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.
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 to create a simple Java program that calculates the difference between two entered days of the week with the following requirements:
-Ask the user to enter in a day of the week by name (e.g. Monday) - Ask the user to enter in another day of the week by name (e.g. Friday) - Create a static method other than main that takes in two Strings as input, and returns an integer value equal to the difference between the two days - Use an array with the days of the week in it to find each entered in day of the week, and use their indices to calculate the difference - Output the difference for the user to see
I have to use methods and loops to code this program. Cannot use any java set or any built in java shortcuts!
import java.util.Scanner; public class setPractice { public static Scanner kbd; public static final int MAXSIZE = 20; public static void main(String[] args) { kbd = new Scanner(System.in);
[Code] .....
This is the input I put in my code and this is the output:
How many numbers will be in the 1st set: 3
Enter list of integers for 1st set: 34 2 56
The ascending order for 1st is: 2 34 56
How many numbers will be in the 2nd set: 4
Enter list of integers for 2nd set: 56 2 33 6
The ascending order for the 2nd set is: 2 6 33 56
The intersection of the two sets is: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
As part of the instructions we are required to use loops and methods to solve to program this code. We are not allowed to use any set functions that are already built in java.The methods for intersection and difference MUST return int value.
import java.util.Scanner; public class setPractice { public static Scanner kbd; public static final int MAXSIZE = 20; public static void main(String[] args) { kbd = new Scanner(System.in);
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 at java.util.Scanner.throwFor(Scanner.java:909) at java.util.Scanner.next(Scanner.java:1530) at java.util.Scanner.nextInt(Scanner.java:2160) at java.util.Scanner.nextInt(Scanner.java:2119) at LeapYear.main(LeapYear.java:16)
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 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();
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 need to find out if two dates are equal or not. I have two dates coming from UI and from DB. From UI I am getting as Sun Jun 15 00:00:00 CDT 2014 from DB I am getting as 2014-06-15 00:00:00.0. Data type for both fields are java.util.Date but when I do uiDate.equals(dbDate) it return false. So how can I test these dates to fins out they are equal or not?
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');
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
How to get used to program control statements. This is an attempt to write a program that returns the number of days between two dates. Sadly, it give incorrect values.
public class DaysBetweenDates { public static boolean isLeapyear(int year) {//This method will determine if a year is a leap year or not boolean isTrue=false; if(year%4==0 && year%100!=0) isTrue=true; else if(year%400==0) isTrue=true; return isTrue;
In the class below I'm trying to create a class that will accept dates in various formats and create a range. The first constructor is easy because I send it the begin date and end date as Date objects. Now I want to send a month(and year) in a constructor and derive the begin and end dates from it. In my constructor that accepts the month/year I need to put the this(startDate, endDate) at the top to be allowed, but the parameters are not built yet.
package com.scg.athrowaway; import java.util.Calendar; import java.util.Date; public class DateRange { private Date startDate; private Date endDate;
I am new to java i dont understand the difference between the abstract and inheritance i mean we use the abstract class with extends with other class name ,even we do that same in the inheritance pls tell me main difference between abstract and inheritance...
