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'm a Java beginner and I'm having issues implementing Java's GregorianCalendar into my project. I'm writing to specific test code that passes arguments into an instantiated GregCal class. My problem is that I'm not sure how to pass the arguments through to my constructors and methods, or if I'm even supposed to do that at all. Date formatting is another issue, but I'll be glad If I can just get the dates in and back out. Here is some of the code:
Test code: // Create a Student using the default constructor Student newStudent = new Student(); GregorianCalendar dateOfBirth = new GregorianCalendar(75,7, 3); newStudent.setDateOfBirth(dateOfBirth); GregorianCalendar dateOfGraduation = new GregorianCalendar(90, 6, 10); newStudent.setDateOfGraduation(dateOfGraduation);
Setter: public void setDateOfBirth (GregorianCalendar dateOfBirth){ this.dateOfBirth = dateOfBirth; }
I know that's not much to work with, but that's exactly my issue. I can't seem to find a reliable and UNDERSTANDABLE tutorial for java.util.GregorianCalendar anywhere. All of the existing documentation is beyond my grasp at this point. I'm assuming I need to declare and initialize MONTH, DAY, YEAR variables somewhere in order for the arguments to be passed through correctly. I'm just not sure where or how.
I am having a hard time getting some comparisons with Date to function correctly.I have a driver program and two classes, ZodiacDriver , ZodiacSign and ZodiacTable. In the driver program I build an arraylist of zodiacsigns in zodiactable. That all appears to be working I then pass a birthdate and the zodiac table to a method, determineSign. This is where I am having trouble. Right now Im just trying to match the incoming birthdate with a zodiac's date in the table. however no matter what date I enter, i get pisces, which happens to be at the bottom of the list. If I remove pisces from the list I get the current last zodiac. Here is my code:
When trying to convert the time zone of a date I encountered the log below. java.lang.IllegalArgumentException: Cannot format given Object as a Date..Here is what my code looks like:
1. First I will get the date from the email header by the following code.
I am looking to get the sublist from a list of objects as per date enter. Objects that are added in the list (partyList) has the property of type Date. Below is my method, but not able to figure it out, how can i get the sublist.
public void listAllPartiesDayWise() { System.out.println(" Inside List All Parties - Date Wise"); System.out.println(" Enter the time for the party in format yyyy-MM-dd HH:mm "); List<RegisterParty> partyListDateWise = new ArrayList<>(); Scanner scanner = new Scanner(System.in); String date = scanner.nextLine();
I am converting String to date object while converting this i am getting Run time Exception. Here in this code i am using String tokennizer reading a data from a text file. Here is my code
public static void main(String[] args)throws Exception { FileReader fr = new FileReader("g:abc.txt"); BufferedReader br = new BufferedReader(fr); String line = br.readLine();
I have a date in the following String format "2013-03-28,19:37:52.00+00:00" and post processing I am converting this to following String as per prevailing logic "2013-03-28,19:37:52.00+0000" (This is existing code and no changes have been Made here for last few years) And the using this SDFormat i.e new SimpleDateFormat("yyyy-MM-dd,HH:mm:ss.Sz") for conversion to Date Object
We are suddenly getting this exception now can't figured out what has changed ?
java.text.ParseException: Unparseable date: "2013-03-28,19:37:52.00+0000" at java.text.DateFormat.parse(DateFormat.java:357)
I am having trouble with getting output to be what I want. I can get the output when a user enters their values for month, day and time using a scanner object and they print correctly, but what I want is before they input values, to display the current date. Here is a snippet of what I am working with *these are in two separate files, the first has all the variables etc, the second has the main method.
In one java file:
Java Code:
private int numOfGuests, month, day, year; private GregorianCalendar eventDate = new GregorianCalendar(); public Event() { this("not assigned" , 0, new GregorianCalendar()); } public int getDay() {
[Code] ....
This gives me 0-0-0 as a result instead of current date.
Here is my code the whole program is working correctly but the Boolean equals and the has code and it is a requirement for the assignment. Why it is not working.
I know there are issues with the code I am new with java and was struggling so I have to clean my code up before I submit the assignment but for right now I have the out put the way I want it except the Boolean and hash code methods always output that the rectangles aren't equal even when I know they are and it outputs the not equal statement twice??
I have an requirement of splitting a Date-Time String i.e. 2013/07/26 07:05:36 As you observe the above string has Date and Time with space in between them.
Now I want just want split the string not by delimiter but by length i.e. after 10th place and then assign it to 2 variable i.e. Date <----2013/07/26 and Time <---07:05:36 separately.
1. Write an algorithm that asks the user for your birth date and the current date and displays how many days has passed since then (remember that April, June, September and November has 30 days, February has 29 on leap years, and the rest 31)
2. Write an algorithm that asks the user a number (save it as N) and displays the N term of the Fibonnacci series (take it as 1, 1, 2, 3, 5 ...)
Given a Date such as this sampleDate (120, 08, 02), does SimpleDateFormat transform this given sampleDate using (sampleDate.get(Calendar.DATE)) ?
Issue is that without the SimpleDateFormat the days are outputting correctly but starting with 1,2,3,4 etc and when I apply the SimpleDateFormat to the above Date I only get 01,01,01 etc...
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 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'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 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.
