Swing/AWT/SWT :: JCalendar - GUI For Picking Dates

Feb 6, 2014

I am working on a school project with Jcalendar from Toeder. I am using it as gui for picking dates. Single frame with panel- Jcalendar and one textField to store the date . This date will be sent to oracle database... I have to store somehow the date of the cell that is picked. I suppose it has to be done with PropertyChangeEvent like:

JCalendar jc = new JCalendar();
jc.addPropertyChangeListener("calendar", new PropertyChangeListener() {
@Override
public void propertyChange(PropertyChangeEvent e) {
final Calendar c = (Calendar) e.getNewValue();
System.out.println(c.get(Calendar.DAY_OF_MONTH));
}
});

I looked at some examples but i didnt find a solution how to implement this event. Can I get a information where does this code goes?

How To Prevent Randomizer From Picking Same Index In Array Twice

Apr 29, 2015

import java.util.*;
public class DungeonsAndDragonsRedux {
public static void main(String[] args) {
Scanner s = new Scanner (System.in);
Scanner t = new Scanner (System.in);
t.useDelimiter("\n"); // Prevent scanner from reading code after nextLine().

[code]...

I have this program that is attempting to randomly equip the player with items that are randomly chosen from a list. I don't know how to prevent it from picking the same item twice though. I also don't know how to display the items that haven't been equipped, which is another requirement of this program.

How To Calculate Difference Between Two Dates

Oct 19, 2014

I have been tasked with creating an invoice (school assignment). Part of the calculations is creating an interest depending on the amount of days between the current date entered, and invoice date entered (The program prompts the user to enter both the current and invoice dates by asking for the day, month and year).

We are also supposed to set the contructor to a default date of 1/1/1900.. but I don't know how or where to code that.

How to calculate the difference between the CurrentDate and Invoice. I have displayed the dates to the user as follows.

public void displayDate() {
System.out.println("
Today's Date: " + month + "/" + day + "/" + year);
}
public void displayInvDate() {
System.out.println("
Invoice Date: " + invMonth + "/" + invDay + "/" + invYear);

How To Use FormattedFields For Inserting Dates

Feb 10, 2014

I know the below code is supposed to format the FormattedTextField but it doesn't seem to do anything to the form (shown in the picture below). I was wanting, when the form loaded: the text field to look something like this

00/00/2014 - 00:00 am

Where the user is able to

- enter datelike information around the symbol separators ( / or : )

- But where the user could not remove these symbol separators

Code:

package datefield;
import javax.swing.JFormattedTextField;
import javax.swing.text.DateFormatter;
public class NewJFrame extends javax.swing.JFrame {
public NewJFrame() {
initComponents();

Difference In Days Between Dates

Dec 5, 2013

I know this has been covered before but none of the answers made sense to me. I'm hoping there is an easy way to do this. I have 2 user inputted strings that I have converted to dates and I just want the difference in days.

My code :

import java.util.Date;
import java.text.SimpleDateFormat;
import java.util.Scanner;
import java.text.ParseException;
public class DateTest {
/**
* @param args the command line arguments
*/
public static void main(String[] args) throws ParseException {

[Code] ....

Apparently I can't just subtract the dates like I would in VB.

Working With Gregorian Dates And Object Date?

Feb 10, 2014

I have two classes - a reservation class & a main class. Essentially, I want the user to enter two dates: an arrival and departure date. From the two dates, I will do a calculation (num days & price). I am having trouble finding a way to let users enter the (preferably in int, but that wasnt working),use getTime() to convert it from a calender to a date object. Then I want to use the dates to do a calculation. In addition, my constructor is being funky.

package hotelreservation;

import java.util.Calendar;
import java.math.*;
//import java.text.*;
public class Reservation

How To Write A Program To Record Names And Dates

Mar 2, 2014

I want an app that I can use to save the name, address, item sold, subject discussed and date that I visited someone - in a job similar to a sales rep. I would like to be able to choose how to sort the info so that if I sort by date I can see who hasn't been visited for the longest and start there. If I think of someone's name then of course I want to sort by name.

One of my friends says he works with "php"[? I'm still learning these terms] and everything happens online. I would like it to be an android app so it can be done without an internet connection ....

Sorting Dates - Saving Result In Class

May 18, 2014

So, I have two classes (bubble sort and insert sort) which are sorting dates. I need to save their comparings and reallocation of elements.

And I don't know how to do it. The point is if I want save that dates(comparings and reallocation) to Result class i need to create new instances of class in each sorting classes so i can't later do something with that, because I have null in Main class.

To avoid that problem i have tried to make Result class as singleton.. I mean: "public static final Results INSTANCE = new Results();" and then in classes "static Results result = Results.INSTANCE" without constructor and to save for example comparings i had method:

Java Code:

int SetComparings(){
return comparings++;
} mh_sh_highlight_all('java');

But it do not work too, because it overwrites old dates. Is there anyway to do not create instance of class? I don't want to copy whole code because it is too long and cant be unreadable, but i will put you structure of my program:

Java Code:

class BubbleSort{}
class InsertSort{}
class Results{}
class Sorting{} // class with switch to choose which way of sorting use
public class Main{} mh_sh_highlight_all('java');

Report Employee Time Clock Cannot Find Corresponding Dates In And Out

Mar 8, 2014

I have this assignment to build an employee time clock. By using a menu you can enter an employee, enter punch in and out, and report.When I created the punch screen I wrote the in and out records to a file. Because there can be several employees punching in or out the file wrote each occurrence on different lines. Now I am attempting to write the report which you enter an employee Id and loop through the file to find the in and out date and then calculate the time (hours worked). I loaded the file into an Arraylist but now I cannot figure out how to loop through find the In and Out date - calculate the hours worked and then move on to the next day. here is the format of the file - employee id, place holder I or O, date, time, day. and sample

111221111i3/2/145:10 PMSunday
111221111o3/2/145:10 PMSunday
111331111i3/2/145:25 PMSunday
111331111o3/3/1412:47 PMMonday
111221111i3/3/1412:48 PMMonday
111221111o3/3/142:23 PMMonday
111441111i3/4/141:30 PMTuesday

[code]....

here is my code from the main screen.

public static void displayPunches()
throws FileNotFoundException, IOException, ParseException {
boolean isValid = false;
String choice = "y";
String emp = Validator.getLine(sc, "Enter I -Individual or A -All ");
if (emp.equalsIgnoreCase("A"))

Swing/AWT/SWT :: Add Progressbar To Project For Listening Swing Worker Updates?

Feb 16, 2014

I have a problem with progress bar implementation to my project. Let me explain it;

I have Jframe named GUI. Filled with 2 datechooser combo box and 1 Buton.

And i have a Swingworker class named "MySwingWorker" for my long running task just like this;

package exampleproject;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.Level;
import java.util.logging.Logger;

[code]....

Just i want add a progress bar for listening MySwingWorker's setProgress updates. When buton clicked swingworker should executed and progress bar should come to screen. I read many articles about that but not understand correctly. Because i am beginner in JAVA.

Question1: Should i (create new class) or (implement to current gui or swingworker class) for progressbar?

Question2: Should i fired progress bar first and execute swingworker from progressbar class? or should i execute swingworker first and fired progress bar later and how?

Swing/AWT/SWT :: Factory Design Pattern With Swing JDialog

Jul 26, 2014

Is it a good idea to use the factory design pattern for say if I needed to create four different JDialogs for the same parent frame?

factory design interface
package client;
public interface Dialog {
void getInstanceOf ();
void initComponents ();
}

One of the four JDialog class would look something like this without the comments.

package client;
import javax.swing.JDialog;
@SuppressWarnings("serial")
public class AddCustomerDialog extends JDialog implements Dialog{
public AddCustomerDialog () {
//Some stuff goes here to set the settings for JDialog instance

[code]....

Of course you would have your factory class
