Computer Science Homework Help

Question 1:

Write a method squareOfSymbols that displays a solid rectangle of symbols whose height

and

width are specified in integer parameter height and width respectively. And this method also

receive a third parameter of type char called fillCharacter. For example, if height is 5, weight is

4, and the fillCharacter is *, the method should display

****

****

****

****

****

Incorporate this method into an application that reads an integer value for side from the user

and outputs the asterisks with the squareOfAsterisks method.

Question 2:

Write methods that accomplish each of the following tasks:

A. Write a method called divideQuotient that calculates the integer part of the quotient when

integer a is divided by integer b.

B. Write a method called divideRemainder that calculates the integer remainder when integer

a is divided by integer b.

C. Use the methods developed in parts (a) and (b) to write a method displayDigits that

receives an integer between 1 and 99999 and displays it as a sequence of digits, separating

each digit by two spaces. For example, the integer 4562 should appear as 4 5 6 2

D. Also write a method called displayReverseDigits that is similar to (c), but it displays digits in

reverse order. For example, 2 6 5 4

Incorporate the methods into an application that inputs an integer and calls displayDigits by

passing the method the integer entered. Display the results.

Question 3:

Write an application that simulates coin tossing. Let the program toss a coin each time the user

chooses the “Toss Coin” menu option. Count the number of times each side of the coin appears.

Display the results. The program should call a separate method flip that takes no arguments

and returns a value from a Coin enum (HEADS and TAILS). [Note: If the program realistically

simulates coin tossing, each side of the coin should appear approximately half the time.]
