Counting Total Number Of Searches - Calling Price Method
Apr 23, 2015
How would I program a counter that will return the total number of search, failed searches and correct searches. The second thing is how can a return the price of the search methods with out calling for it specifically. Here is my current code.
package stu.paston.program7;
import java.util.Scanner;
public class MainClass
{
public static void main(String[] args)
{
InventoryClass productData= new InventoryClass();
[Code] ....

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 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] ....

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");

Why is my program not calculating the total and average of the price of the items and not printing it out?
Java Code:
/*

package assignment4;

It prints out everything but the total of the items and I dont know why. :(

How can I do the work below in Java
In this main class, create 5 objects of the class Menu, as defined in the table below.
Name amount of calories cooking time price per person number of drinks
Fufu and Groundnut Soup 564.65 2515.572
Red Red 345 12 9.980

Ga Kenkey and Fish 780 10 10.15 1
Banku and Tilapia 450.4 35 25.17 2
Exercise d
In your main class create an array of length 5, and store the 5 objects (Exercise c) into the array. You can use any name for your array.
From the array, use a loop to: Print the details of all the objects using the method you defined in Exercise b.
Exercise e
Use another loop to:
-Print only the name and cooking time of all the dishes that take less than 30 minutes to cook. Hint: you may use the getter methods for the name and cooking time attributes, and then, print these values (name, cooking time).
Exercise f
Use another loop to :
-Calculate and print the total price of all the objects (in the array).
-Calculate the total price of all the objects with VAT included for each dish (VAT rate is 17.5%).
Submission
-Create a folder with your index number as its name.
-Copy your Java Project folder into the created folder.
-Print a hard copy of your classes.
-Submit both soft copy and hard copy of your project

I am currently trying to roll 5 dice 100,000 times and output the number of times each possible total (of dots/pips) occurs. It seems to output the incorrect thing and isnt counting the occurrences properly.
public class lab_DiceRollTest {

int total;
int total2;
String valid;
String isDifferent;
int rolls = 100000;

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

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?

The method public static int steps(int posts, int stride) calculates how many strides can be taken to get back to posts. Let's say if the method is (12, 4), it takes only three steps. Now let's say the method has parameters (12,5), so it should be (5, 10, 3, 8, 1, 6, 11, 4, 9, 2, 7, 12). My method works for such examplse as (12, 4) or (12,3) or (6,2)... but how can I figure out (12,5)?
Java Code:
public static int steps(int posts, int stride) {
int countSteps = 0;
int result = 0;
do {
result += stride;

I tried the following code, OK:
Java Code:
String temp = "hi this sf hello is new what is this";
String[] cmd = temp.split("s");
int num = cmd.length;
System.out.println("number of words are: "+num); mh_sh_highlight_all('java');
However, when i get the input from user , i didnt get the expected result:
Java Code:
System.out.println("Enter the input string to count the words: ");
String[] cmd = new Scanner(System.in).next().trim().split("s");
int num = cmd.length;
System.out.println("number of words are: "+num); mh_sh_highlight_all('java');
Now Result for above code:
Enter the string to count the words:
hi this is new
words are: 1

I need to modify modules used in the book that run a bubble sort, selection sort, and insertion sort on an integer array such that each module keeps a count of the number of swaps it makes.
How do I code for this?
Then we have to design an application that uses 3 identical arrays of at least 20 integers. That calls each module on a different array, and display the number swaps made by each algorithm.

I have to write a program that will read a picture and then print out the number of blocks inside it.
I have to read the picture as a binary matrix of the size r - c (number of rows times number of columns). The blocks are groups of one or more adjacent elements with the value 1.
- Blocks are built exclusively of elements with value 1
- Each element with value 1 is a part of some block
- Adjacent elements with value 1 belong to the same molecule.
We only take into account the horizontal and vertical adjacency but not diagonal.
INPUT:
In the first line of the input we have the integers r and c, separated with one space.
Then we have the r lines, where each contains s 0's and 1's.
The numbers inside the individual lines are NOT separated by spaces.
The OUTPUT only print the number of blocks in the picture.
Example:
INPUT:
7 5
01000
00010
00000
10000
01000
00001
00100
OUTPUT:
6
THIS IS WHAT I CAME UP SO FAR:
import java.util.Scanner;
class Blocks{
public static void main(String[] args){
Scanner sc=new Scanner(System.in);
char ch[][];
int rowNum=sc.nextInt();
int columnNum=sc.nextInt();
