Description

Write a program that will determine whether the user passed or failed a test. The program will ask the user to input the following:

Maximum Test Score - the maximum total scores in the test.

Percent Pass Score - the minimum percent scores required to pass the test.

User Test Score - the actual scores obtained by the user in the test.

From the above input values, the program will compute the user percent score. It will compare the percent user score with the percent pass score. If the percent user score is equal to or greater than the percent pass score, the program will consider the user having passed the test. Otherwise, the program will consider the user having failed the test. At the end, the program will display the result summary. See the Test section below.

Problem Description:
(The Account class) Design a class named Account that contains:
A private int data field named id for the account (default 0).
A private double data field named balance for the account (default 0).
A private double data field named annualInterestRate that stores the current interest rate (default 0). Assume all accounts have the same interest rate.
A private Date data field named dateCreated that stores the date when the account was created.
A no-arg constructor that creates a default account.
A constructor that creates an account with the specified id and initial balance.
The accessor and mutator methods for id, balance, and annualInterestRate.
The accessor method for dateCreated.
A method named getMonthlyInterestRate() that returns the monthly interest rate.
A method named withdraw that withdraws a specified amount from the account.
A method named deposit that deposits a specified amount to the account.

Draw the UML diagram for the class. Implement the class. Write a test program that creates an Account object with an account ID of 1122, a balance of $20,000, and an annual interest rate of 4.5%. Use the withdraw method to withdraw $2,500, use the deposit method to deposit $3,000, and print the balance, the monthly interest, and the date when this account was created.

Analysis:
(Describe the problem including input and output in your own words.)

Design:
(Draw an UML class diagram for the Account class.)

Coding: (Copy and Paste Source Code here. Format your code using Courier 10pts)

public class Test {
public static void main (String[] args) {
Account account = new Account(1122, 20000);
Account.setAnnualInterestRate(4.5);
  
account.withdraw(2500);
account.deposit(3000);
System.out.println("Balance is " + account.getBalance());
System.out.println("Monthly interest is " +
account.getMonthlyInterest());
System.out.println("This account was created at " +
account.getDateCreated());

The program prompts a user for the number of contestants entered in this year’s and last year’s Greenville Idol competition, and then it displays the revenue expected for this year’s competition if each contestant pays a $25 entrance fee.

The programs also display a statement that compares the number of contestants each year. Now, replace that statement with one of the following messages:

• If the competition has more than twice as many contestants as last year, display The competition is more than twice as big this year!

• If the competition is bigger than last year’s but not more than twice as big, display The competition is bigger than ever!

• If the competition is smaller than last year’s, display, A tighter race this year! Come out and cast your vote!

Below is the source code.

using System;
using static System.Console;
class GreenvilleRevenue
{
   static void Main()
   {
      const int ENTRANCE_FEE = 25;
      string entryString;
      int numThisYear;
      int numLastYear;
      int revenue;
      bool isThisYearGreater;
      Write("Enter number of contestants last year >> ");
      entryString = ReadLine();
      numLastYear = Convert.ToInt32(entryString);
      Write("Enter number of contestants this year >> ");
      entryString = ReadLine();
      numThisYear = Convert.ToInt32(entryString);
      revenue = numThisYear * ENTRANCE_FEE;
      isThisYearGreater = numThisYear > numLastYear;
      WriteLine("Last year's competition had {0} contestants, and this year's has {1} contestants",
         numLastYear, numThisYear);
      WriteLine("Revenue expected this year is {0}", revenue.ToString("C"));
      WriteLine("It is {0} that this year's competition is bigger than last year's.", isThisYearGreater);
   }
}

Please show output and source code of how to get the displayed text.

In this assignment, you are required to write the SQL statements to answer the following queries using PostgreSQL system.

The SQL statements comprising the DDL for Henry Books Database are given to you in two files. For that database, answer the following queries. Create the files Q1 to Q10 in PostgreSQL. Do follow the restrictions stated for individual queries.

1. List the title of each book published by Penguin USA. You are allowed to use only 1 table in any FROM clause.

2. List the title of each book that has the type PSY or whose publisher code is JP. You are allowed to use only one condition term in any WHERE clause; i.e., don't use AND/OR boolean operations.

3. List the title of each book that has the type CMP, HIS, or SCI. You are allowed to use only one condition term in any WHERE clause.

4. List the title of each book written by John Steinbeck and that has the type FIC.

5. For each book, list the title (sorted alphabetically), publisher code, type and author names (in the order listed on the cover).

6. How many book copies have a price that is greater than $20 and less than $25?

7. For each publisher, list the publisher name and the number of books published by it, only if the publisher publishes at least 2 books.

8. For each book copy available at the Henry on the Hill branch whose quality is Excellent, list the book's title (sorted alphabetically) and author names (in the order listed on the cover).

9. Create a new table named FictionCopies using the data in the bookCode, title, branchNum, copyNum, quality, and price columns for those books that have the type FIC. You should do this in two steps: 9A) Create the table, and 9B) populate it with the said data.

10. Ray Henry is considering increasing the price of all copies of fiction books whose quality is Excellent by 10%. To determine the new prices, list the bookCode, title, and increased price of every book in Excellent condition in the FictionCopies table. You are not allowed to modify the prices in the table, just show them.

Using draw.io diagram tool, design a database schema for an application that tracks and manages students’ applications for a university. Make sure to create proper primary key for each entity. Add relations and specify cardinalities.

• All entities and attributes must be named using the underscore convention. Highlight primary keys in red
• List any assumptions you have made

• Use diamonds and the association on the arrow.

• THINGS TO KEEP IN MIND :

• The university needs to keep track of students’ application. The application contains information about student: name, address, phone number, DOB, SSN, and generate a unique ID for each student.
• Education records has to be submitted as well. The education records contain information about previous degrees, GPA, name of school attended and dates ( from – to dates)
• Test scores are also submitted along with applications. The student can submit more than one test score. The test score consist of test type, date and score.
• The student should also specify which major they are applying to, for what term
• The university assign one employee from the admission office to process the application. The employee will handle multiple application at the same time.
• Applications can be submitted to different departments.
