Write a class encapsulating the concept of a corporate name (for example, IBM), assuming a corporate name has the following attribute: the corporate name. Include a constructor, the accessors and mutators, and methods toString() and equals(). Also include and method that returns a potential domain name by adding a www. at the beginning and .com at the end of the corporate name (for instance, if the corporate name is IBM, that method should return www.ibm.com). Write a client class to test all the methods in your class.

Complete Answer Must Compile in Visual Code in template Form Code, Must Reflect in UI.

1.            Add a new text box - Mavenlink Project Name

2.            Once we enter project name and project code , on tab change Mavenlink Project Name should be set as

Project Code - Project Name

Example :

Project Code =   T1002

Project Name =   TEST123

So in this case Mavenlink Project Name will be T1002 - TEST123

Use your creativity to make a Novelty Name Generator of your choice, ie: Spooky Halloween Names, Christmas Elf Names, Anything that is school appropriate.

To create the novelty name you should use at least 2 associative arrays.

The page design is up to you. For example:

  • you may use the student name list from last week and create an array of names with their novelty names and display all
  • you may use a button to randomly select a name from the student name list and display their novelty name
  • you may use a form to allow the user to enter their name and then generate and display their novelty name
  • you may think a method other than these. . .

C++ : Write a program that creates a login name for a user, given the user's first name, last name, and a four-digit integer as input. Output the login name, which is made up of the first five letters of the last name, followed by the first letter of the first name, and then the last two digits of the number (use the % operator). If the last name has less than five letters, then use all letters of the last name.

Hint: Use the to_string() function to convert numerical data to a string.

#include <iostream>
#include <string>
using namespace std;

int main() {
   string login;
   string first;
   string last;
   int number;

   /* Type your code here */
  
   return 0;

Using Java

Summary

Create a Loan class, instantiate and write several Loan objects to a file, read them back in, and format a report.

Project Description

You’ll read and write files containing objects of the Loan class. Here are the details of that class:

Instance Variables: customer name (String)
annual interest percentage (double)
number of years (int)
loan amount (double)
loan date (String)
monthly payment (double)
total payments (double)

Methods:

  • getters for all instance variables
  • setters for all instance variables except monthly payment and total payment
  • calculateMonthlyPayment and calculateTotalPayments

The setters for the annual interest percentage, number of years, and loan amount invoke both “calculate…” methods before they exit

The “calculate…” methods compute the named value, then store that amount in the associated instance variable. They are private (helper) methods.

Constructors:

  • a “no-arg” constructor sets the customer name to a default value, the loan date to “no date”, and all numeric variables to zero. This method invokes the “full” constructor
  • a “full” constructor takes the customer name, annual interest percentage, number of years, loan amount, and loan date. It invokes the appropriate setters, but doesn’t need to invoke the “calculate” methods (why?)

Calculations:

monthly interest rate = annual interest percentage / 1200

monthly payment = (loan amount * monthly interest rate) /
(1 – Math.pow( (1 + monthly interest rate), – (number of years * 12) ) )

total loan payments = monthly payment * number of years * 12

* Note: Round all dollar amounts to 2 decimal places

Here is what you should do in main

Use this data to create five Loan objects

                Annual Interest           Loan
  Customer Name   Percentage    Years    Amount   Loan Date
  Bob Smith             6.5%       30   318,000   Sep 1, 2015
  Alicia Herman         4.2%       15   248,000   Oct 15, 2013
  Julie Franciosa       8.5%       10    30,000   Apr 14, 2010

  Frank Larsen          8.9%        5    23,000   Mar 8, 2016

Use this algorithm:

  1. Make the Loan class Serializable (don't forget to import this interface from java.io).
  2. Instantiate Loan objects representing the first three loans above using the “full” constructor
  3. Create an output stream and store the three objects into a binary file using the writeObject method
  4. Instantiate Loan objects representing the last two loans above using the “no-arg” constructor, then use setters to update information about those loans
  5. Append those objects to the output stream created above in step 2
  6. Close the output stream
  7. Create an input stream and read the objects from the binary file above and display in a nicely formatted columnar report
  • Write your code to handle any number of loan objects (i.e., do not assume that there are 5 Loan objects in the file -- use a loop).
  • Include in your report the monthly loan payment and total loan payment amounts
  • Display totals for the amount of the loan amounts, monthly payments, and total loan payments.
  1. Close the input stream

Note: After writing the first three Loan objects to a file (in step 2), close the output stream, then re-open the output stream before step 4 appending the last two Loan objects to the existing file

An example of the output from your program

                    Annual                    Monthly       Total 
    Customer Name   Prcnt  Yrs  Loan-Amount   Payment   Loan Payments   Loan-Date

How Grounded Is Your Love Life?

In a recent experiment, psychologists at University of Pittsburgh and the University of Waterloo in Canada decided to examine stability, turbulence and love. The researchers focused on stability because it is a term that has both literal and abstract meanings. Our bodies can be physically stable or they can be wobbly, and so can our intimate relationships. The study participants were 40 college students who reported being involved in a committed relationship that had lasted for at least a year. The researchers randomly assigned half of their volunteers to sit at a normal desk and the other half to sit at a workstation that had been subtly altered so that both the chair and the desk wiggled slightly. The volunteers individually completed questionnaires about their lives and romantic relationships, including whether they felt the relationship would last. The volunteers were alone in the room when they completed the questionnaire and were instructed to not put their name on the questionnaire. The ratings of perceived stability ranged from 1- 7 (1 = not at all likely to last to 7 = certain this relationship will last). A participant could report any number between 1 and 7 on that scale. The students who had been seated at the unstable workstations were much more likely to perceive instability in their love lives (mean = 4.17) than were the students whose chairs and work spaces didn’t waver (mean = 4.93). There is a statistically significant difference between these means (t(38) = 3.64; p<0.05).
