write a program that reads in the year, month, and day of a couple's wedding date and compute thier next wedding anniversary after March 2, 2011.
TThis has to be input in a message dialog box also.
Here's the small project... but how can I return the value (amount) in 10 years ? The way I did, the program just doesnt return anything...
import java.util.Scanner;
public class FutureValue
{
public static void main (String []args) {
double amount = 0;
double apr = 0;
System.out.println("How much money would you like to invest?");
[Code] ....
For this program I am calculating the annual costs of 5 office supplies (user input) each with a 5.7% inflation. The user inputs the cost of each object and my program must calculate and display the price of each object each year for 5 years. I already have this part. What I need is how to add the total costs of all 5 supplies per year and display each total cost. Here is the program:
import java.util.Scanner;//Using keyboard to enter data
//Start of Class
public class OfficeSupplyCalculator {
//Start of Method
public static void main(String args[]) {
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter the first item");
[Code] .....
At the moment all I get for the grand total loop is the same number showing up 5 times. I feel like the problem is how I am declaring the grandtotalperyear variable but I'm not sure what is wrong.
i have a JTable with data that contains a column with Years.
I want to get the user to be able to sort the data between a range of two years.
Example:
a user sets te filter so he/she can view all the data between the years 1990 and 2000.
I am a beginner in Java and don't know how to code such a filter.
I guess it will be something with an if/Else statement or a loop?
so I had to make a program that prompts the user to enter a loan amount and the years for the loan and I have the conversions and everything my only issue is that when the chart pops up it just looks like a bunch of numbers and its missing the column headers
for example
Interest Rate Monthly Payment Total Payment
import java.util.Scanner;
public class InterestRate {
public static void main(String[] args) {
double monthlypayment = 0;
double totalpayment = 0;
Scanner input = new Scanner(System.in);
System.out.println("Enter Loan Amount");
[Code]...
import java.util.Scanner;
public class days
{ public EnumTest ()
{ this.day = weeks/months/years}
final int daysInMonth = 30; //constants
final int monthsInYear = 12;
final int daysInWeek = 7;
public void convert()
[Code] ....
after compiling it shows invalid method declaration ; return type required.
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

I need to write a simple program that reads an amount of minutes and displays the approximate number of years and days for the minutes. For simplicity, assume a year has 365 days and the resulting amount of days is a whole number.
View Replies View RelatedI 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 have a date sch_date_time=01/02/2014 08:00
And when i am doing SimpleDateFormat sdf = new SimpleDateFormat("dd/mm/yyyy HH:mm");
date1 = sdf.parse(sch_date_time);
when i am printing date1 it is printing as Wed Jan 01 08:00:00 IST 2014,but it should be printed as Sat Feb 01...
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.
View Replies View RelatedI 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 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 {

Apparently I can't just subtract the dates like I would in VB.
is there away to list all hours between two dates?
For example if i have 12/7/2014 21:03:56 and 12/8/2014 04:40:45 I need an output, i can write to a file: (the dates are currently in String variables)
12/7/2014 21:00
12/7/2014 22:00
12/7/2014 23:00
12/8/2014 00:00
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?
View Replies View RelatedI 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

//Program prompts user for today's day (0-6) and a number for future date.
import java.util.Scanner;

I was thinking of a second string for futureDate to print after: "the future day is " line.
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 {

boolean isTrue=false;
if(year%4==0 && year%100!=0) isTrue=true;

USING A WHILE OR A DO-WHILE LOOP write a program to compute PI using the following equation:
PI = 3 + 4/(2*3*4) - 4/(4*5*6) + 4/(6*7*8) - 4/(8*9*10) + ...
Allow the user to specify the number of terms (5 terms are shown) to use in the computation. Each time around the loop only one extra term should be added to the estimate for PI.
Alter your solution from part one so that the user is allowed to specify the precision required between 1 and 8 digits (i.e. the number of digits which are correct; e.g. to 5 digits PI is 3.14159), rather than the number of terms. The condition on the loop should be altered so that it continues until the required precision is obtained. Note that you need only submit this second version of the program (assuming you have it working).
