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.

are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
