I'm doing a problem where I convert users input for the date (MM/DD/YY) into a written out date and year. That part is fine. The part I'm struggling with is then indicating what day that is in that year. how to use the user inputted MONTH, DAY, and YEAR to then get the day of year.

I Have been playing with this for while, and I can not seem to get my head around, how I can do this. I need to get the last two digits of a year that a user will enter. For example, a date like July 2 , 2014, I want to get the last two digits of year 2014 which are "14" and divide it by 4. This will give me 3.5; how ever I will disregard the ".5" and just keep the 14. I have no problem doing the division, my biggest this is how to just get the last two digits of a year. This is what I have so far, it is basically a template of how I want my program; I just need getting the last 2 digits of a year.
public class DateCalc
{
public static void main (String[] args)
{
String month;
int day;
int year;
[Code] ....
" This will give me 3.5; how ever I will disregard the ".5" and just keep the 14 ". I meant that I just want to keep the 3 from the 3.5 that will be generated when you divide 14 by 4.
I want to limit the program to only accept a 12 digit input and an integer value but I don't know how to program it,

Score Letter Grade
90-100 A
80-89 B
70-79 C
60-69 D
Below 60 F
double test1,test2,test3,test4,test5;

figuring out the logic to print the day number of the year. The directions for my homework are: Write a program that prints the day number of the year, given the date is in the form: month day year. For example, if the input is 1 1 05, the day number is 1; if the input is 12 25 05, the day number is 359. The program should check for a leap year . I have a basic outline of the program but i am having trouble with figuring out the logic to display the day number of the year given the date. This is what i have so far

I am doing an assignment for my class and I wish to know if there is anything I did wrong or what would make it easier to read, the assignment is to make a program to check if a year (the user provides the year) is a leap year.

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 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?
View Replies View RelatedThis assignment uses the following description to implement a Dialog class for the Leap Year Problem. We need to decompose this problem into 2 classes:
1.The Date.java class: is a public class that represents a date composed of a month , day, and a year. So you need to declare month, day, and year as integers. Date has 1 constructor and 4 methods. Write the constructor for Date which has 3 parameters: int m, int d, int y ; (As an example of a constructor with 2 parameters for example chapter 3 page 152 code listing 3-13 has a perfect example for you to use which is the BankAccount.java.) and the 4 methods:
"dayIs()" which returns a day. It has no parameter.
"monthIs()" which returns a month. It has no parameter.
"yearIs()" which returns a year. It has not parameter.
"isLeapYear()" which returns a boolean value.
"isLeapYear()" has one parameter year and returns a boolean. Write the method isLeapYear() knowing that a year is defined to be a leapyear it is a multiple of 4, and if it is is a multiple of 100, it must also be a multiple of 400. isLeapYear() thus decides when a year is a leap year. (see the discussion on "Hints for Assign5" to discover specific examples of a LeapYear).
The purpose of the Date.java is to decide whether a year is a leap year. Here is a definition of when a year is considered a leap year :
-year y1 is a leap year if it is multiple of 4.
-year y1 is a leap year if it is a multiple of 100, it must be a multiple of 400.
-Otherwise y1 is not a leap year.
2. The DateJDialog.java class: implements the GUI. Please use the Dialog boxes developed in the book in chapter2 in pages 99-100 in the code-listing 2-32 (NamesDialog.java) for input and output.
Remember that you will prompt the user to enter:
-a month;
-a day;
-a year
And out of these 3 you will be able to create a Date. Then you will use the dialog box to tell the user whether the year entered was a leapyear or not a leapyear.
Remember that we defined in 1- what it means a year is a leap year or not a leap year.
Do not forget to compile the 2 java files. To verify that the DateJDialog.java works, in TextPad after you compile DateJDialog.java, Click on Tools, Click on "Run Java Application".
When you have completed the assignment, please remember to submit Date.java and DateJDialog.java.
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 am working on a project where i need to show a year value in a class that extends JSpinner.Its working just fine but when i try to set an alignment value for the editor textfield it all falls apart and i know im missing something really critical here but i can't see or find it all i know is that i can't make a proper reference to the textfield component in the editor i use in the correct way or aproach.
public class JNumberSpinner extends JSpinner {
private String actionCommand;
private boolean isEnabled;
private int startValue;
private int columns;
private int alignment;
private SpinnerNumberModel model;
private JSpinner.NumberEditor numEditor;
private JFormattedTextField jTxtEditorView;
[code]....
So basically we have this question to do : Write a method dayNumber that determines the number of days in a year up to and including the current day. The method should have three int parameters: year, month, and day. If the value of any parameter is invalid, the method should print a warning message and return the value zero. The table gives some examples of the action of the method. Accept any non-negative year as being valid. You may want to assume the existence of a method numberOfDays that returns the number of days in a given month of a given year. And you should have a method call isLeapYear, if the user enter a year that is a leap year.
This is what I did so far:
class dayMonthYear {
public static void main(String[] args) {
System.out.println("Enter a year");
int year = In.getInt();
System.out.println("Enter the month for '1' to be January - '12' to be december");
[Code] ....
It works and compiles but my problem is that: let say I enter "12" for December and December has 31 days, so what my program will do since December has 31 days, it thinks each month has 31 days and add them up which will give me 372 when it's suppose to give me 365. How do I make it that it won't do that and that it will work if the year is a leap year too.
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?
We use a Java program to read an XML file and put its content into a database. We also use Date() to get the current date and insert it into a field in database with content from XML file. Everything worked flawlessly until today, the last day of 2013. We are getting 2014 for the year instead of 2013!!! System date shows correct year, so this must not be an issue.
