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.

I am fetching data from file using filestream and importing this data into oracle tables. I have column 'FT__FIRST' which is Date data type in oracle table and where i only need date values to be inserted and ignore other values. From file the date is coming in format 'YYYYMMDD'. In future if there is other values coming from file rather than Date datatype for this column and if it tries to insert into oracle table then the java code might throw an error as literal string does not match.
So to avoid this issue i want to modify my java code such that it can take only insert date format value and ignore other values. Currently i am handling only specific string from file which i know and ignoring it as they are not date format..
Java uses classes DateTimeformatter but dont know how to use it in my code..
private String createUpdateTableSql(String line, String tableName, String dateFormat, List<ColumnData> columnData) {
List<String> data = Splitter.on("|").trimResults().splitToList(line);
String ftFirst = "";
String tr = "";
String pds = "";
for (int i = 0; i < columnData.size(); i++) {
if(columnData.get(i) == null || "N.A.".equalsIgnoreCase(data.get(i)) || "N.A".equalsIgnoreCase(data.get(i)) || "UNKNOWN".equalsIgnoreCase(data.get(i))) {
continue;
}
if ("FT_FIRST".equalsIgnoreCase(columnData.get(i).getName().trim())) {
ftFirst = data.get(i);
}
if ("TR".equalsIgnoreCase(columnData.get(i).getName().trim())) {
tr = data.get(i);
}
if ("P_S_SOURCE".equalsIgnoreCase(columnData.get(i).getName().trim())) {
pds = data.get(i);
}
}
return "UPDATE " + tableName + " " +
"SET FT_FIRST=to_date('" + ftFirst + "','YYYYMMDD')" +
" WHERE TR='" + ticker +
"' AND P_S_SOURCE='" + pds + "'";
}
When you read data from file, you could parse the date field to date object like below:
// NEW CODE
private Date getDateValue(String sDate, String format) {
SimpleDateFormat sdf = new SimpleDateFormat(format);
try {
return
sdf.parse(format);
} catch (ParseException ignored) {
// TODO: Log this exception return null;
}
}
As you can see, you are parsing a string to date with an expected format yyyyMMdd (YYYYMMDD on oracle)
If parsing fails (value field does not containts the expected format) you can add the logic as you want on catch clausule or ignore error and let value as null.
Your code will be like this:
private String createUpdateTableSql(String line, String tableName, String dateFormat, List<ColumnData> columnData) {
List<String> data = Splitter.on("|").trimResults().splitToList(line);
String futNoticeFirst = "";
String ticker = "";
String pds = "";
for (int i = 0; i < columnData.size(); i++) {
if (columnData.get(i) == null || "N.A.".equalsIgnoreCase(data.get(i)) || "N.A".equalsIgnoreCase(data.get(i)) || "UNKNOWN".equalsIgnoreCase(data.get(i))) {
continue;
}
if ("FUT_NOTICE_FIRST".equalsIgnoreCase(columnData.get(i).getName().trim())) {
futNoticeFirst = getDateValue(data.get(i), 'yyyyMMdd');
}
if ("TICKER".equalsIgnoreCase(columnData.get(i).getName().trim())) {
ticker = data.get(i);
}
if ("PARSEKYABLE_DES_SOURCE".equalsIgnoreCase(columnData.get(i).getName().trim())) {
pds = data.get(i);
}
}
return "UPDATE " + tableName + " " +
"SET FUT_NOTICE_FIRST= " + futNoticeFirst +
" WHERE TICKER='" + ticker +
"' AND PARSEKYABLE_DES_SOURCE='" + pds + "'";
}
// NEW CODE
private Date getDateValue(String sDate, String format) {
SimpleDateFormat sdf = new SimpleDateFormat(format);
try {
return
sdf.parse(format);
} catch (ParseException ignored) {
// TODO: Log this exception
return null;
}
}
i got the system time in a string for example something like "1240".
then i wanted to do something like if the system time was < than 1240,then close the application.
but it gives me the "Operator '<' cannot be applied to java.lang.String!" Error!
My code is :
runOnUiThread(new Runnable() {
public void run() {
try{
TextView txtCurrentTime= (TextView)findViewById(R.id.showtime);
Date dt = new Date();
int hours = dt.getHours();
int minutes = dt.getMinutes();
int mynum = 1240;
String curTime = hours + "" + minutes;
txtCurrentTime.setText(curTime);
if(curTime < mynum ){
System.exit(0);
}
}catch (Exception e) {}
}
});
What's the problem?
try{
SimpleDateFormat format = new SimpleDateFormat("HH:mm:ss");
String str1 = String.valueOf(hours1) + ":" + String.valueOf(minutes1) + ":" + "00";
String str2 = String.valueOf(hours2) + ":" + String.valueOf(minutes2) + ":" + "00";
Date date1 = formatter.parse(str1);
Date date2 = formatter.parse(str2);
if (date1.compareTo(date2)<0)
{
// if date2 > date1
}
}catch (ParseException e1){
e1.printStackTrace();
}
formats for dates
check date/time format as per your requirement from here
< is not defined for a string and an int of course . So you can't use it .
your current time can be calculated like this :
int curTime = 100*hours + minutes;
then you can use < between two integers.
I believe though you must use System Milliseconds which is more usual.
if(hours * 100 + minutes < mynum){
System.exit(0);
}
How can I make one data use one JSONarray? Currently I am using one JSONARRAY only. Please find code below and suggest.
public class test {
SimpleDateFormat dateFormat = new SimpleDateFormat(
"yyyy-MM-dd HH:mm:ss");
public JSONArray generateData(String idDevice, Date startTime, Date
dateTime, Date endTime) {
JSONArray arrBuff = new JSONArray();
try {
for (long i = startTime.getTime(); i <= endTime.getTime(); i += 1000) {
//for (int l=0;i<l;l++){
arrBuff.add("idDevice:\"" + idDevice + "\"");
arrBuff.add("dateTime:\"" + dateFormat.format(new Date(i)) +
"\"");
arrBuff.add("dateType: HRM");
arrBuff.add("ValueUnit:bpm");
i++;
}
System.out.println("Successfully Copied JSON Object to
File...");
System.out.println("\nJSON Object: " + arrBuff);
return arrBuff;
} catch (Exception e) {
return arrBuff;
}
}
}
I am using this code and getting the events from the calendar and it is working fine but, I want to get the events from google accounts calendar .For example, I want to get the (deepakcando90#gmail.com )google calendar accounts events also? I know it is possible but do not know how to implement it?
my code is ,
public static void readCalendarEvent(Context context) throws ParseException {
ContentResolver contentResolver = context.getContentResolver();
Calendar calendar = Calendar.getInstance();
String dtstart = "dtstart";
String dtend = "dtend";
SimpleDateFormat displayFormatter = new SimpleDateFormat("EEEE, MMMM dd, yyyy");
stime=displayFormatter.format(calendar.getTime());
SimpleDateFormat startFormatter = new SimpleDateFormat("MM/dd/yy");
String dateString = startFormatter.format(calendar.getTime());
long after = calendar.getTimeInMillis();
SimpleDateFormat formatterr = new SimpleDateFormat("hh:mm:ss MM/dd/yy");
Calendar endOfDay = Calendar.getInstance();
Date dateCCC = formatterr.parse("47:59:59 " + dateString);
endOfDay.setTime(dateCCC);
cursor = contentResolver.query(Uri.parse("content://com.android.calendar/events"), (new String[] { "calendar_id", "title", "description", "dtstart", "dtend", "eventLocation" }), "(" + dtstart + ">" + after + " and " + dtend + "<" + endOfDay.getTimeInMillis() + ")", null, "dtstart ASC");
gCalendar = new ArrayList<GoogleCalendar>();
try {
System.out.println("Count=" + cursor.getCount());
if (cursor.getCount() > 0) {
System.out.println("the control is just inside of the cursor.count loop");

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");
}
}
}

// 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?
