Discussion

The following is a non-exhaustive list of concepts that you need to understand along with knowledge and skills that you need to possess in order tosuccessfully write this programand/or understand the given solution in Prob03.java . Some of these items are general in nature and some are specific to the use of Ericson's multimedia library. I won't repeat the items listed above.Instead, I will concentrate on new concepts, knowledge, and skills not included in the above lists.

There are at least two alternative ways to write a program that will satisfy these requirements.

Both alternatives

  • How to design and implement an algorithm that will transform Prob03.jpg into the required output imageshown in Figure 3 .

Alternative 1

Alternative 2

Listing 3 - Write the Java application described below.

/*File Prob03 Copyright 2012 R.G.Baldwin

Write a program named Prob03 that uses the class definition shown below and Ericson's media libraryalong with the image file named Prob03.jpg to produce the graphic output image shownin Figure 3 below.

Click Prob03.java to download a Java source file containing the solution to this program.

In addition to the output, your program must display your name and the other text shownbelow on the command-line screen:

Display your name here. Picture, filename Prob03.jpg height 274 width 365*********************************************************/ public class Prob03{//DO NOT MODIFY THE CODE IN THIS CLASS DEFINITION. public static void main(String[]args){ Prob03Runner obj = new Prob03Runner();obj.run(); System.out.println(obj.getPicture());}//end main }//end class Prob03//End program specifications.

Program 4

Discussion

The following is a non-exhaustive list of concepts that you need to understand along with knowledge and skills that you need to possess in order tosuccessfully write this programand/or understand the given solution in Prob04.java . Some of these items are general in nature and some are specific to the use of Ericson's multimedia library. I won't repeat the items listed above.Instead, I will concentrate on new concepts, knowledge, and skills not included in the above lists.

  • How to design and implement an algorithm that will transform Prob04.jpg into the image shown in Figure 4 .
  • Similarities and differences between classes and interfaces .
  • The different types under which you can store an object's reference whenthe class from which the object was instantiated extends a class and implements one or more interfaces.
  • The kinds of new relationships that are created when a class implements one or more interfaces.
  • The implications of inheriting one or more abstract methods.
  • The significance of all interface methods being implicitly abstract.
  • That DigitalPicture is an interface and is not a class in Ericson's library.
  • The relationship that exists between the DigitalPicture interface and the Picture class.
  • The circumstances under which an accessor method can return a reference to an object as type DigitalPicture .
  • The difference between displaying a Picture object with the show and explore methods.

firm is the unit which transform inputs to output where as industry contain combination of firms with similar production 😅😅

Suppose the demand function that a firm faces shifted from Qd  120 3P to Qd  90  3P and the supply function has shifted from QS  20  2P to QS 10  2P . a) Find the effect of this change on price and quantity. b) Which of the changes in demand and supply is higher?
