Date Comparisons Not Working
Sep 24, 2014
I am having a hard time getting some comparisons with Date to function correctly.I have a driver program and two classes, ZodiacDriver , ZodiacSign and ZodiacTable. In the driver program I build an arraylist of zodiacsigns in zodiactable. That all appears to be working I then pass a birthdate and the zodiac table to a method, determineSign. This is where I am having trouble. Right now Im just trying to match the incoming birthdate with a zodiac's date in the table. however no matter what date I enter, i get pisces, which happens to be at the bottom of the list. If I remove pisces from the list I get the current last zodiac. Here is my code:
ZodiacDriver
Java Code: package zodiac;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.*;
[code]....

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 want to generate a Hash key for a [ Nested Hierarchical nodes]. Any lightweight non-cryptographic hash map functions which generate a key, so that I can use this hashkey to comparison purposes.
NOTE: Security is not a concern for me, I just want to create a Unique ID.

I have a HashSet, which I created to prevent duplicates upon output, but of course it's printing duplicates(or else I wouldn't be posting this). The order of my output does not matter, nor the input. The data type is String in the format (x + "," + z), where x and z are integers, creating a collection of coordinate sets. So to prevent the output of duplicates, I'm trying to get rid of the duplicates before they are added to the collection.
I've tried doing a '.equals()' string comparison but what happens is, since my string is added via one variable, it compares itself to itself and if itself equals itself it won't be added to the collection. I really need to keep this as a comparison of a single variable, because creating a key for each value would be sooo ridiculous for this volume of inputs.
So, with that being said, I would like to add one copy of the string, discard the duplicates, and do this thousands of times..

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.

write the algorithms of the following problems.
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 ...)

I have three sorting algorithms in which I must count the number of swaps/copies and comparisons. I am meant to only count the swaps and comparisons that involve anything other than indexes as they are too fast to really matter (according to the professor). My counters are in the right position or not. I keep coming up with swaps/comparisons that don't necessarily match the formulas I'm finding for best/worst case. Makes me think that my counters are somehow out of place or that I don't have enough of them.
Insertion Sort:
public class InsertionSort {
public static void insertionSorter(int[] array) {
int firstValue; // first value in array
int scan; // scan array through the array
int moves = 0; // number of moves
[Code] ....

My objective is to execute quick sort ( i was told to convert the pseudocode from the Cormen book) using arrays of increasing sizes and find the average number of comparisons for each of those sizes over 100 iterations. This is a school project and the numbers I am getting are far larger than those of my friends, so I am clearly doing something wrong. I believe it must be in the way that I am collecting and averaging my number of comparisons. I will first give the method in which most of that calculating is done, then I will include the whole program.
public static void tests(int arraySize) {
long numComparisons = 0;
long averageComparisons = 0;
long[] numComparisonsArray = new long[100];
for(int i = 0; i<100; i++) {
int[] array= genRandomArray(arraySize);
[code]....
I was simply not zeroing out one of my variables

I have to count the comparisons in the quick sort. I have done it by using a global variable. But I am stuck in doing it recursively.
This is my code.
import static java.time.Clock.system;
import java.util.Arrays;
public class test {
/**
* The swap method swaps the contents of two elements in an int array.
*
* @param The array containing the two elements.
* @param a The subscript of the first element.
* @param b The subscript of the second element.
*
*/

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 am looking for 01,02,03 etc...

why the default date format that the textbox accepts is in 'mm/dd/yyyy'.For example if i entered "13-05-2014" then it would return an error stating date is invalid.If i entered "12-05-2014" then it would return "5 Dec, 2014".I did not declare any dateformat anywhere except for the datepickers which as shown above, is 'd MMM, yyyy'.Before this happened i trialed and error many different kind of codes to try to validate the date however it all didnt work and so i reverted it all back to the original codes.Last time the dateformat that the textbox accepted was 'dd/mm/yyyy' and it worked fine with my javascript function except the validation part.
Now it still works except that the dateformat changed to 'mm/dd/yyyy'.I did try to use console.log to find out what's wrong but there were no error messages.Why has the dateformat changed by itself?

When trying to convert the time zone of a date I encountered the log below. java.lang.IllegalArgumentException: Cannot format given Object as a Date..Here is what my code looks like:
1. First I will get the date from the email header by the following code.
String messageDate = (String) mail.headers["Date"];
Output: Wed, 4 Jun 2014 18:30:05 +0800
2. Next I will convert the timezone to EST.
SimpleDateFormat timeZoneConvert = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss Z");
timeZoneConvert.setTimeZone(TimeZone.getTimeZone(" EST"));
String l_MailDateEST = timeZoneConvert.format(messageDate.trim());
Once the code run I encounter the said error.

I have date in string ex: 2014-08-08T17:38:58.316+05:30 and want to convert into 2014/08/08 17:38:58. I am using below code :
String date1="2014-08-08T17:38:58.316+05:30";
SimpleDateFormat formatter, FORMATTER;
formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
String oldDate = "2011-03-10T11:54:30.207Z";
Date date = formatter.parse(oldDate.substring(0, 24));
FORMATTER = new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss.SSS");
System.out.println("OldDate-->"+oldDate);
System.out.println("NewDate-->"+FORMATTER.format(date));
this giving me required value, but when i replace oldDate with date1 it shows me exception that not parse to date. Actually i am getting date in string of 2014-08-08T17:38:58.316+05:30 which i need to convert into date 2014/08/08 17:38:58. To convert into date i am using below code :
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/M/yyyy hh:mm:ss");
Date datecomp1 = simpleDateFormat.parse(String );
The issue is to convert 2014-08-08T17:38:58.316+05:30 into 2014/08/08 17:38:58.

Java Code: LocalDateTime dt = LocalDateTime.now();
ZonedDateTime zdt = dt.atZone(ZoneOffset.UTC);
System.out.println("time: " + zdt);
// output:
time: 2014-06-02T13:37:55.705Z mh_sh_highlight_all('java');
13:37 is local time. Utc time is 17:37.
