Java Date Function Minus Operation Excluding Weekends And Holidays
Feb 12, 2014
I have deduct a number of days excluding holiday and weekends .So if I have to deduct 4 days from current day (02/12) and assuming 02/10 is a holiday my answer will be 02/05
Now below is the code I have come up with however its not working with the hardcoded dates I am passing in to the Holiday Calendar String .Only the last value is considered . How I should store this values and compare with the date
package date_calculation;
/**
* Returns a tick for each of
* the dates as represented by the <code>dtConstants</code> or the list of <code>dtDateTimes</code>
* occurring in the period as represented by begin -> end.

I am trying to build an app for managing expenses to practice with java programming. I am stuck on the ActionEvent block. The program i am trying to make needs to minus the expenses from the monthly income and display the net income in JLabel.
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...
I like to know how to write root function in java applet. I know it in java function. Ex:
import java.lang.*; public class Maths { public static void main(String[] args) { // get two double numbers numbers double x = 9; double y = 25; // print the square root of these doubles System.out.println("Math.sqrt(" + x + ")=" + Math.sqrt(x)); System.out.println("Math.sqrt(" + y + ")=" + Math.sqrt(y)); } }
working fine. but If I tried in applet it's not working. Ex:
I need to convert c# function to java method. The important thing is String strKey. Parameters for testing are strMask= 4634958 and strSN=1394901184 and the result must be strKey = 2156325482!!! The result that I am getting with my Java code is 2138641814.This is C# code:

I want them to sort them as per below result: (Same date one should be sort by timestamp)

I tried using Collection.sort using compareTo but result is not expected...

I have a piece of code as below for date format conversion.
DateFormat formatter1 ; DateFormat formatter2 ; Date date = new Date();
formatter1 = new SimpleDateFormat("yyyy-mm-dd"); date = formatter1.parse("1952-12-10"); System.out.println("before format, date is " + date);
formatter2 = new SimpleDateFormat("dd-MMM-yy"); formatter2.format(date); System.out.println("after format, date is " +formatter2.format(date));I would like to change 1952-12-10 become 10-DEC-52, h
However, I am getting below output:
before format, date is Thu Jan 10 00:12:00 MYT 1952 after format, date is 10-Jan-52
There is an error in my code that pops when I tried to execute my java application for an exponent function that I wrote. Here is my code and here is the error is generated when I run my code:
//a java application that calculates the power of an integer in a method that the user creates //and uses a while loop to do so. User cannot use any Math class methods to perform this calculation
import java.util.Scanner; public class exponentiation{ //main method begins execution of java application public static void main(String[] args){
[code]....
Why is it an illegal start of an expression? I didn't think you needed to used if statements for a whileloop.
I am making a pizza program and most of the program works. I have made an order button that will output the total price of the order. The reset button that I made makes the JTextArea output $0.00, but if I press the order button to make another order, the program does not add the new amount to zero. For example, if I make an order that totals $5.00, but I want to make another order after resetting, the price for the new order will be added on to the previous order's price.
Here is the code. This is a JApplet program. Why the price will not reset? This code was made in BlueJ.

i need a java library function that searches the stream of tcp packets coming to my computer from a particular ip address, so i can perform regular expressions on the contents of those packets.
In my project i am facing an problem, The My SQL Data base will accept the date format of yyyy/mm/dd only as "Date" data type but in my program i wants to use dd/mm/yyyy format. (i have this same format now) that's why I am unable to insert / retrieve it..
Having an issue with an application I'm testing that takes in several Date parameters from a user, while testing I've noticed if i enter a date that's in or before 2034 everything works fine but once i go from lets say 21/08/34 to 21/08/35 the year reverts to 1935, not 2035.
I'm using the java.util.Date Class to store the Data entered... is there any known restrictions on the Date class that might be causing such an issue??
So I have a program for a project that permutes a random series of numbers using Java's Rand function. Basically I use a seed and a number of items I want in the arrangement of numbers, and the program makes a permutation with no two numbers being repeated. Only arrays can be applied to it, so I've been hard at work finding a solution.
Here's the code so far:
public static int permutation[]; public static void permute(int numOfItems, int seed){ permutation=new int[numItems]; Random rand = new Random(seed); permutation[0]=rand.nextInt(numItems-1);
[Code] ......
So basically I'm wanting the program to make a randomized list of numbers from the number of items I pass to the Permute method with no duplicates. I'm having some level of success with what I have written, as it gives me a randomized list when printing the output, but for some reason the first for statement in code never terminates fully, but instead runs indefinitely when generating the last integer.
For example, if I want to put 10 with a seed of 0 into it and make a list from 0-9, it will print 74283510, which is only 8 different integers. permutation[0] is manually set at the beginning of the method, which accounts for one more, but that's still only a list of 9, so I'm just wondering why the last integer is not being generated and why the program keeps looping and not terminating? I'm know for sure it's something I'm overlooking.
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.
