Present Value
Suppose you want to deposit a certain amount of money into a savings account and then leave it alone to draw interest for the next 10 years. At the end of 10 years you would like to have $10,000 in the account. How much do you need to deposit today to make that happen? You can use the following formula, which is known as the present-value formula, to find out:
The terms in the formula are as follows:
- P is the present value, or the amount that you need to deposit today.
- F is the future value that you want in the account. (In this case, F is $10,000.)
- r is the annual interest rate.
- n is the number of years that you plan to let the money sit in the account.
Write a method named PresentValue that performs this calculation. The method should accept the future value, annual interest rate, and number of years as arguments. It should return the present value, which is the amount that you need to deposit today. Demonstrate the method in an application that lets the user experiment with different values for the formula’s terms.

Salary Calculator
Create a program that computes the salary based on an employee's hourly wage and hours worked. Note that employees may work for fractions of an hour, e.g. 1 and a half hours (1.5 hours). Use the following formulas:
Less than or equal to 40 hours worked
hourly wage * hours worked
Over 40, but less than or equal to 65 hours worked
(hourly wage * 40) + (hours worked - 40) * (hourly wage * 1.5)
Over 65 hours worked
(hourly wage * 40) + (hourly wage * 1.5) * 25 + (hours worked - 65) * hourly wage * 2
Also make sure that the hourly wage and hours worked are positive. Otherwise, display the error message: "Invalid input".
Please see the sample outputs below to guide the design of your program.

3. The formula for determining compound interest is:
A represents the amount to earn; P is the principle that is initially invested; r is the interest rate earned; n is the number of times the interest is compounded; and t is the number of time periods for the investment. Write a program that prompts the user to enter P, r, n and t. The program should output the amount earned on the investment. 4. Look up the Pythagorean theorem if you are not already familiar with it. Use the following formula to solve for c in the formula: c = √a2 + b2. Use the proper functions from the cmath header file. Be sure to output the result.l

Each player chooses a secret code of 4 digits from 0 – 9. The digits must be all different. The goal of the game is for each player to guess the other player's secret code. The players in turn present their guesses to the opponents. The opponents respond by telling the players: 1. The number of bulls, i.e. the number of matching digits in their right positions, and 2. The number of cows, i.e. the number of matching digits but in different positions. ### Requirements The main goal of this assignment is to develop the bulls and cows game that allows a single player to play interactively against the computer. The game stores two secret codes, one from the player and one from the computer. The player and the computer will try to guess each other’s secret code. Both the player and the computer only have seven attempts for guessing the secret code. If the player enters invalid…arrow_forward
- (Geometry: great circle distance) The great circle distance is the distance between two points on the surface of a sphere. Let (x1, y1) and (x2, y2) be the geographi- cal latitude and longitude of two points. The great circle distance between the two points can be computed using the following formula: d = radius * arccos(sin(x1) * sin(x2) + cos(x1) * cos(x2) * cos(y1 - y2)) Write a program that prompts the user to enter the latitude and longitude of two points on the earth in degrees and displays its great circle distance. The average earth radius is 6,378.1 km. The latitude and longitude degrees in the formula are for north and west. Use negative to indicate south and east degrees.arrow_forwardCredit Card Number Check. The last digit of a credit card number is the check digit, which protects against transcription errors such as an error in a single digit or switching two digits. The following method is used to verify actual credit card numbers but, for simplicity, we will describe it for numbers with 8 digits instead of 16:• Starting from the rightmost digit, form the sum of every other digit. For example, if thecredit card number is 4358 9795, then you form the sum 5 + 7 + 8 + 3 = 23.• Double each of the digits that were not included in the preceding step. Add all digits ofthe resulting numbers. For example, with the number given above, doubling the digits,starting with the next-to-last one, yields 18 18 10 8. Adding all digits in these valuesyields 1 + 8 + 1 + 8 + 1 + 0 + 8 = 27.• Add the sums of the two preceding steps. If the last digit of the result is 0, the number isvalid.

- When you borrow money to buy a house, a car, or for some other purposes, then you typically repay it by making periodic payments. Suppose that the loan amount is L, r is the interest rate per year, m is the number of payments in a year, and the loan is for t years. Suppose that i = (r / m) and r is in decimal. Then the periodic payment is: You can also calculate the unpaid loan balance after making certain payments. For example, the unpaid balance after making k payments is: where R is the periodic payment. (Note that if the payments are monthly, then m = 12.) Instructions Write a program that prompts the user to input the values of L, r, m, t, and k. The program then outputs the appropriate values. Your program must contain at least two functions, with appropriate parameters, to calculate the periodic payments and the unpaid balance after certain payments. Make the program menu driven and use a loop so that the user can repeat the program for different values.

In each trial your program should generate a newrandom number. If user guess at least twice correctly, then shows the message, “you won by 2-1” and vice versa for losing.When game is over, ask the user to play again: If the user types "yes", the game start again.else stop the game.arrow_forward
- Im working on homework and am stuck. I have created the code for taking the input of the user but I am not sure how to separate them to find how many are left. The program must compute the number of terms a student has remaining, and this should be an integer. For example, if a student has 15 courses remaining and plans to take 2 a term then they need 8 terms to complete the courses. In other words, you can’t have 7.5 terms because the student must attend an entire term. import java.util.Scanner; import java.util.Arrays; public class MainClass { public static void main(String[] args) { Scanner input = new Scanner(System.in); int[][] students = new int [10][2]; for(int i = 0; i < 10; i++) { for(int j = 0; j < 2; j++) { students[i][j] = input.nextInt(); } } int grades = 0; System.out.print("Enter number of courses student has left to graduate and how many courses they plan to take each term: "); int Student1 = input.nextInt(); System.out.print("Enter number of courses…arrow_forward(Calculating Credit Limits) Collecting money becomes increasingly difficult during periods of recession, so companies may tighten their credit limits to prevent their accounts receivable(money owed to them) from becoming too large. In response to a prolonged recession, one companyhas cut its customers’ credit limits in half. Thus, if a particular customer had a credit limit of $2000,it’s now $1000. If a customer had a credit limit of $5000, it’s now $2500. Write a program thatanalyzes the credit status of three customers of this company. For each customer you’re given:a) The customer’s account number.b) The customer’s credit limit before the recession.c) The customer’s current balance (i.e., the amount the customer owes the company).Your program should calculate and print the new credit limit for each customer and shoulddetermine (and print) which customers have current balances that exceed their new credit limits.arrow_forwardIt's important to know how to best utilize the super keyword.arrow_forward
