Question

in visual c#

must include public delegate void MyCallback (object obj)

If given the following delegate declaration:
public delegate void MyCallback(object obj);
write code segments to perform the following:
A)
, Design a non-static method that can be contained within an instance/object
of the MyCallback delegate type. This method should display values of two data
fields contained within the object that is passed to the method. Make-up your own
method definition that meets these requirements.
B) (^ c) Creat an instance of the MyCallback delegate (i.e. a delegate object) and
initialize this object to contain an entry point of the method defined in part A) as well as
a copy of the object that calls this method. Include the declaration statement of the
object needed to create the required delegate instance.
C) (
;) Writ a statement that uses the delegate object created in part B) to call the
method contained within this delegate object and include error checking.

A).
Use the MyCallback delegate type from question 2) to creat an
event field and the corresponding event property. Make up your own event identifiers.
B) (
) Writ a complete statement that will add the method that you created
in question 3 A) to be a handler of the event you created in this question. Make up
your own object name that raises the event.

Problem Description and Given Info For this assignment you are given the following Java source code files: IStack.java (This file is complete – make no changes to this file) MyStack.java (You must complete this file) Main.java (You may use this file to write code to test your MyStack) You must complete the public class named MyStack.java with fields and methods as defined below. Your MyStack.java will implement the IStack interface that is provided in the IStack.java file. You must implement your MyStack class as either a linked list or an array list (refer to your MyArrayList and MyLinkedList work). Your MyStack must not be arbitrarily limited to any fixed size at run-time. UML UML CLass Diagram: MyStack Structure of the Fields While there are no required fields for your MyStack class, you will need to decide what fields to implement.

Portfolio Instructions: You are working for a financial advisor who creates portfolios of financial securities for his clients. A portfolio is a conglomeration of various financial assets, such as stocks and bonds, that together create a balanced collection of investments. When the financial advisor makes a purchase of securities on behalf of a client, a single transaction can include multiple shares of stock or multiple bonds. It is your job to create an object-oriented application that will allow the financial advisor to maintain the portfolios for his/her clients. You will need to create several classes to maintain this information: Security, Stock, Bond, Portfolio, and Date. The characteristics of stocks and bonds in a portfolio are shown below: Stocks: Bonds: Purchase date (Date) Purchase date (Date) Purchase price (double)…
