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 am writing a program in the GUI Builder and found that when I add code to print user input from text fields to a text file, the main method is no longer recognized. It throws all kinds of errors.
I have been able to get the code to work separately in a project file. Also, have been able to print to the console.
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.

Detect a bug in Java, specifically in the Calendar class will getDisplayName method. I put in the message code showing the error. If the code is executed you can see that the month March be repeated 2 times jumping the month of February.
Code Example:
import java.util.Calendar; import java.util.Locale; public class BugInCalendarDisplayName { public static void main(String[] args) { Calendar aMonth = Calendar.getInstance(); aMonth.set(Calendar.MONTH, 0);
[Code] ....

Which version of Bouncy Castle and JDK version this supports?
This code doesn't recognise the package ( and therefore class ) timetest3, when I try to import it. The package I try to reference/call, follows, and works fine.
import javax.swing.JOptionPane; import timetest3.TimeTest3; public class timetest4 { public static void main(String args[]) { TimeTest3 time = new TimeTest3(); time.setTime(13,45,52);
The compiler tells me that the variable after the while is not recognized.
What I especially don't understand is that the variable is defined and accepted in the character input and the swicth but later on is not recognized. I'm sure of this because I wrote the entire program, and then compiled it afterwards. I was therefore able to see the compiler advancing as the code was corrected
The error message is "cannot find symbol - variable choix"
I wanted to create a simple window with the LWJGL and a key input request which closes the window.I also wanted to create the classes in seperated packages, so it's more organized.The window displays but if I press that certain key nothing happens.Here is the Main class:
package bb.main; import bb.input.Input; import bb.main.render.SimpleRenderer; public class Main { public static void main(String[] args){ SimpleRenderer createWindow = new SimpleRenderer(); Inputinput= new Input();
I have a program in which I am prompting users for integer values to display in a JFrame. I call the method below to load an array with their input:
Java Code:
public String inputAssembly(){ if (!jtfInput.getText().matches("d")){ JOptionPane.showMessageDialog(null, "Input must be of integer value."); } if (jrbFar.isSelected()){ return jtfInput.getText() + jrbFar.getText();
[Code] ....
Regardless of the input, both messages display (invalid input / got it). I've tried debugging so I know that the values are getting entered and read correct, at least to my knowledge. It is a very simple regular expression, only checking to be sure an integer was entered.
I've installed the Java JDK onto my Windows 8 laptop and the first thing I need to do is run the compiler from the Command Prompt. The first prompt I enter is C:java -version. This worked fine, however when I try to enter the next prompt C:javac -version, I am getting the following screen and messages:
Microsoft Windows [Version 6.3.9600] (c) 2013 Microsoft Corporation. All rights reserved.
C:UsersMary>java -version java version "1.8.0_20"
Java(TM) SE Runtime Environment (build 1.8.0_20-b26) Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)
C:UsersMary>javac -version 'javac' is not recognized as an internal or external command,
operable program or batch file.
I have entered the path into the environment variables area within my control panel. Not too sure why the first prompt works, but the second doesn't...
I think this might be the reason as this comboBox is not recognized at the import to the scene builder library. I can show up the import dialog of custom controls, but my custom ComboBox is not showing up. All other implementations are there correctly as they are loaded from my customControl.jar file
I use the ComboBoxListViewSkin for the functionality to scroll to an item in the combo as a user types a letter on the keyboard.
I do this by:
/** * This method scrolls the itemView of the items to the first item starting * with the given char or string * * @param pressedKey */ public void scrollToChar(String pressedKey) { String value = pressedKey.toUpperCase(); for (Object userEntry : getItems()) {
[Code] ....
I really need to show up my custom Combo in the scenebuilder, as otherwise the rest of my fxml is not editable in sceneBuilder 2.0 ....
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 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 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.
