I have searched for totalPay is always 0 and the responses are not related to my problem (that I can tell).This is a class assignment and I have other questions besides why the method is not working.
Here are the instructions: Create class Employee which contains a String variable Employee Number, a String variable Employee Name, an integer Hours Worked, and a double Pay Rate. Create get and set methods for each variable. Provide method "totalPay" which calculates and returns the total pay by multiplying the hours worked by pay rate. Use figure 8.12 as an example of an object with get and set methods.
Unlike other examples of this type question online this one has Employee Number as a String variable. The book is How to Program Early Objects by Deitel 9th edition.We have instructions to do only what she has told us too. At this point it is objects and getter and setter methods. It is only the beginning of week 2.
ON THE LINES WHERE I HAVE QUESTIONS I AM COMMENTING IN ALL CAPS. NOT SHOUTING, JUST TRYING TO MAKE IT EASIER
package test11; import java.util.Scanner; public class Test11 { public static void main(String[] args) { Scanner input = new Scanner(System.in);
[code]..
Essentially I cannot figure out how to get the method getTotalPay to be called by the Scanner and do the math. I also have this random bracket problem that showed up about an hour ago.
The concept I don't get is that if I omit this.employeeNumber =id; etc. I error all over the place. If I change it to this.employeeeNumber = employee Number Netbeans tells me it is assigning itself to itself, which I know. When I try to use id instead of employeeNumber I get errors all over. If i remove "this" from it the same happens. why in public class employee I have to change to those values (id, name, etc) in the construct and set them again? I don't see where or how they can be used, so why do i have to do it?
I want to make a simple game and learn java by experimenting with it.I don't know how to increase a value by clicking it.I know how to make my objects move in my small game with mouse or keys, but I also got a score var that I want to increase per click. I can increase it over time, but after 2 hours of trying I couldn't progress any further.This is the piece of code I used, I imported the class, got getters n setters and all of that...
if(e.getButton() == MouseEvent.BUTTON3) hud.setScore(hud.getScore() + 555); Whenever I click I get an error, if I remember right "NullPointerException" is when something is missing I'm probably not targeting the value correctly... Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at com.tutorial.main.MouseListens.mouseClicked(MouseListens.java:22) at java.awt.Component.processMouseEvent(Unknown Source)
why my code isn't working. I have to make it so that any time over 40 hours results in time and a half (1.5). Whenever I run the code, it makes it as if EVERY hour is time and a half when it shouldn't be.
import java.util.*; public class lab3 { public static void main(String []args) { double grosspay, pay, hours, federal, fica, state, totaltaxes, netpay; Scanner input=new Scanner(System.in); System.out.println(""); System.out.print("Enter Your Hours Worked: "); hours=input.nextDouble(); System.out.print("Enter Your Pay Rate: "); pay=input.nextDouble();
I was wondering what the easiest way would be to keep track of everytime someone makes a new post on reddit (social media site, for those who don't know). I want the program to keep track of the number of posts made with a counter, but that's the easy part. How do I set up a program to actually communicate with and monitor reddit's servers in this manner?
When I try to write the .xlsx file using apache POI, XSSFWorkbook API and run this program in Eclipse STS, I am getting the java.lang.OutOfMemoryError: Java heap space error. Then I searched the net and add these -Xms512m -Xmx1024m in the eclipse VM arguments. Even though I am getting the same error. Again i increase heap size but i am getting the different error like "occurred during initialization of VM, Could not reserve enough space for object heap". how to increase the heap size or any other API to read, delete and write the .xlsx file. I am having 4GB ram in my machine. Apache POI is very good for .xls but if it is .xlsx performance wise it is very slow.
I'm working on a program to create a blackjack game using objects (one for card, deck. and hand). Withing my hand object I am trying to add cards to the hand but it is only adding the last card i try to add and giving null values for the the ones before.
class BlackJackHand { private BlackJackCard [] hand; public void addToHand(BlackJackCard c) { if (hand == null) { BlackJackCard [] tempHand = new BlackJackCard[1]; tempHand[0] = c; hand = tempHand;
[Code] ....
What I want this section to do is add cards to the current hand. I was intending for it the hand to be null at first and the if(hand == null) piece to add the card the first time and then the else piece would be used when the hand already has at leas one card. I want the else section to create a temporary array that is one larger than my current hand, copy the cards from the old hand to the new hand, and then add a new card to the last space before rewriting the old hand as what the temporary hand is.
The code I am using to test if the addToHand() is working is
class BlackJackTest { public static void main (String[]args) { BlackJackCard c1= new BlackJackCard(1,0); BlackJackCard c2= new BlackJackCard(1,4); BlackJackCard c3= new BlackJackCard(1,5); BlackJackHand h1 = new BlackJackHand();
[Code] .....
BlackJackCard has the parameters (int suit, int value)
This should print: ace of clubs 4 of clubs 5 of clubs
I have been playing around all day trying to get this to increase the value of number by one after each new runner is added. How to get the value of number to increase after each record is added?
public class Runner { /* static variables */ /* instance variables */ private int number; // runner's number private String name; // runner's name private String ageGroup; // standard, junior or senior private int time; // runner's marathon time in minutes
I was making a pong game, part copied code off the internet, part my own code, part my friends code. It works well enough, but the ball starts at one speed, and stays the same. I would like to know how to make the ball slowly increase.
It is a java applet, which shouldn't casue any harm right?
My code:
Pong Applet
import java.applet.*; import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Pong extends Applet implements MouseMotionListener, KeyListener {
I was wondering where is the memory allocated for an applet; by the browser; by the JVM; some applet specific java option? I get an out of memory error when running my applet (loading pictures).
What I have to do: Use Applet to create two instances of the Employee class. Display the data on the Graphics object. Display in the applet the names and values of all of the instance variables in each instance of the class. Also display the value of any static variables.
What I'm doing:
import java.applet.Applet; import java.awt.*; public class EmployeeApplet extends Applet { public static int topSalary = 195000; int hoursPerWeek; public static void setTopSalary (int s) { if (s > topSalary)
[Code]...
I'm not able to display hours per week for e1 and e2.
I'm just trying to append new employee information to a previously created file. When I type yes to add new employee and enter a string, the data does not appear in the file.
Java Code:
public class Records { public static void main(String [] args) throws IOException { Scanner input = new Scanner(System.in); FileWriter fw = new FileWriter("dbs3.java", true); BufferedWriter bw = new BufferedWriter(fw); PrintWriter pw = new PrintWriter(bw);
Whenever i perform any operation in my application Live Bytes of a particular Instance of a class increases by 1000.Although i perform the same operation everytime it always increases by 100 or 1000.Is this a memory leak or does these instances increase everytime we perform an operation.
I'm trying to create a circular array which prints out 8 numbers that increase by one and don't exceed 9. If they do, the remaining numbers are printed from 0 on-wards. I have code below which does this job, but it doesn't really use an array to loop back.
Java Code:
package Practice;
public class Practice { public static void main(String[] test) { number(7); number(9);
Basic console java program. I need to generate an employee id. I have an employee class that I will paste here so you can see my fields and constructors.
public class Employee { private String firstName; private String lastName; private int id; public int nextUniqueId = 0; public Scanner sc = new Scanner(System.in);
Every year, she has to plan when her employee's can go on vacation for the summer holidays - MANUALLY. It takes weeks to solve the puzzle, because she has several kinds of employee's hired, with different skills. And at all days there must be X amount of employees with skill1 at work, plus Y amount of employees with skill2 etc, and they also need special "off-days" in comparison to when they last worked and so on. It's quite the math puzzle.
I've worked a little with C#, and built a prototype of a Support System (Ticket based), so I got the basics down of programming, and I know Java and C# are quite alike, so I don't think making the switch will bother me that much.
The program should be easy to use for her, so it needs a visual calender that can be interacted with, and it should also be easy to see which employee is at work at that date and so on.
Will it be hard for me to build this kind of Calender, that allows the interaction I want?
Any open-sourced projects, or libraries that will make my task easier?
I have this assignment to build an employee time clock. By using a menu you can enter an employee, enter punch in and out, and report.When I created the punch screen I wrote the in and out records to a file. Because there can be several employees punching in or out the file wrote each occurrence on different lines. Now I am attempting to write the report which you enter an employee Id and loop through the file to find the in and out date and then calculate the time (hours worked). I loaded the file into an Arraylist but now I cannot figure out how to loop through find the In and Out date - calculate the hours worked and then move on to the next day. here is the format of the file - employee id, place holder I or O, date, time, day. and sample
I have to read in a file that that has Student, Employee, Faculty....such as name, last name, salary...etc
Example of a file input Java Code: Student, John, Doe, [email]johnDoe[At]yahoo.com[/email], 123,Wonderland Ave, 21323,TX PhoneNumber,Cell,111,222,3333 Student, Jesus,Satan,[email]jesus[At]satan.com[/email,666, HeavenHell Dr., 666666,CA PhoneNumber,Work,111,333,5555 mh_sh_highlight_all('java'); Java Code: while(input.hasNext()){

There is more code, but it's repetitive. Now, I keep getting an error. Array of bounds. I believe i get the error because the phone number. The phone number is on the next line..I created a different arraylist for phonenumber, but I dont know how to match it with the correct person, student, employee...etc.
import java.io.*; public class workhours{ public static void main (String args[]){ try{ BufferedReader breader=new BufferedReader(new InputStreamReader(System.in)); String days[]={"Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"};
I'm making a program that displays information for "employee" objects of different types. This works with a hierarchy that goes Person→ Employee→ Fulltime/Adjunct, and a driver that tests the inheritance. The Person class is given and only supplies the name, the employee class manages the year hired and the ID, and the types of employee classes manage the salaries.
One object (called staff[2]) is supposed to first be printed with default information and then later updated via set methods. I figured out how to update the name, but I don't know how to update the rest of the information because the employee's name is managed in the Person class and the reset of the information is managed in the less-general classes, and the objects are all in an array of Person.
How do I call the set methods necessary to update more of staff[2]?Output (scroll to see the updating section)
