Java Time Zone Transition Period From EDT To EST?
Oct 28, 2014Problem statement: Convert "2014-11-02 01:00:15 EST" to GMT.
This seems easy enough. But why is the below code giving the wrong answer?
Background:
* EDT aka GMT-4
* EST aka GMT-5
* 2014-11-02 01:00:15 EST == 2014-11-02 06:00:15 GMT
* If I user the commented out date string it works!!!
* EDT(until Nov 2, 2014 at 2am) -> at 2am we go to 1am EST
* If I use the below commented out from string it work!!! But these are equal (2014-11-02 01:00:15 GMT-05:00 and "2014-11-02 01:00:15 EST)
Code Example:
ZoneId gmt = ZoneId.of("GMT");
//String from = "2014-11-02 01:00:15 GMT-05:00";
String from = "2014-11-02 01:00:15 EST";
final DateTimeFormatter dateTimeFormatterone = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss z");
ZnedDateTime zonedDateTime = ZonedDateTime.parse(from, dateTimeFormatterone);
ZonedDateTime gmtzonedDateTime = zonedDateTime.withZoneSameInstant(gmt);
String result = gmtzonedDateTime.format(dateTimeFormatterone);
This is what the outcome is.
result == "2014-11-02 05:00:15 GMT"
Shouldn't it be
result == "2014-11-02 06:00:15 GMT"
Determine Distance The Object Falls In Specified Time Period
Apr 3, 2014When an object is falling because of gravity, the following formula can be used to determine the distance the object falls in a specified time period:
d = 1/2 gt^2
The variables in the formula are as follows: d is the distance in meters, g is 9.8, and t is the amount of time, in seconds, that the object has been falling.
Write a method named FallingDistance that accepts an object's falling time (in seconds) as an argument. The method should return the distance, in meters, that the object has fallen during the time interval. Demonstrate the method by calling it in a loop that passes the values 1 through 10 as arguments, and displays the return value.
import java.util.Scanner;
import java.text.DecimalFormat;
public class FallingDistance
{
public static void main(String[] args) {
DecimalFormat num = new DecimalFormat("#,###.00");
Scanner keyboard = new Scanner(System.in);
double fallingTime;
[Code] ....
My program runs, but no matter what falling time I enter, I get the same numbers. What am I doing wrong?

View Replies View RelatedProgram That Calculates How Much Employees Earn Over A Period Of Time In Months
Oct 5, 2014i am very new to java programming what i am doing wrong here. Write a program that calculates how much an employee would earn over a period of time (in months), if, every month, the employee’ pay-per-hour rate is one dollar more than the month before (so if his starting perhour rate is 7.25, next month it will be 8.25, next month 9.25, and so on). The employee is going to work 20 hours per week, 4 weeks per month.
The program should input from the user and validate both number of months (which should be a positive integer larger than 0) and the pay-per-hour rate (which should be a floating-point number larger than $7.25 – the minimum federal wage pay-per-hour rate). For each one of these values; if the value is wrong, the program should repetitively ask for that value until the value entered is correct. The program should confirm/output the correct value.
/*
This program calculates how much as employee would earn if every month the employee pay per hour would increase by a dollar

JSP :: Dynamic Menu Duplicates Every Time A Link Is Clicked

Sending To All Vs Sending To One Person In Server / Client Program
Apr 17, 2014I have two programs that I'll post below, one is a Server and the other is a Client. The ChatServer runs once and many clients can run ChatClient from separate computers and talk together in their GUI's. The the client program comes with two buttons, one that's simulates the sending of a message to a single user ; "Send Message To User", and one that just generally sends a message ; "Send Message To All". Although now the Clients on the server seem to be able to selectively send messages to an individual by giving the recipient name, all the clients can see that message, which is not exact what I am aiming for. What I am going for is having the "Send Message To User" button click to send a message to the named user without all other users seeing the message.
The Server Program Code
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
[Code] ....
Now I have tried thing like having various input output streams and trying to connect those, but no luck. Tried fiddling with having the names arraylist directing the messages to one client versus all but that did not work out either. How I what I would need to do to go about doing this?

View Replies View RelatedExtract Higher-order Bits Of Random Number In Order To Get Longer Period
Mar 1, 2014One of the random number generators in Java extract the higher-order bits of the random number in order to get a longer period.
I'm not sure if I understand how this is done. Suppose that the random number r = 0000 1100 1000 1101. If we extract the 16 most significant bits from r; is the new number r = 0000 1100 or r = 0000 1100 0000 0000?

View Replies View RelatedMilitary Time - Adding Minutes Displaying Correct Time
Feb 9, 2015I am working on an assignment that I can't seem to figure out the final part to. The program takes in course data such as the time the class starts and how long it lasts. The time is in military time (0000 - 2400)
I need the output time to be the time the class started, plus the length of the class, and displayed in military time.
for example,
Start Time = 0930
Length = 50 minutes
Endtime = 1020
I can't for the life of me figure out how to do this. I have gotten a program that works for this time and minutes, and displays the correct 1020. But when I change the information to say
Start time: 0700
Length = 90 minutes
I get:
Endtime = 90
90 is technically correct, the way the formula is setup, but I need it to display 0900 not 90.
Here is the code that I have. Be easy, I'm still learning, and this is just the file I created to get the formula to work. Also, the verbose in here is just for my own debugging to make sure values should be what I'm expecting them to be.
public class calc
{
public static void main(String[] args) {
double hours, minutes, length;
double temp;
int time = 2400;
hours = time / 100;
System.out.println("Hours are: " + hours);

How To Create And Link Two Classes
Apr 16, 2014i have tried moving the
//create line
Point beginOfLine = new Point(point1, point2);
//ask user for second pair of coordinates
System.out.print("Enter the coordinates for X2 or <Random> or <Exit>:");
userInput=keyboard.nextLine();
code part to another class but nothing..this is what a second class should be doing
1 - Write a java class called Point to represent a 2-D point (With x and y)
- The constructor should take the x & y as double
- The class should have accessor / mutator methods for all coordinates
2 - Write a java class called Line to represent a line (with a starting point and an ending point)
- The constructor arguments are the start and end points
//import utilities to be used in the program
import java.util.Scanner;
import java.util.Random;
public class Point {
//declare variables
private double pointX, difX;
private double pointY, difY;

View Replies View RelatedConverting Military Time To Standard Time?
Jan 29, 2014I have two classes. time_runner is used for testing my code.
This is what I'm using to test my code:
class time_runner
{
public static void main(String str[]) throws IOException {
Time time1 = new Time(14, 56);
System.out.println("time1: " + time1);
System.out.println("convert time1 to standard time: " + time1.convert());
System.out.println("time1: " + time1);
System.out.print("increment time1 five times: ");
time1.increment();
[code]....
The two constructors are "Time()", which is the default constructor that sets the time to 1200, and "Time(int h, int m)" Which says If h is between 1 and 23 inclusive, set the hour to h. Otherwise, set the hour to 0. If m is between 0 and 59 inclusive, set the minutes to m. Otherwise, set the minutes to 0. Those are my two constructors that I pretty much have down. The three methods however I'm having trouble with. The "String toString()" Returns the time as a String of length 4. The "String convert()" Returns the time as a String converted from military time to standard time. The "void increment()" Advances the time by one minute.
public class Time {
private int hour;
private int minute;
public Time(int h, int m) {
if(h > 1 && h < 23)
hour = h;
