Write a simple two players dice game. Each player will take turns to roll a dice. The first player that reach more than 100 points win the game. If the player rolls a 6, the player will score 6 points and has the chance to roll again.

Create a class called Complex for performing arithmetic with complex numbers. Complex numbers have the form realPart + imaginaryPart * i where i2 = -1. Write a program to test your class.

Requirements:

• Use floating-point variables to represent the private data of the class.
• Provide a constructor that enables an object of this class to be initialized when it is declared.
• Provide a no-argument constructor with default values in case no initializers are provided.
• Provide public methods that perform the following operations:
a) Add two Complex numbers: The real parts are added together and the imaginary parts are added together.
b) Subtract two Complex numbers: The real part of the right operand is subtracted from the real part of the left operand, and the imaginary part of the right operand is subtracted from the imaginary part of the left operand.
c) Multiply two Complex numbers: Use the following formula,

Write a class Janitor to accompany the other employees. Janitors work twice as many hours (80 hours/week), they make $30,000 ($10,000 less than others), they get half as much vacation (only 5 days), and they have an additional method named clean that prints "Working' for the man."

a) Create a class named Rectangle with fields named length, width, area and perimeter.

b) Add a constructor that takes no argument and sets the length and width to 1.

Add methods named setLength(), getLength() that set and return the length respectively.
d) Add methods named setWith(), getWidth() that set and return the width respectively.

e) Add a method computePerimeter(), which computes a and returns rectangle's perimeter.

f) Add a method computeArea() which computes and returns a rectangle's area.

[Hint Area = Lengh x Width ; Perimeter = 2(Length + Width)]


g) Create a class named TestRectangle whose main() method declares two Rectangle objects.

h) Using the setLength() method, assign one Rectangle object a Length of 2.5cm and assign another a Length of 4.5cm.

i) Using the setWidth() method, assign one Rectangle object a width of 1.5cm and assign another a width of 2.5cm.

j) Call computePerimeter() and computeArea() for each rectangle and display the results.

I am trying to restrict character input in an option dialogue box.

ref:
http://www.roseindia.net/tutorial/java/swing/joptionpaneValidation.html

The code shown limits the string values that can be input.
(it can't keep you from entering a restricted value, it only alerts you to the entry.)
I am trying to get this code to work with a DOUBLE value.

So far I've been unsuccessful. Please help.

I haven't heard anything from you regarding my request. Should I assume that you are unable to find someone to help me with this assignment? If so, I need to know ASAP so that I can try another resource. My request is for Assignment #48152. Please advise. Thank you.
