This is a wireframe image of a 3d sphere that is used as input to the program.

Figure 2 - Possible output produced by the program in Listing 1 .

This is a possible output image from the program.

Answer 1

Question 2

True or False? The code in Listing 2 instantiates an object of an anonymous class.

Listing 2 . Question 2.
new Java3012raRunner().run();

Answer 2

Question 3

True or False? The code in Listing 2 instantiates an anonymous object..

Answer 3

Question 4

True or False? The statement shown in Listing 3 will return a reference to a Pixel object that represents a physical pixel located at a horizontal coordinate of col and a vertical coordinate of row .

Listing 3 . Question 4.
leftPixel = pix.getPixels(col,row);

Answer 4

What is the meaning of the following two images?

This image was inserted here simply to insert some space between the questions and the answers to keep them from being visible on the screen at thesame time.

The image is also an example of the kinds of things that we do in my course titled ITSE 2321, Object-Oriented Programming.

Spacer image of a rabbit and a penguin.

This image was also inserted for the purpose of inserting space between the questions and the answers.

Spacer image of a penguin in the snow in front of some houses.

Answers

Answer 4

False. The code in Listing 3 has the wrong spelling for the method that returns the Pixel object. The correct spelling is shown in Listing 4 . You learned about the spelling (with no parameters) shown in Listing 3 in an earlier module.

Listing 4 . Answer 4.
leftPixel = pix.getPixel(col,row);

Back to Question 4

Answer 3

True. The object instantiated from the class named Java3012raRunner is an anonymous object because its reference is not saved in a named referencevariable in the current scope. Anonymous classes and anonymous objects are entirely different topics.

Back to Question 3

Answer 2

False. A discussion of anonymous classes would be a somewhat advanced topic. That topic is not explained in the module named Java3012: Using Nested Loops to Process Pixels .

Back to Question 2

Answer 1

True.

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.
