Java Program That Specifies Three One-dimensional Arrays Names Price / Amount And Total

Dec 2, 2014

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

Calculate Total Price And Display Total In Order Class

Oct 11, 2014

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?

How To Get Total Number Of Pennies In Dollar Amount For The Output Of Total Pay

Mar 28, 2014

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?

Unable To Create A Program For Class Using Two Dimensional Arrays

Dec 6, 2014

I am trying to create a program for class the uses two dimensional arrays. I am stuck on the second step that states Use two parallel arrays. One is a two-dimensional array -- a row of this array will hold six values in this order: [0] number of hours worked, [1] hourly pay rate, [2] gross pay, [3] net pay, [4] federal withholding, and [5] state withholding.

This is what I have so far:

Java Code:

double [][] data = new double [30][6];
String [] names = new String [30];
String str = null;
String detail = null;
int n = input(data, names, inputFile); mh_sh_highlight_all('java');
(there's more but i don't believe it pertains to this question)

My question is how would I create this array. Or, is that right above? I've searched online and in my book and I just don't understand.

Client Class - Cannot Get Total Price To Recognize Surcharge

Apr 26, 2015

I am almost finished with my code. The only hangup I am having is that in my client class, I can't get the total price to recognize a surcharge.

This is my output:
-------------------------------------------------
Your order consists of:

coffee, type mocha, size large, cost: $5.8
tea, flavor earl grey, size medium, cost: $3.6

The total cost of your order is: $8.4
----------------------------------------------------
Notice that the total should be $9.4, rather than $8.4. It is odd because I was able to add a surcharge to my coffee(50 cents), and it does in fact recognize it when calculating the price of the coffee. So why won't my totalPrice in the client class recognize it?

Here is my Client class:

public class CoffeeShop {
public static void main(String[] args)
//One coffee
Coffee coffee = new Coffee(16,"mocha");
coffee.set_price_per_oz(coffee.size);

[Code] ....

Cumulative Sum - Display Total Price From All Loops Added Together

Feb 27, 2014

In the code below, under calculations, I have x=totalPrice+xXxXxX. Obviously the x's were just place holders, but I wanted to know if there was any way to add something there so the program would tally the totalPrice, store it in the x variable outside the loop, so when the loop ended it would display the total price from all the loops added together where I have System.out.println("TOTAL OF ALL ORDERS: $"+ round.format(x)); at the very end.

Java Code:

import java.util.Scanner;
import java.text.DecimalFormat;
public class ModifyOrderV2TEST
{
public static void main(String [] args)
{
//Rounding
DecimalFormat round = new DecimalFormat("0.00");

Baseball Team - Calculate Total Amount Of Home Runs Hit By Batters

Mar 24, 2014

So I have a class called Team that is a collection of players and managers for a baseball team, and one of my required methods is to calculate the total amount of Home Runs hit by the batters. Now along with the Team class I have an abstract Employee class, an abstract Player class and a Batter class that extends the Player class I thought this would be fairly easy but it is coming out to be pretty hard my code is as follow:

class Team {
public int _numPitcher;
public int _numBatter;
public String _manager;
public ArrayList<Player> team;
 
[Code] ....

The total salary works awesome but for some reason when I try and call up how many home runs a player has it wont call correctly I get this red line under my code that says: The method getHomeRuns() is undefined for type Player. I am trying to call this from the batter class which is an extension of the Player class...

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.

Students Grading - Two Dimensional Arrays

Jun 18, 2014

I have the program bellow that grades students(based on a two dimensional array with the answers) and i need to make it display the students based on the grades/scores in ascending order . I did that in two ways (using a array and a two dimensional array) but i have a hunch it can be done much more simple then i did it (but still using array object and nothing else ) .

public class GradeExam {
/** Main method */
public static void main(String args[]) {
// Students' answers to the questions
char[][] answers = {

[code]....

My first solution creating an array with the grades for sorting :

public class C8_3 {
public static void main(String args[]) {
// Students' answers to the questions
char[][] answers = {
{'A', 'B', 'A', 'C', 'C', 'D', 'E', 'E', 'A', 'D'},
{'D', 'B', 'A', 'B', 'C', 'A', 'E', 'E', 'A', 'D'},

[code]....

2D-dimensional Arrays Of Object Types

Dec 8, 2014

I need to write a class that represents and image of RGB pixels. This class uses a two-dimensional array of object type that represents R,G and B values.

When I compile the class it completes successfully. However, when I try running a "tester" class , I'm encountering errors in a few methods. I've been trying it out for 2 days now, but unsuccessfully thus far..Those method are : rotating the image by 90 degrees clockwise (and vice versa , but I just use clockwise method 3 times for that) , shifting the image sideways, and shifting the image up/down..

I've attached the whole source code for the class , and the list of errors I get when I try to run my tester. URL...

Using Two Dimensional Arrays To Make Calculations

May 10, 2014

I am having problems figuring out how to make calculations using a two dimensional array. The problem is finding the distance of a projectile given the launch velocity and angle. The equation is x = v^2*sin(2theta)/g. I understand how to implement this equation using the toRadians() and Sin() methods. What I don't understand is how to calculate the distance values with a multi dimensional array.

double [][] data = { {20, 15},
{50, 35},
{80, 45},
{100, 65},
{150, 85},
{10, 50},
{110, 8}};

My array has the velocities on the left and angles on the right. I tried using nested loops but I don't know how to access the two pieces of data at a time which I need.

Java Program That Keeps Track Of People Names

Jan 13, 2015

I need to make a program that keeps track of peoples names, allows you to add a note to each name and preferably would reorganize whatever you put in by date or by spelling. (I suppose the phonebook application in cell phones is a good match, a supermarket's list of foods and prices would work as well).

Process Data And Determine Winners - Two Dimensional Arrays

Feb 4, 2015

The international Olympics Committee has asked you to write a program to process the data and determine the medal winners for the pairs figure skating. You will be given the following file: Pairs.txt

Which contains the data for each pair of skaters. The data consists of each skater's name, their country and the score from each of eight judges on the technical aspects and on the performance aspects. A typical record would be as follows:

Smith
Jones
Australia
5.0 4.9 5.1 5.2 5.0 5.1 5.2 4.8
4.3 4.7 4.8 4.9 4.6 4.8 4.9 4.5

The final score for each skater is the sum of the average of the two categories of score. Design a class to hold the above data and the final score. Read the data in from the file and calculate the final score for each pair. Sort the array of objects , and display the results on the screen in order, giving special prominence to the medal winners.

Here is my CLass:

public class Skaters {
private String name1;
private String name2;
private String country;
private double [] arrTech = new double [8];
private double [] arrArt = new double [8];
private double score;

[code]...

how do i print my 2 arrays using the file? i got the name1, name2 and counntry to print but im stuck on printing the scores that are stored in the arrays. Also, i have to print the average for each array. one is for techniques and the other one is artistic. as you can see i already wrote the code for it but im stuck in printing it.

Write Java Program That Asks User For List Of Names?

May 21, 2015

I am trying to write a java program that asks the user for a list of names (one per line) until the user enters a blank line. At that point the program should print out the list of names entered, where each name is listed only once (i.e., uniquely) no matter how many times the user entered the name in the program. I am supposed to use an ArrayList for this problem.

My idea for a solution is to create an ArrayList<String>, read each name, i.e., line, entered and then to see if that name is already in the ArrayList. I created a for loop to check each element in the ArrayList but when I try to assign an element to a string variable I get the error "Type mismatch: cannot convert from Object to String". Not sure why that is happening because the ArrayList is defined as a String list.

Here is the code so far.

/*
* File: UniqueNames.java
*/
import acm.program.*;
import java.util.*;

[Code].....

Using Parallel Arrays To Store Names And Job Titles Then Display Combo Depending On Input

Dec 24, 2014

I am trying to use parallel arrays to store names and job titles, then display the name/job title combo depending on which is entered. I have always struggled with arrays, so I'm sure that's where my issue is, but I am not sure how to resolve this one. I tried to use the toString() method with the jobs to see if that would allow the job title to match to one of the titles listed, and I tried to not use the toString() method with the names to see if that would allow the name entered to match to one of the names listed in the array. Both options only display the "invalid" message no matter what I enter. What would be the best choice to use the arrays to properly display the information ....

import java.util.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
 public class JEmployeeTitle2 extends JApplet implements ActionListener

Create A Program That Calculate Price Of Carpeting For Rectangle Rooms

Apr 23, 2014

I am not getting any syntax errors but the program simply does nothing when I run it.

I literally just get "run: BUILD SUCCESSFUL (total time: 3 seconds)".

So basically, I need to create a program that calculates the price of carpeting for rectangle rooms.(multiply the area of the floor by the price per square foot of the carpet).

-The RoomDimension class should have two fields: one for length and one for width, and a method that returns the area of the room
-The RoomCarpet class that has a RoomDimension object as a field, a field for the cost of carpet per square foot, and a method that returns the total cost of the carpet

Here is what I have:

package roomdimension.java;
public class RoomDimension {

private double length=0;
private double width=0;
private final double area = length * width;

public void RoomDimension(double len, double w)

[Code] ....
