How To Use FormattedFields In Java For Inserting Dates
Feb 11, 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
Java Code:
package datefield;
import javax.swing.JFormattedTextField;
import javax.swing.text.DateFormatter;
[code]....

So I am working on a DB homework assignment and I am confused in how to implement a users input into the DB; I have to enter some values into a Table that is filled out by a user. It is a basic program, no GUI needed at this point.
I have written the main part but I don't know how I would get the typed value of the data into the SQL Insert Query.
Here is my code (I have a working Database and table with Java DB)
public class AddPeople
{
public static void main(String[] args)throws Exception
{
Scanner kb = new Scanner(System.in);
try
{
Connection conn = DriverManager.getConnection("jdbc:derby:PeopleDB");
[Code] .....

Compile errors. This is the code I have:
import java.util.Scanner;
import java.io.*;
public class LeapYear {
public static void main(String[] args) throws IOException {
int month1, day1, year1, month2, day2, year2;
[Code] ....
This is the compile error I'm getting:
The total number of days between the dates you entered are: 76882
Exception in thread "main" java.util.InputMismatchException

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);

I'm trying to write a program that computes the number of days between two dates. How I can achieve this. I'm quite sure I'm supposed to use the Calendar class.

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.

I need a list of all the dates in 2014 in "YYYY-MM-DD" format (because I need to load them into a database), and I do not want to type them all myself. So is there a way to actually get it generated automatically?

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?

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

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 ....

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');

having trouble trying to understand the insertion and removal of Nodes.
I have to insert a new node at the end of the linked nodes, if i insert by terminal : 1, 2, 3. The printed nodes are going to be in the same order, 1,2, 3.
I have done the exercise, but it only prints the last node created and i dont know where its the problem. We did it before with "insert at the beginning", may be the problem is with the print() method in SimpleList.java, but i dont know how to print "backwards".
This is the code:
Node.java
public class Node {
public int infoNodo;
public Node next;
}
SimpleList.java
public class SimpleList {
private Node head;
[code]....

What I'm supposed to do is make a method to insert a set of Tiles to the list,i.e.,a detour(make sure that the inserted detouris compatible with thecurrent path so that the resultingpathdoesnot have any gaps). But I'm confused on how to go about doing it. I was thinking of maybe just adding 1 to the current Node.

I need to insert a newline into a string where a letter follows a non-letter.
Example String: A63B432
I want to insert a newline after A63
I only have the string class available to me.
I'm familiar with regular expressions however I don't know how to use the String class to insert a newline.
I'm guessing the regular expression I'm looking for would be similar to:
[.0-9_][a-zA-Z]
(for . OR didgit OR underscore followed by an alpha character)
But how to insert a newline between the two?

So I'm doing a project for my CS class where we have to create a snowman doing something. My picture is of Vince Young in the 2005 Rose Bowl. I'm trying to make the actual video clip from Youtube (do I need to download it? If so I can do that) appear on the scoreboard, but how.
import java.awt.*;
import java.awt.event.*;
import java.awt.Font.*;
class snowBackground
{
public static void drawField(Graphics g, Color field)
[code]....
There are 3 other files that make the actual Snowmen.Also, would I need to download the mp3 sound file seperately and play that, or will inserting the video do both?

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

111441111i3/4/141:30 PMTuesday

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"))

I know that for a binary search tree the insert() method is easy. You just kept comparing the values of the nodes, and you would know whether to go left or right depending on the value of the node.However, I am stumped when trying to figure out how to add a node into a normal binary tree where you just keep adding the nodes to the leftmost side, regardless of value.Here is my attempt at the insert() method:
public class RegularTree extends BinaryTree {
public CompleteTree() {
super();
}
public void insert(Comparable item) {
if(this.isEmpty()) {
this.setRoot(new TreeNode(item));
return;
