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.
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.
The LocalStudent class inherits the Student class. The IDE states an error of "no default constructor in Student class".I understand that if a LocalStudent object is created, the default constructor of its superclass (aka Student class) will be called implicitly.there is no LocalStudent object being created, so why is the default constructor of Student being called ?
The default constructor of LocalStudent is also overloaded by the created no-arg constructor containining subjects = null; . So there is no call to the superclass default constructor from the default constructor of LocalStudent.
public class Student { private char year1; public Student(String name, char year){ year1 = year; } public char getYear(){ return year1;
I am writing a program that accepts input from the user, I want default values displayed before the input values.
Java Code:
public surfboards() { surfboardType = "Type not assigned"; shaperName = "Shaper not assigned"; constructionType = "Construction Type not assigned"; surboardSize = 0D; } mh_sh_highlight_all('java');
I can get the output to display as shown below
(THIS IS WHERE I WANT DEFAULT CONSTRUCTOR DISPLAYED. Currently not displayed)
Type not assigned Shaper not assigned Construction Type not assigned 0 Feet
(THIS IS WHERE I WANT DEFAULT CONSTRUCTOR DISPLAYED. Currently not displayed)
input:
Java Code: Enter Surboard Type: test Enter Shaper Name: test Enter Surfboard Construction Medium: test Enter Surfboard Size: 6.5 mh_sh_highlight_all('java');
How do you test a default constructor in one class and then test it in a different class? This is the code for the Person class which has the default constructor. I'm not sure in the PersonTester class how to access this default constructor and how to test it - what I have so far for the second class is also below.
class Person { // Data Members private String name; // The name of this person private int age; // The age of this person private char gender; // The gender of this person
In the following code the print method prints the default value of int(zero) for the first time even when the variable i has been assigned a value of 4. Why?
class A1{ A1() { System.out.println("Inside constructor of A1()"); print(); } void print() { System.out.println("A");
[Code] ....
Output: Inside constructor of A1() 0 Inside constructor of B1() 4
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 would like to set a specific time for a Calendar instance. My below code will set a time one minute ahead of the current time, and format it to ISO8601 standard.
I now want to set another variable(deadlineDate), but to a specific time, say 5 minutes ahead. I would like to hardcode this in so I dont want it to change as a result of getting the instance of the Calendar(which sets it to the current time)
Essentially I am trying to regenerate the above code every minute and increment itself each cycle until it reaches the deadlineDate, which is a fixed datetime.
import java.util.Calendar; import java.util.GregorianCalendar; public class CalendarCalc { public CalendarCalc (){} private static void printCalendarMonthYear (int month, int year)
[Code] .....
IDE is telling me this:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The method printCalendarMonthYear(int, int) is undefined for the type CalendarDisplay
at CalendarDisplay.main(CalendarDisplay.java:46)
Btw, I have a main class. This is just the class responsible for doing calculations.
I'm having an issue with this little bit of conversion. I'm converting a string (_dateString) into a Calendar time. I am using DateFormat and SimpleDateFormat to accomplish this task. Everything seems to be working great, except for it figuring out whether it is AM or PM. According to SimpleDateFormat (Java Platform SE 7 ) I am using "aa" to get my AM or PM marker. How come in my output then, it believes it to be 4:45 am instead of 4:45 pm? Hour of Day should return the 24 hour clock, which should show 16 instead of 4. I have posted the output below my code.
Java Code:
import java.text.*; import java.util.*; public class Time{ static String _dateString = "08 Feb 2014, 4:45pm"; public static void main(String args[]){ Calendar cal=Calendar.getInstance();
[Code] ....
Output:
Java Code:
Today is Sat Feb 08 04:45:00 EST 2014 Year: 2014 Month: 1 Day of Month: 8 Day of Week: 7 Week Of Year: 6 Week of Month: 2 Hour: 4 Hour of Day: 4 Minute: 45 Second: 0 Millisecond: 0 mh_sh_highlight_all('java');
i have a problem, i need build a calender in BlueJ. The program need to found if I put this one year have to give me the full schedule but only the first semester.
I am currently using notepad to create a Java program and using the command box to compile it and execute it and it has been working fine. I have the JDK version 7 so java.lang works which I know does not need to be imported. The Calendar method which should be recognized is not.
Here is the program. Cut this program and compile it in the command box. It will not recognize the Calendar method.
import java.util.*; class Practice4_2 { public static void main (String args[]) { Calendar cal = Calender.getInstance(); Date.now = new Date();
I created a calendar program so when the user enters a day number and a year it would show the calendar for the year . My issue was that I could not get the numbers to line up neatly and how they should look . Also if its not to much trouble I would like to know how to turn this in to a loop .
import java.util.Scanner; public class Calendar { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.println("Enter a Year"); int Year = scanner.nextInt();
I'm working on a program that prompts the user to enter the year and first day of the year and displays the calendar table for that year on the console. For example, if the user entered the year 2005, and 6 for Saturday, Juanuary,1, 2005, the program should then display the calendar for each month of the year.
I have written the program and solved the problem for the most part. Only, I'm having terrific difficulty getting the output to properly format. I'm *almost* there. I'll post my program below and then output.
import java.util.Scanner; public class DisplayCalendar { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("Enter the year: "); int year = scanner.nextInt();
I am working on an application using JSP and SERVLET.
Somewhere I need to show the reminders on a particular date on calendar (Jsp page). I have used javascript for calendar and entering reminder from another UI. So I need to display an image on the calendar date which is matching with reminder date. The problem is how can I display the image on that date which is on calendar.
I have a problem to display a popup with the information of the registered event. I would like the user to hover over a particular event exhibited only the description of the event without having to click on the event to view information. I would like to make an ajax request to that was displayed a popup.
But do not know how to implement jquery and javascript. Well, I am new to programming. My code that generates the schedule is as follows:
In my Bean have methods that make the selection of date and event. Have I configured the option of setEditable to true. Ajax function, jquery or javascript to show the popup containing only observation and event date. And looked at the documentation of primefaces and not found any implementation to solve my problem.
I am writing a short program to find the zodiac of a given birth date. I am checking to see if a calendar object falls between to other objects to see if the date falls within a certain zodiac sign. To accomplish this, I have the user enter a date, then that date is compared to dates taken from an array. The problem is sometimes the comparison doesnt seem to work work, giving the wrong zodiac. For example if I enter 03/28/1968, it finds Aries, as expected. However if I enter 03/20/1968, it returns Aries also, when it should return Pisces. Here is the sample code.
private static String determineSign(Date birthdate, String[][] zodiac) throws ParseException { // TODO Auto-generated method stub Date date = birthdate; for (int row = 0; row < zodiac.length; row++) { DateFormat date3 = new SimpleDateFormat("MM/dd"); Calendar compDate3 = Calendar.getInstance();
[Code] .....
This is the class that creates the table used for the zodiac dates -
public class ZodiacTable { static final int ROWS = 12; static final int COLUMNS = 3; //private ArrayList<String> zodiacNames; private String[][] zodiacNames;
[Code] ....
I cant seem to see why it returns the wrong zodiac..
I have a PrimeFaces page with a calendar component on it. Radio buttons on that page work fine and call the setter method on the back end. The Calendar however doesn't call the setter. The getter method is called on page display.I'm using the PrimeFaces v 5.0 jar file.
I need to add a few days to make an end date (for instance the start date is the first date selected, and then the end date is x amount of days after that... I think I should be using the add() method but I am not quite sure of where or how to do so)...
Java Code:
//Get an instance of Calendar and DateFormat class, and get current date from the system using OnClick method Calendar startVacation = Calendar.getInstance(); DateFormat fmtDate = DateFormat.getDateInstance(); DatePickerDialog.OnDateSetListener startVaca = new DatePickerDialog.OnDateSetListener() {
Every year, she has to plan when her employee's can go on vacation for the summer holidays - MANUALLY. It takes weeks to solve the puzzle, because she has several kinds of employee's hired, with different skills. And at all days there must be X amount of employees with skill1 at work, plus Y amount of employees with skill2 etc, and they also need special "off-days" in comparison to when they last worked and so on. It's quite the math puzzle.
I've worked a little with C#, and built a prototype of a Support System (Ticket based), so I got the basics down of programming, and I know Java and C# are quite alike, so I don't think making the switch will bother me that much.
The program should be easy to use for her, so it needs a visual calender that can be interacted with, and it should also be easy to see which employee is at work at that date and so on.
Will it be hard for me to build this kind of Calender, that allows the interaction I want?
Any open-sourced projects, or libraries that will make my task easier?
