Program That Calculates How Much Employees Earn Over A Period Of Time In Months
Oct 5, 2014
i 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
*/
package nick.employee;
import java.util.Scanner;
public class nickemployee {

Problem 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"

When 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?

Write a program that stores the total rainfall for each of the 12 months into an array of doubles. The program should have methods that return the following:
The total rainfall for the year
The average monthly rainfall
The month with the most rain
The month with the least rain
And the code:
double rain[] = new double [12];
double sum;
double average;
double most;
double least;

I succeed but with limit. the code is below. I cant use advanced material (really just the basics even without loops)
if statements are allowed, and i must use Final variables for key value.
I must use one class and one method (the main}|). I need to prompt the user for a entrance time and exit time, it must be with a space , like 18 00 and not 18:00
Also, if the entrance time is greater or equal to 18 00 the charge is always 20 dollars. If the user enters wrong data or out of range data an output of "ERROR WRONG DATA" and then the programs terminates. Same for wrong time . like if the enter hour is bigger than the exit hour an output of "ERROR entrance time must preccede exit"
for the first hour the output is "no charge",
for the second hour the charge is 10 dollars.
from the 3 hour for every 15 minutes an additional fee of 3 dollars.
for example if the user entered 10 00 and 13 20 , it should be 52 dollars
** it works for me but if the difference between the entered and exit hours is more then 3 it doesnt work. I could've added another if statements for the bigger hours but it will be very long.
I managed everything. except the last part. That calculates additional 3 dollar for each 15 minutes. what is did is.
converted everything to minutes.
subtract enter time from exit time.
and divide by 15.
thats give me the number of 15 minute periods.
if it last or equal to 4. no charge
else last or equal to 8 . 10 dollars
else...... here is the hard part.
if the total minutes wont divide even by 15 it wont work.

Its just two problems:
1.Write a Java Program that calculates the change for a cashier. The program requests the cost of the item. The user then types in the cost. The program then outputs the cost of the item including the sales tax (use 6% as the sales tax value). The program next requests and recieves the amount tendered by the customer. Finally, the program outputs a summary of all figures, including the amount of change due to the customer. Name the program as Change.java.
This program has the following attributes and methods:
double cost;
double tax;
double payment;
double getCost();
double getTax();
[code].....
2. Create a java program named Numbers whose main() method holds two integer variables. Assign values to the variables. Pass both variables to methods named sum() and difference(). Create the methods sum() and difference(); these compute the sum and difference between the values of two arguments, respectively. Each method should perform the appropriate computation and display the results. Name the program as Numbers.java.

I need getting started designing and creating a program that calculates simple and compound interest. Simple interest in this case means that interest is only applied to the original amount. For instance, if a person deposits $1000 at 10% annual interest, then after one year they would have $1100 (the original $1000 plus the $100 interest) and after two years they would have $1200 (the original $1000, plus the $100 earned the first year, plus the $100 earned the second year).
With compound interest, the interest is applied to all money earned. So, starting with $1000 at 10% annual interest, after one year the user would have $1100 (the original amount plus $100 interest) and after two years the user would have $1210 (the $1100 they started with at the beginning of the year plus the $110 interest).
The requirements of this program are:
-Create a class that will hold methods to calculate the interest. Do not include the main method in this class.
-In the class that is used to calculate the interest, include a method to print to the screen, by interest period, the starting amount for the period, the interest earned for the period, and the total amount at the end of the period. Note that each period represents the time frame for how often it is updated. If annual is selected the period is every year. If it is semi-annual it is every six months. If it is quarterly it is every three months.
-Create a demo class that will use your interest calculation class. Prompt the user for the original amount, the type of interest (simple or compound), the annual interest rate, and whether it is updated annually, semi-annually, or quarterly. Use method calls to your calculate interest class to do all calculations and display the result. Loop the program until the user chooses to quit.
Sample output ($10000 initial investment, 10% simple interest, annual, for 4 years):
Period Beginning Amount Interest Earned Ending Amount
1 10000.00 1000.00 11000.00
2 11000.00 1000.00 12000.00
3 12000.00 1000.00 13000.00
4 13000.00 1000.00 14000.00

Write a Java program that calculates the area and volume of a cube, sphere, cylinder, and regular tetrahedron. Your program should obtain the necessary input for each of the objects from the console and output the input, area, and volume of the object. Use appropriate messages to guide the user of your program.

If my xml file (shown below as sample) has different employees with id's - is there a way I can get just the id's on there own?
Java Code:
<Employees>
<Employee id="1">
<age>29</age>
<name>Pankaj</name>
<gender>Male</gender>
<role>Java Developer</role>
</Employee>
<Employee id="2">
<age>35</age>
<name>Lisa</name>
<gender>Female</gender>
<role>CEO</role>
</Employee>
</Employees> mh_sh_highlight_all('java');
This is the code Im using - I know at the minute it gets the id details of id 3 but realistically I just want the id's and nothing else
Java Code:
private static String getEmployeeById(Document doc, XPath xpath, int id) {
String env = null;
try {
XPathExpression pathExpression =
xpath.compile("/Employees/Employee[@id=3]"); // line gets everything to do with id 3 but doesn't display the id
[code]....
Can this be achieved using xpath? I've been stuck on it for ages and I can't seem to really find anything to do with it

I have now four types of employees. Managers (who receive a fixed weekly salary), Design workers (who receive a fixed hourly wage for up to the first 40 hours they work and "time-and-a-half," i.e., 1.5 times their hourly wage, for overtime hours worked), Sales workers (who receive a $250 plus 5.7% of their gross weekly sales), and Manufacturing (who receive a fixed amount of money per item for each of the items they produce -- each manufacture in this company works on only one type of item). and here are my classes:
employee class
the problem is i get this output:
You chose to open this file: Employees.txt
John Smith Manufacturing 6.75 120 444
0.0
Betty White Manager 1200.0 0 111
0.0
Stan Slimy Sales 10000.0 0 332
250.0
Betty Boop Design 12.5 50 244
0.0
meaning that it is getting 0 for all my calculations and leading to this weekly report:
WEEKLY PAY REPORT FOR Wacky Widgets COMPANY
Employee
0
WEEKLY PAY
250
Total Payroll: $0.0
Total number of managers paid:1
Total number of Design Employees paid:1
Total number of Sales Employees paid:1
Total number of Manufacturing Employees paid:1
fixing my methods so they can accept the integers of the file and use them in the calculation since all im getting at the moment are 0 values.
here is the abstract class from which all the other employees type are extending from
public abstract class Employee {
public abstract double calculateWeeklyPay();
private String fName;
private String lName;
private int EmpId;
private Position p ;

I was wondering how can I calculate total age in months and store it as variable? this is what I have so far:
*
* You will ask the user to provide their name (as a single word, assume first name here)
* You will ask the user their age in full years (no fraction or months)
* You will ask the user how many full months since their last birthday (again, whole numbers here).
*
* You will use this information to calculate the user's age in months and use that information to print out a greeting.

I have to create a method to find the current month with the input being a number of milliseconds using System.currentTimeMillis(). Now I was able to solve the problem with the following extremely cumbersome method:
public static int monthLeap(long ms) {
int result = 0;
int jan = 31, mar = 31, may = 31, jul = 31, aug = 31, oct = 31, dec = 31;
int apr = 30, jun = 30, sep = 30, nov = 30;
int feb = 28;
int febLeap = 29;
[Code] ....
I first go through a loop that goes through all the years and subtracting the number of days of a normal year or a leap year in milliseconds from the total milliseconds. At the end I should have a rest value of milliseconds that represents the amount of milliseconds that have passed already this year. Out of this number I then find the month we are currently in.
My problem is that the above method is way to large and I get a checkstyle warning: "NPath Complexity is 12,288 (max allowed is 80)".
I know that this can somehow be solved with a for loop iterating through the time and counting up months until there is no more month left. My problem though is the different lengths of the months. If each month was the same I could just subtract the amount of days in each month from the rest value.
(Since I already got it down to <= 12 months, I shouldnt bother with the extra days to find the month. Yet if I want to find the month when the date is the first or last day of the month it is important to be very precise) ....

So, here is the question I have been working on: Write a java class named Time that prompts the user to input the elapsed time for an event in seconds. The program then outputs the elapsed time in hours, minutes, and seconds. (For example the elapsed time is 9630 seconds, and then the output is 2:40:30 ).Hint: an hour has 3600 seconds and a minute has 60 seconds. Use Scanner class for reading the input.
Here is my code:
import java.util.Scanner;
public class Time {
public static void main(String[] args) {
Scanner scan= new Scanner(System.in);
System.out.println("Enter the elapsed time in seconds:");
int totalseconds= scan.nextInt();
[Code] .....
Now, I know I am supposed to use the remainder operator to figure out the time in minutes and seconds, but the hours has be a little confused. Right now this code compiles but gives me an exception.

24-hour Clock 12-hour Clock
-----------------------------
00:00 0:00 a.m.
00:15 0:15 a.m.
00:30 0:30 a.m.
00:45 0:45 a.m.
01:00 1:00 a.m.

What I'm supposed to be doing is making it so the program can accept multiple filter and sort commands at one time, and each should be separated by a whitespace.I was thinking about parsing the input again, using whitespace as the delimiter, then normally progressing with each token, as though there was only one command.
However, coding this the way I'm doing it will firstly probably take hours, and secondly, it's likely not even right. I don't have any real way to determine which token contains which data from the Song objects.These are the specific requirements for this portion:A sort/filter command consists of one or more of the following options:
-year:<year(s)>
-rank:<rank(s)>
-artist:<artist>
-title:<title>
-sortBy:<field>
Any number of these options may be given, and they may be given in any order. If multiple options are specified, they will be separated by whitespace.

One 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?
