Specifications

Build a simple class using the following specifications

ArithmeticManager class

Variables: operand1, operand 2 (double)

Methods: Value return methods that will add, subtract, multiply, and divide the two operands

Set/get methods for both variables

A parameterized constructor to set the initial operand values as object is constructed

Access the provided graphical user interface at:

http://websites.delta.edu/teklingl/cs1/inpgm2/

however this is incomplete. Once you complete your class, integrate on object of your class into a project that will create a simple application to perform basic arithmetic on two numbers. Your program should include the following behaviors:

As it is launched, initialize your object with the provided basic dialog box prompts

When the user pressed any button, get the values in the respective text fields, set the data in your object, perform the operation, and finally set the result from the method call the answer text field.
