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 have code that displays 3 game scores the series total and average. For some reason game 3 outputs 0 and game 1 and 2 output correctly. I don't see anything different that game 3 is doing that game 1 and game 2 aren't so I'm not sure what the problem is.
java file
package com.valenciaprogrammers.mybowlingscores; import java.text.DateFormat; import java.util.ArrayList; import java.util.Collections; import java.util.Date; public class BowlingScores implements Comparable<BowlingScores>{ private long id;
I have a loop and I was wondering why it is outputting my line twice. Here is the code:
while (x != -1) // closes the program if the user enters -1 for x { System.out.println("Which jar would you like to access? Please select a number between 1 and 3. Press -1 to exit."); x = scan.nextInt(); ourpantry.Selection(x); // tells our pantry class what number the user selected while ((response != "continue")) // loop continues until user gives a valid response
[Code] ....
This results in the Output:
Would you like to spread jam? Y or N. Would you like to spread jam? Y or N.
My current assignment involves me outputting these 2 classes. Yet I'm not really sure in what manner I should go about doing this. I have tried creating a separate class and outputting my toString methods there but for some reason I am getting an error. .
The error message is thus;
Exception in thread "main" java.lang.NullPointerException at Vehicle.toString(Vehicle.java:91) at Run.main(Run.java:17) Process completed.
I am currently working towards taking input from the user and storing it in an excel document. However how can I test to make sure that I am trying to save it to an empty cell. Is there some type of method that will check to make sure the cell is empty, otherwise how can this be done?
I was struggling to use BufferedReader to extract some data and then perform some calculations and then have the results as outputs.
I haven't quite solved that issue but in order to progress, I hard coded some values into my application and proceeded with the actual calculation loops etc.
Currently, the value out put from one of my calculations is given as:
1.1704926E7
How can I make the console show it in a natural way. I've performed the calculation manually and it should be 11704926.5 I don't want to lose that .5!
Ideally, it's suppose to print out only Test2, Test3, Test6.. I've tried different combinations of loops and equals() but I never get the correct output.
This is sort of like the last problem I had but it's all about the formatting at the end. I have a file that reads something like:
Name a bunch of text here and perhaps a second or even a third line
I need to output this as:
Name; "a bunch of text here and perhaps a second or even a third line"
Right now I find 'Name' and it outputs:
Namea bunch of text here and perhaps a second or even a third line
How would I add ";" and quotes in the middle? I can imagine that I may need to find name, then skip to the next line and just add name manually as the variable output of the search string.
This is where I am now
public static void main(String[] args) { boolean output=false; String name=""; String junk="CHAMBERS"; TextIO.putln("Search for a name"); name = TextIO.getln(); TextIO.readFile("doc.txt");
[Code] .....
So I'm almost there, but those dange double Names are killing me. I tried to add a bit of code where:
I am Having trouble with my program to validate. It is outputting null into the validation statement then it brings back a run-time error to that validation Statement for the String.
public String validateData () { if (nm == null)nm = "Error! Must enter at least one character"; else nm = name; return name; }//end validation method
Why is this happening, and then once that is completed, why is the validation Sentence in tests Scores not able to validate. I traced it back to out put "Error, a number between 1<100".
public void validateTests () { String testschange; if (test1 < 0 || test1 > 100) { testschange = " You have entered an invalid number, between 1-100. Please restart!"; testschange = Integer.toString( test1 ) ;
At the moment I am studying it and the problem is Taking a range of names in an array and outputting them alphabetically, But for some reason I get an outOfBoundsException. And its starting to get to me. How to put the code in
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'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.
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.
