Thread: library or component for Hijra date chooser

Interesting problem. I have never stayed up that late at night for testing a java program.

Unlike you, I always work at night and sleep during the day. I am always talking to you from 10 pm to 3:45 am.
Because I concentrate better in silence now here is 2:02 AM
The interesting thing is that this problem is reset every week and each number is put in its place, and with each passing day, the number of numbers increases again. and If we turn the calendar back, it goes back one step at a time

--- Update ---

WHAT IS MEAN

Calendar cal = getCalendar();
 cal.get(Calendar.DAY_OF_WEEK)
cal.set(Calendar.DAY_OF_MONTH, 1);

  Calendar cal = getCalendar();          // get an instance of the Calendar into cal
  int dayOfWeek = cal.get(Calendar.DAY_OF_WEEK);  // get day of week for cal object
  cal.set(Calendar.DAY_OF_MONTH, 1);     // set the day of the cal object to first day of month

Sorry, I don't know what the problem is. Can you explain in more detail and give an example?

when use hijridate class as component in other form i see a hijri date chooser some times i need set a date in the hijri date chooser text like when i load date from database and when use hijri.settext() or hijri.setdate() it is dont't happened and i see this error for set text( hijri.setText("1442/09/21") )

method setText in class HijrahextendsJPanel cannot be applied to given types;
  required: no arguments
  found: String
  reason: actual and formal argument lists differ in length

and this for set date

method setDate in class HijrahextendsJPanel cannot be applied to given types;
  required: no arguments
  found: Date
  reason: actual and formal argument lists differ in length

and when use set method in the form create this in hijri class

void setText(String string) {
        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

now i don't know what i must write there

--- Update ---

this is my all class code

package GHDate;

--- Update ---

i think i must use datetext.setText(); but how?

i see this error for set text( hijri.setText("1442/09/21") )
method setText in class HijrahextendsJPanel cannot be applied to given types;
required: no arguments
found: String
reason: actual and formal argument lists differ in length

That error says the setText method is declared to have no arguments, but the calling call tried to pass it a String.
If you want to pass a String to the setText method it needs to be defined to take a String as its argument.

now i don't know what i must write there

Why are you calling the method if you don't know what it is supposed to do?

use datetext.setText(); but how?

Put that code inside of the setText method.

Did that work?

What is getText supposed to return? Where is the data that can be used to create the desired value to return?

Any text written inside the text box is of date type like 1442/10/21
and getDate print hijri year and Gregorian month and day

--- Update ---

System.out.println(hijrahextendsJPanel1.getDate());

--- Update ---

Sat Sep 22 00:00:00 IRST 1442

--- Update ---

and always show time 00:00:00

--- Update ---

and always show current hijri year

text written inside the text box

Look at how the setText method worked. Copy that idea for getText.

A get method normally does not pass any arguments. It returns a value - it is not declared as void.

What should getText return? Where is the value to be returned?

Yes, that looks like it pairs with the setText method.
The extra call: datetext.getText(); is not needed.

What data type/class is the getDate method supposed to return?

hijridate

--- Update ---


DEFAULT_DATE_FORMAT = "yyyy/MM/dd"
something like this

String getHDateString() {                  //  ADDED
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern(DEFAULT_DATE_FORMAT);
        HijrahDate today = HijrahChronology.INSTANCE.date(ye, mo, da);
        String formatted = formatter.format(today); // 1442/10/20
 
        return formatted.toString(); //<<<<<< ADDED
    }

--- Update ---

or like this

public void hdate() {
        HijrahDate hijrahDate = HijrahDate.now();
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern(DEFAULT_DATE_FORMAT);
        formatted = formatter.format(hijrahDate);   // 1442/10/20
        ye = Integer.parseInt(formatted.substring(0, 4));
        mo = Integer.parseInt(formatted.substring(5, 7));
        da = Integer.parseInt(formatted.substring(8, 10));
    }

Is this the class: HijrahDate
Spelling is important. hijridate is not the class name.

Look at the constructor for the HijrahDate class and see how to build an instance of that class with the desired values.

What is the problem with that code?
What values are supposed to be in the HijrahDate object that is returned?
How can the object with those values be created?
Look at the API doc for the class.

like this

public Date getDate() {

I thought the getDate method was supposed to return a HijrahDate object, not a Date object.

how fix getDate?

Is this the problem you are working on now?

yes and i think after that just i have one problem and finish this god damn project

--- Update ---

It took me a lot of time and energy to get a free component and publish it and make it available to the public

--- Update ---

i think this part must change

private SimpleDateFormat dateFormat;
private SimpleDateFormat getDefaultDateFormat() {
        if (dateFormat == null) {
 
            dateFormat = new SimpleDateFormat(DEFAULT_DATE_FORMAT);//DEFAULT_DATE_FORMAT = "yyyy/MM/dd"
        }
        return dateFormat;
    }

for fix this part

public HijrahDate getDate() {
            try {
            return getDefaultDateFormat().parse(formatted);// here not working (incompatible types: Date cannot be converted to HijrahDate)
            }catch (ParseException e) {
            return HijrahDate.now();//i don't must use this code because don't get text date always show just today date
            }
    }

HijrahDate getDate() replace this part

public Date getDate() {
        try {
            return getDefaultDateFormat().parse(formatted);
        } catch (ParseException e) {
            return new Date();
        }
    }

for hijri date format we use this code

        HijrahDate hijrahDate = HijrahDate.now();
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern(DEFAULT_DATE_FORMAT);//DEFAULT_DATE_FORMAT = "yyyy/MM/dd"
        formatted = formatter.format(hijrahDate); // 1442/10/14
