prepare a driver program named DiceGame that plays a simple dice game between the computer and the user. When the program runs, a loop should repeat 100 times. Use a for loop for this. Each iteration of the loop should do the following:
• Generate a random integer in the range of 1 through 6. This is the value of the computer's roll. See Ex3DiceRoll.java that I included in my module 2 programs for information on how to do this.
• Generate another random integer in the range of 1 through 6. This is the value of the user's dice.
• The die with the highest value wins. (In case of a tie, there is no winner for that particular roll of the dice.)
As the loop iterates, the program should keep count of the number of times the computer wins, the number of times that the user wins, and the number of ties. After the loop performs all if its iterations, the program should display who was the grand winner, the computer or the user and how times each won as well as the number of ties.
To do: prepare a driver program named GuessingGame that generates a random number between 1 and 20. Asks the user to guess the value of the number. If the user's guess is higher than the random number, the program should display "Your guess was high, guess again". If the user's guess is lower than the random number, the program should display "Your guess was low, guess again". The program should use a loop that repeats until the user correctly guesses the random number and should also keep track of how many times it takes to guess correctly. (Get this much running first!). Then add the following. After the number has been guessed, the program should ask the user if they want to play again. If they answer yes, the process should start over again.
To do: A sales person gets a base salary of $200. They also get 3% of any sales between 500 and $1000 and 5% of any sales over $1000. prepare a driver program named Commission.java that takes in the amount of sales as input and outputs the total amount earned (the base salary plus commission). Make certain the output looks like money. Include a sentinel controlled loop that ends when you type in -999 for the sales. Also keep track of the total amount of money for all salespeople and how many total sales people there are (a counter and an accumulator).
To do: prepare a driver class program called Sales.java that loops to find out a sales receipt. The loop ends if the user types in "no" when asked if there are more items. Within the loop, the input should be the name of the item, the price each and how many were purchased. Inside the loop, output the name of the item and the cost for that item (price times number purchased). Keep two accumulators and a counter. The first accumulator will accumulate the total sales. The second accumulator will keep track of the total number of items purchased and the counter will keep track of the number of sales made (how many times the program loops).
After you complete the loop,
a) print out the total sales. Then add a 3.25% sales tax and print out the amount of tax and the total sales including the tax.
b) print out the number of different purchases were made and
c) print out the total number of items purchased
Something like "The cost of your purchase was $453.00 plus $14.72 in sales tax for a total of $467.72. You purchase five different items and a total of 14 units").
To do: prepare a program named Bill.java. The instance variables should be serverName, amount, taxAmt, and tipAmt. You need the following methods (this is called a UML diagram - more about them in module 4). Assume 6.75% tax.
Use the following main method in your driver program.
public class BillDriver {
public static void main(String[] args) {
Bill bill1 = new Bill("Sam", 50.00, 50.00*.0675,10.00);
Bill bill2 = new Bill();
System.out.println(bill1.toString());
System.out.println(bill2.toString());
bill2.setServerName("Suzie");
bill2.setAmount(70.00);
bill2.calcTax();
bill2.setTipAmt(15.00);
System.out.println(bill2.toString());
}
}
The output should be
Sam collected $50.00 with a tip of $10.00 and a tax of $3.38
null collected $0.00 with a tip of $0.00 and a tax of $0.00
Suzie collected $70.00 with a tip of $15.00 and a tax of $4.73
