Java How to Program Exercise 4.11
Explain what happens when a Java program attempts to divide one integer by another. What happens to the fractional part of the calculation? How can you avoid that outcome?

My instructor want me to do that exercise with these details and I am so confuse. I don't know where to start.
"Random number of Trips"
"Enter gallon and miles as whole numbers"
"NPG decimal number"

In a few paragraphs what are the pros and cons on the usefulness of open source projects. Specifically speaking about QA

- What IT function impacts user satisfaction the most?

What would you do to ensure high user satisfaction?

Java

Write a program that reads 4 integer numbers from the user combine it into a single number. You need to ask the user to first specify how to combine the numbers (forward or backward). Note that for the backward option you need to check that the last digits should be 0, also for the forward option you need to check that the fist digit is not 0. Use for loops and switch for the menu.                       4. Write an application that prompts the user to enter an integer limit and then print the numbers from 1 to this limit in the following format. The number read should not be greater than 10 and should not be negative.        Enter a number: 3 Enter a number: 6 Enter a number: 2 Enter a number: 0 1.Forward 2.Backward Choose an option: 1 The number is 3620 Enter a number: 3 Enter a number: 6 Enter a number: 2 Enter a number: 0 3.Forward 4.Backward Choose an option: 2 Error!

Create your own function in C that accepts one input number and returns a double number. The themes for the functions should be one of the following: Calculates 3.14 times of the square of input number. For example, if 2 is input then 12.56 should be returned. (e.g. 3.14*2*2 = 12.56)

The solution should be written in Java.

Your POSmain program should take three file names from command line arguments. The first file contains a list of products and their prices; the second and third files are lists of items in two shopping carts of two customers. The POSmain program should first read the price file, then read each of the cart files to load a list of items in a shopping cart and store them in a ShoppingCart objects. The price file may contain a variable number of products and the cart files may contain a variable number of items.
POSmain then will create a CashRegister object by passing the price list to it. The POSmain program then will use the CashRegister object to scan items in a cart and print a receipt for each shopping cart one by one. At last, POSmain will use the CashRegister object to print a report for the day.
The students of CSIT111 and CSIT811 will print a different report for the day, which requires different design of your CashRegister class.

The output should be like this:-

One customer is checking out ...

What is the PID for xeyes?

Create a Java program with a method that searches an integer array for a specified integer value **(see help with starting the method header below). If the array contains the specified integer, the method should return its index in the array. If not, the method should throw an Exception stating "Element not found in array" and end gracefully. Test the method in main with an array that you make and with user input for the "needle".

starting header

**

public static int returnIndex(int[ ] haystack, int needle) {

Code should be written in C

Use pointer variables for parameter passing, where appropriate and pointer arithmetic when working with arrays.

1) Using initialization lists, create 5 one-dimensional arrays, one for each of these:

• hold the names of the people running in the election
• hold the names of the subdivision
• hold the vote counts in the Brampton subdivision for each candidate
• hold the vote counts in the Pickering subdivision for each candidate
• hold the vote counts in the Markham subdivision for each candidate

Use the data from the example below.

* Your C program should take the data in the arrays and produce the output below, neatly formatted as shown:

Candidates                            Subdivisions                 Totals

                             Brampton  Pickering Markham        

Aubrey                     600            800          800            2200

Blake 700            700          600            2000

Chubbs 800           700          800           etc

Oliver 400            450         300             

Zamier 900            900       900            

Totals                     3400            etc                              etc

1. Create a function that will find the total votes in one subdivision and return that to main( ). Call this function 3 times to produce the 3 totals in the last line of output.
2. Create a function that will find the total votes for one candidate and return that to main( ). Call this function 5 times to produce the 5 totals in the last column of output. Be very careful with the parameter list here. Send the function only the information it needs.
3. Create a function that will output the first 2 lines of headings.

Consider the computer attacks in the previous chapters. How would a VPN protect a user from one or more of them?

Starting a Family Video, This is an SQL Assingment

Each family video has a store number, a street address, city, state, zipcode, and phone number. Each store will have a number of employees. Each staff member should have an employee number, name, salary, phone number. Each store should have a single employee that is the manager for that store.

assume that every DVD is a movie. Every movie will have a title and a single category (Action, Drama, Horrow, SciFi, etc.). Any given store will have any number of DVD copies of a movie. The rental cost is set for the movie and is the same across all stores.

Family Video track of all borrowers (borrower number,name, phone number). A borrower is allowed to rent from any store, and may rent any number of items, but each rented item must record the day it was rented and its return date.
