Wages Calculator - Determine Total Cost Of Crew Departing From Port On That Day
Nov 27, 2014
A wages calculator application is required that can determine the total cost of crew departing from the port on that day. To do this, the application reads from an itinerary text file containing each ship being loaded in the port that day, in the following format:
<ship id>
<journey id>
<l> // where <l> is the length in hours of the journey
<s> // where <s> is the number of crew for the ship for this journey
<rate> // for each s, <rate> is hourly rate of pay
Your application must calculate the total cost of the crew for each ship/journey and then compare it with a "recommended maximum journey cost" (RM) amount typed in by the user when the application is first run. If the total amount is less than or equal to RM then the details must be written to the screen and to an output text file called wagedaily.txt. If the amount is larger than RM then the results must be written to the screen only. Messages to the screen must indicate whether the crew cost is less than, equal to or larger than RM.
Your application should find the ship with the highest crew cost that is below RM and print this out as the final piece of output to the screen.
It has given me a bunch of ships and numbers to play around with in the code, here they are:
Monarch
M141
16
6
10.5
10.5

I am new to java and this is one of my first program assignments. I can't figure out how to make the if else statements work. I am trying to get the input from the user to be multiplied by the package cost but it gives me an error. I also can't figure out how to solve for the discounted total.
Purpose of the program: To write a program that asks the user to enter the number of packages purchased. The program should then display the amount without any discount, the amount of the calculated discount (if any), and the total amount of the purchase after the discount is applied.
What the output should be:
Enter the number of packages purchased: 10
Your total without discount: $990.00
The discount is: $198.00
The discounted total: $792.00
import java.util.Scanner;
public class Practice {
public static void main(String[] args) {
double packageCost = 99.00;
double amtPackage = 10.00;
double withoutDiscount = packageCost * (double) amtPackage;
[Code] .....

I'm trying to create a GUI application that calculates and displays the total cost for certain automotive maintenance services. The application should contain hree classes: 1) the main class that creates and displays the window; 2) a panel for the routine services and 3) a panel for the non-routine services. 2 and 3 are instantiated in 1. I'm pretty positive the error lies in the NonRoutinePanel class because when I comment it out of the main class the program runs fine. But I can't quite figure out which lines of code or methods are causing the problem.
When I try running the program I get these error messages:
Exception in thread "main" java.lang.NullPointerException
at java.awt.Container.addImpl(Container.java:1040)
at java.awt.Container.add(Container.java:958)
at javax.swing.JFrame.addImpl(JFrame.java:540)
at java.awt.Container.add(Container.java:926)
at JoesAutomotiveGUI.<init>(JoesAutomotiveGUI.java:38)
at JoesAutomotiveGUI.main(JoesAutomotiveGUI.java:111)
Here's my code for the three classes:
import javax.swing.*; // Needed for Swing class
import java.awt.*; // Needed for BorderLayout class
public class RoutineMaintenancePanel extends JPanel
{
public final double oilChange = 26.00;// cost of oil change
public final double lubeJob = 18.00;// cost of lube job

You have been given the job of writing a program to assist pilots who fly the Beechcraft Starship-‐‑1 executive aircraft.As with any airplane, it is essential that the pilot know the total weight of the loaded plane at takeoff and its center of gravity. If the plane weighs too much, it won'ʹt be able to lift off. If the center of gravity is outside the limits established for the plane, it might be impossible to control. Your task is to write a program that will determine the total weight and center of gravity of this plane
Inputs: The number of crew members, number of passengers, weight of the forward baggage compartment contents, aft baggage compartment contents weight, and the amount of fuel in gallons are to be accepted as INTEGER values in the order stated. Be sure the input values are within acceptable ranges
Outputs:You must echo the input values, annotated with their appropriate names,calculate and display the total weight, and the center of gravity.

I am trying to display two types of table one with initial cost and another one with new cost. Based on the java code here i already have one table but don't know how to display another table.
Attached is the sample output that i am aiming for. The output table for the above code is:
Enter the number of vertices
6
Enter the adjacency matrix
0 4 0 0 -1 0
0 0 -1 0 -2 0
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 -5 0 3
0 0 0 0 0 0
Enter the source vertex
1
distance of source 1 to 1 is 0
distance of source 1 to 2 is 4
distance of source 1 to 3 is 3
distance of source 1 to 4 is -6
distance of source 1 to 5 is -1
distance of source 1 to 6 is 2

//and a total field? beware stale data.
//store sales argument from sales field

I know that i have to fix some of the semantics . I have this code that I made earlier, is there an easy way to make it into a GUI interface? Or will I have to go throughthe code lines to add the JOptionPane? And I am a little confused on how to make a list (array) for the commission rate.

I cannot get the right output for my program. I need to get the total number of pennies in dollar amount for the output of Total Pay. This is my program. The directions are:
Write a program that calculates the amount a person would earn over a period of time if his or her salary is one penny the first day, two pennies the second day, and continues to double each day. The program should then show the total pay at the end of the period. The output should be displayed in a dollar amount, not the number of pennies. Do not accept a number less than 1 for the number of days worked.
import java.util.Scanner;
import java.text.DecimalFormat;
public class PenniesForPay {
public static void main(String[] args) {
int numDays;
[Code] ....
totalSalary should be total number of pennies / 100....However its not picking up only day 30 of pennies which is 536,870,912 pennies and then dividing it?

I'm struggling with inheritance in my assignment. The assignment states that I should use the calculatePrice() to calculate the total price and use another method to display the total. The I must overload the calculatePrice() and add a fee in the SpeedOrder() class.
My main class
package useorder;
import javax.swing.*;
public class UseOrder {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Order.display();
[Code] .....
The problem is mainly displaying the TotalPrice field and. I can't display TotalPrice if it's not static but if it's static I can't inherit it to the SpeedOrder class to assign the total in the overloaded calculateprice method. How can I display the total in my order class and use it in my SpeedOrder class?

I have created a java gui application and I need to communicate through the serial port. I would like to open the serial port in the beginning of the application and then close it when the applications closes. The problem that I am having is that I created a method to open the serial port in the main function but I can not close the serial port on exit off the application. Is there away of having the serial port be setup so that all methods can access the serial port.

I am trying to connect to Sql Server database using Oracle UCP with sqljdbc4-3.0 JDBC driver for Sql Server,with different ports and instances.
– the issue is with the port being ignored in the server string.
For example, using port 1440 connects to the default instance (which is on port 1433) rather than MSSQLINSTANCE1 which is on 1440.
Below are Server hosts used.
sql005.sqlasoftware.com (connects correctly to the default instance)
sql005.sqlasoftware.com:1440 (connects incorrectly to the default instance on port 1433)
sql005.sqlasoftware.comMSSQLINSTANCE1 (connects correctly to the named instance)

So far this is the code I have. It will successfully read the contents of the file(which are below in quotations) and write them to the designated file. My issue is totaling the corresponding costs to their services and then writing that to the file. The if and else if clauses above do not work but how is it that I can get them working?

This is supposed to get a certain number of items, and then calculate how much every item costs. It adds up the sum of those prices and checks if it is over 150$, if it is, it returns true, if it's not, it returns false.

public static boolean DelPay (int a) {
