDateFormat sdf_start_min = new SimpleDateFormat("HH");
String dateString = sdf.formatLocal(start);
String timeString = sdf_start.formatLocal(start);
String hour = sdf_start_min.formatLocal(start);
SimpleDateFormat sdf1 = new SimpleDateFormat("MMM dd,yyyy");
String date = sdf1.formatLocal(start);
System.out.println("dates are :" + date +"user" + usrDate);
if (usrDate.equalsIgnoreCase(date)) {
System.out.println("dates are equal:" +date);
EventData eventBean = new EventData();
if (eventList.isSupportedField(Event.END)
&& event.countValues(Event.END) > 0) {
long end = event.getDate(Event.END, 0);
SimpleDateFormat sdform = new SimpleDateFormat(
"MMM dd, yyyy HH:mm");
SimpleDateFormat sdfTime = new SimpleDateFormat(
"HH:mm");
SimpleDateFormat sdfhr = new SimpleDateFormat("HH");
String dateString1 =sdform.formatLocal(end);
String timeString1 =sdfTime.formatLocal(end);
String hr = sdfhr.formatLocal(end);
eventBean.setStartHr(hour);
eventBean.setEndHr(hr);
eventBean.setStartTime(timeString);
eventBean.setEndTime(timeString1);
eventBean.setStartDate(dateString);
eventBean.setEndDate(dateString1);
// Dialog.alert("equal startdate" + dateString);
// Dialog.alert("equal end date"+ dateString1);
}
if (eventList.isSupportedField(Event.LOCATION)
&& event.countValues(Event.LOCATION) > 0) {
String location = event
.getString(Event.LOCATION, 0);
eventBean.setLocation(location);
// Dialog.alert("equal location"+ location);
}
if (eventList.isSupportedField(Event.SUMMARY)
&& event.countValues(Event.SUMMARY) > 0) {
String subject = event.getString(Event.SUMMARY, 0);
eventBean.setSummary(subject);
// Dialog.alert("equal subject" +subject);
}
eventBean.setUserDate(usrDate);
eventBean.setTimeZone(timezone);
listEvents.addElement(eventBean);
System.out.println("the size bf hashis"
+ listEvents.size());
for (int i = 0; i < listEvents.size();i++) {
EventData e = (EventData)listEvents.elementAt(i);
System.out.println("so thesummary is ::"
+ e.getSummary());
}
// for(int i=0;i<listUserEvents.size();i++){
if (listUserEvents.containsKey(usrDate)) {
// listUserEvents.remove(usrDate);
Vector info = (Vector)listUserEvents.get(usrDate);
System.out.println("the size in getEvents is"
+ info.size());
if(info.contains(usrDate)){
System.out.println("in info");
}
info.addElement(eventBean);
System.out.println("vector size info is"
+ info.size());
listUserEvents.put(usrDate,info);
} else {
System.out.println("in else of getevent" +listEvents.size());
listUserEvents.put(usrDate,listEvents);
}
// }
} else {
// Dialog.alert("not equal");
}
}
}
Device.setTimeZone(timeZoneEvent);
Calendar calendarLocalLastEvent = Calendar.getInstance();
// fetches time zone
TimeZone timeZoneEventLast =calendarLocalLastEvent.getTimeZone();
System.out.println("Time Zone last-->"
+ timeZoneEventLast.getDefault());
} catch (PIMException e) {
// //Dialog.alert(e.getMessage());
}
System.out.println("size in hashtable " + listUserEvents.size());
return listUserEvents;
}

It must be something like this
for(int i = 0; i<listUserEvents.size();i++)
{
if (listUserEvents.containsKey(usrDate)){
listUserEvents.remove(usrDate);
}
}

Here is a simple example of how this works:
Hashtable<String, Integer> numbers = new Hashtable<String, Integer>();
numbers.put("one", 1);
numbers.put("two", 2);
if (numbers.containsKey("two")) {
numbers.put("two", 222);
}
What are you having difficulty at? Moreover what is the type of your Hashtable key? Is it java.util.Date or something else?
