Program That Will Determine Total Weight And Center Of Gravity
Sep 18, 2014
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.
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:
I'm working on a Weight Conversion program. The code I have for the program is:
import java.util.*; import java.awt.*; import javax.swing.*; public class Frame4a implements ActionListener { public static void main(String[] args) { JFrame f = new JFrame("Weight converter"); JPanel P = new JPanel(); // Make a JPanel;
[Code] .....
The errors I'm getting are:
Frame4a.java:33: error: class, interface, or enum expected public void actionPerformed(ActionEvent e){ ^ Frame4a.java:37: error: class, interface, or enum expected double kp= Double.parseDouble(strkilo);
I want to write simple game. Why if I press button UP and RIGHT it not move diogonally, may be it have special code. And how I need to write correctly border and gravity?
public class Main { public static void main(String args[]) { JFrame frame = new JFrame("Stickman"); Ground ground = new Ground(); frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE); frame.setSize(710, 480);
I was tasked with building a program that counts vowels in a phrase or word. I have this working properly, but the problem arises in the next situation. Here is my code:
Scanner userInput = new Scanner(System.in); int userDecision; String Choice; String Phrase; int vowelCount = 0; System.out.println(" This program will count the number of vowels in it.
[Code] ....
As you can see, I used a 'for' statement to declare how long the program should run. However, I need the user to be able to say when it ends. For example, at the end of the program it must say "There are ______ number of vowels in your word. Please press '1' to run the program again, or any other number to exit."
I understand a do-while loop is needed here, but every time I try and create an adequate loop with no logic errors, I either break my existing code, or the program does not work correctly.
Basically, my question is, what is the best way to perform this task? Is a do-while loop necessary, or is there a better way?
write a program to determine the sum of the following harmonic series for a given value of n:1+1/2+1/3+.............................+1/n the value of n should be given interactively through the keyboard.
So basically we have this question to do : Write a method dayNumber that determines the number of days in a year up to and including the current day. The method should have three int parameters: year, month, and day. If the value of any parameter is invalid, the method should print a warning message and return the value zero. The table gives some examples of the action of the method. Accept any non-negative year as being valid. You may want to assume the existence of a method numberOfDays that returns the number of days in a given month of a given year. And you should have a method call isLeapYear, if the user enter a year that is a leap year.
This is what I did so far:
class dayMonthYear { public static void main(String[] args) { System.out.println("Enter a year"); int year = In.getInt(); System.out.println("Enter the month for '1' to be January - '12' to be december");
[Code] ....
It works and compiles but my problem is that: let say I enter "12" for December and December has 31 days, so what my program will do since December has 31 days, it thinks each month has 31 days and add them up which will give me 372 when it's suppose to give me 365. How do I make it that it won't do that and that it will work if the year is a leap year too.
I am trying to write a program that basically determines the max amount of units sold and displays it in a dialog box. Also, the program will display the winning sales associate out of 10. I have wrote the program successfully so far and I can see the maximum number of units sold displayed in the dialog box, but I cannot seem to link the winning sales person.
Here is the code I have typed so far.
//Program to find maximum of three number
import javax.swing.JOptionPane; import java.util.Scanner; public class Sales { public static void main (String[] args) { //Declare variables int num1, num2, num3, num4, num5, num6, num7, num8, num9, num10; int large; int winner;
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
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?
So I've attempted a for loop for this type of problem:If you receive $0.01 on the first day of your allowance, and the daily rate doubles each day after, calculate the total earnings for 30 days.
Output should be like: Day ----- Daily allowance - Total allowance 1 -------- 0.01 -------------- 0.01 2 -------- 0.02 -------------- 0.03 3 -------- 0.04 -------------- 0.07
My code so far:
public class Allowance { public static void main (String[] args) { int day = 0; double daily = 0.0; double total = 0.1; System.out.println("Day Daily Allowance Total Allowance"); for(day = 0; day <= 30; )
"Create a project called RainFall and a class nameD RainFall. Write a program that stores the total rainfall for each of 12 months into an array of doubles. The program should display total rainfall for the year, the average monthly rainfall, the month with the most rain and the month with the least rain. When outputting the month with the most and least rain, output the name of the month. This is what I have so far.
Recently I have missed a few weeks of my class due to family emergencies. Because of this I have missed very important lectures. My professor has assigned me the following assignment:
Prices Write a Java program that specifies three one-dimensional arrays names price, amount, and total. Each array should be capable of holding 10 elements. Using a loop, input values for the price and amount arrays. The entries in the total array should be the product of the corresponding values in the price and amount arrays. After all the data have been entered, display the following output:
Total Price Amount
==== ==== ======
Under each column heading display the appropriate value.
I know how to display everything using printf, how to create the actual arrays and define the array size, but I am confused on how and what loop to use and how to construct it. This is what I have managed to write up so far:
import java.util.Scanner; // Imports the Scanner class import java.text.DecimalFormat; // Imports the DecimalFormat class
public class Prices { public static void main(String [] args) { double[] price = new double[10]; double[] amount = new double[10]; double[] total = new double[10];
// Create a new Scanner object Scanner keyboard = new Scanner(System.in); } //End of main method } // End of public class
Write a program which request two weight in kilograms and grams and print the sum of the weight, if the weight are 3kg 500g and 4kg 700g, your program should print 8kg 200g. this is what i have
Scanner input = new Scanner (System.in); double weight, kg, g; int sum; System.out.println("Please enter weight"); weight = input.nextDouble();
I am trying to create a game in java for my final project for schhol but am having problems with my jframe. I want my 3 Jbuttons to be in the center of the jframe and be vertical but can not seem to get the 3 buttons in the center of the jframe ....
import javax.swing.*; import java.awt.Container; import java.awt.*; public class SnakeObject extends JFrame { public SnakeObject() { createframe();
write a program which request two weight in kilograms and grams and print the sum of the weight, if the weight are 3kg 500g and 4kg 700g, the program should print 8kg 200. this is what I have so far and there is an error that I can't see:
Scanner input = new Scanner (System.in); double weight, kg, grams; int sum; System.out.println("Please enter weight"); weight = input.nextDouble();
[Code] ....
um = (3kg5oog + 4kg700g)-(this line here is where the error is, it supposed to sum the two statement and print out 8kg 200g but i keep getting the red line, dont know where the error is, dont know if it is the coding or what, where error is, where the coding is not right, I am totally lost here right now, this is the if statement.
I have to write a program to calculate my weight on different planets and to do that, I have to read in the surface gravity of all the planets from a file using a separate method from main
public static double[] readGravity() throws IOException { double[] surfaceGravity = new double[8]; Scanner readFile = new Scanner("gravity1.txt"); int i = 0; while (readFile.hasNext()) { surfaceGravity[i] = readFile.nextDouble(); i++; } return surfaceGravity; }
I get this message in the while loop when I try to run the program:
java.util.InputMismatchException; null (in java.util.Scanner)
I'm using the Spring Layout Manager to put a form in a JPanel and I'm trying to center the lines horizontally so they will stay centered when the window is resized. Nothing I've tried has worked, I can't find anything on the web, and even my fallback of seeing how Netbeans does it fails as Netbeans doesn't seem to support the Spring Layout.
Java Code: public class PrintHoledRectangle { public static void main(String[] args) { int width = Integer.parseInt(args[0]) / 2 * 2 + 1; int height = Integer.parseInt(args[1]) / 2 * 2 + 1; int centre = width * height / 2 + 1; int index = 0;
[Code] ....
The width of the rectangle to be printed is given by the first argument, the height by the second
The centre tile ("[_]") of the rectangle (to be printed as " ") is given by the formula: ((width*height)/2)+1, assuming you count each tile left-to-right, top-to-bottom
My thinking is that the programme keeps a running count (seen as 'index') so that, when the centre tile is to be printed, it outputs " ", otherwise "[_]", hence the if-else statement
Normally, the height of the CENTER component (or position) is greater than that of the NORTH and SOUTH components in a BorderLayout.
Is it possible to increase the size of the SOUTH component and decrease the size of the CENTER position because the jcomponents I want to add in the SOUTH component are bigger? or shall I have to change the layout and use some other layout?
In the documentation of StackPane i read: "The stackpane will attempt to resize each child to fill its content area. If the child could not be sized to fill the stackpane (either because it was not resizable or its max size prevented it) then it will be aligned within the area using the alignment property, which defaults to Pos.CENTER."
But as I add another Pane (Anchor- or BorderPane) this added Pane is shows always in left upper corner of the StackPane. How could I force my StackPane to center another AnchorPane?
A stored function to calculate delivery charges given city and weight.

The goal is to desplays circles (max of 30) of fixed radius = 20, with the rightmost circle drawn in blue and left most circle in red and the rest are in white. The center is determined by the location of the point where the mouse is pressed. the number of circles is equivalent to number of mouse has been pressed_ the circles will be drawn only when you push the "draw" button.
import javax.swing.*; import java.awt.*; import java.awt.event.*; import java.util.*; import javax.swing.JPanel; public class CirclePanel extends JPanel { private final int WIDTH = 500, HEIGHT = 300; private final int RDIUS = 20; private final int MAX = 30;
Write a program that draws 20 circles, with the radius and location of each circle determined at random...... Two circles overlap if the distance between their center points is less than the sum of their radii...
There may be many problems with the code in general but what I'm struggling with is the distance and the totalradius portion. Visually, its inaccurate.
import java.awt.*; import javax.swing.*; public class CircleTest extends JPanel { Circle []circles; Circle []circleCenter; Circle []all; private int distance, totalradius, dx, dy; private int radius,x,y;
