Problem: HugeIntegerClass

Create a class HugeInteger which uses a 40-element array of digits to store integers as large as 40 digits each. Provide methods Input, toString, Add, and Subtract. For comparing HugeInteger objects, provide the following methods: IsEqualTo, IsNotEqualTo, IsGreaterThan, IsLessThan, IsGreaterThanOrEqualTo and IsLessThanOrEqualTo. Each of these is a method that returns true if the relationship holds between the two HugeInteger objects and returns false if the relationship does not hold. Provide method IsZero. In the Input method, use the string method toCharArray to convert the input string into an array of characters, then iterate through these characters to create your HugeInteger. If you feel ambitious, provide methods Multiply, Divide, and Remainder

Q1:

Your team is asked to program a self-driving car that reaches its destination with minimum travel time.

Write an algorithm for this car to choose from two possible road trips. You will calculate the travel time of each trip based on the car current speed and the distance to the target destination. Assume that both distances and car speed are given.

Q2:

Write a complete Java program that prints out the following information:

1. Declare String object and a variable to store your name and ID.
2. DisplayYour Name and Student ID.
3. Display Course Name, Code and CRN
4. Replace your first name with your mother / father name.
5. Display it in uppercase letter.

Note:Your program output should look as shown below.

My Name: Ameera Asiri

My student ID: 123456789

My Course Name: Computer Programming

My Course Code: CS140

My Course CRN: 12345

AIYSHA ASIRI

Note : Include the screenshot of the program output as a part of your answer.

Q3:

Write a tester program to test the given class definition.

Create the class named with your id with the main method.

2. Print the characteristics of M1 and M2.
3. Create one mobile M3 using the second constructor.
4. Change the id and brand of the mobile M3. Print the id of M3.

Q4:

Write a method named raiseSalary that accepts two integers as an argument and return its sum multiplied by 15%. Write a tester program to test the method. The class name should be your ID.

Your answer should be supported with a screenshot of the program with output.

Consider f,g:ℤ→ℤ given by:

• f(n) = 2n
• g(n) = n div 2

Which of the following statements are true? Select all that apply

Using SET operations, display a list of customers that are interested in a car (prospect table) of the same make and model which they already own.

Which command do you use to find the process that’s holding a file open?

As a second example, consider the communication paradigm referred to as queued RPC, as introduced in Rover [Joseph et al. 1997]. Rover is a toolkit to support distributed systems programming in mobile environments where participants in communication may become disconnected for periods of time. The system offers the RPC paradigm and hence calls are directed towards a given server (clearly space-coupled). The calls, though, are routed through an intermediary, a queue at the sending side, and are maintained in the queue until the receiver is available. To what extent is this time- uncoupled? Hint: consider the almost philosophical question of whether a recipient that is temporarily unavailable exists at that point in time.

why are direct input and outputs highly discouraged in setters and getters

Sketch! This assignment is to write a Python program that makes use of the OpenGL graphics library to make an interactive sketching program that will allow the user to do line drawings. The user should be able to choose from a palette of colors displayed on the screen. When the user clicks the mouse in the color palette area, the drawing tool will switch to using the color selected, much like dipping a paint brush into a new color of paint.

Here are two starter codes. I'm trying to combine them basically but end up with a mess. It's supposed to be mimicking Microsoft Paint. Pick a color and then draw a line with it. There are 3 boxes on the left side, red, green, and blue. When the user clicks the box the line color matches the color of the box. Then the user can click in the space and free draw a line of that color, similar to Microsoft paint.

Urgent need: please solve this question below:

A description of how your chosen Information Systems Technology is currently being used in different areas of business, government or and/or society. If your technology is being used in many different areas, try and focus on four areas that either have a high impact or that interest your group. Be sure to include the impacts that the technology is having on each of these areas. Your impacts should include both quantitative (e.g., financial, etc.) as well as qualitative (e.g., quality of life, etc.) ones. In addition, describe 3-4 advantages and 3-4 disadvantages of the use of the technology in these areas. For the advantages, you should clearly describe how/why these are advantages, whether or not they are sustainable and why. For the disadvantages, you should clearly describe why they are disadvantages, how serious these disadvantages are and whether or not there are any ways to overcome these disadvantages.

Define an interface called Vehicle, which requires the following methods getName: returns a String getTopSpeed: returns an int getMaxPassengers: returns an int Note that the class Car implements this interface and is preloaded (in one of the following questions you will define this class)

For example:

Test

Vehicle v = new Car("BMW", 280, 5); System.out.println(v.getName()); System.out.println(v.getTopSpeed()); System.out.println(v.getMaxPassengers());

Results :

BMW

280

5

Test 2 :

Vehicle v = new Car("Smart", 150, 2); System.out.println(v.getName()); System.out.println(v.getTopSpeed()); System.out.println(v.getMaxPassengers());

Results :

Smart

150
