Preface

This module contains review questions and answers keyed to the module titled Jb0120: Java OOP: A Gentle Introduction to Java Programming .

The questions and the answers are connected by hyperlinks to make it easy for you to navigate from the question to the answer and back again.

Questions

Question 1 .

True or false? All data is stored in a computer in numeric form. Computer programs do what they do by executing a series of calculations on numeric data.It is the order and the pattern of those calculations that distinguishes one computer program from another.

Answer 1

Question 2

True or false? When we program using Java, we must perform most of the detailed work.

Answer 2

Question 3

True or false? As the computer program performs its calculations in the correct order, it is often necessary for it to store intermediate resultssomeplace, and then come back and get them to use them in subsequent calculations later.

Answer 3

Question 4

True or false? The structured solution to a computer programming problem is often called an algorithm.

Answer 4

Question 5

Which, if any of the following activities is not commonly believed to be fundamental activities of any computer program:

  • A. sequence
  • B. selection
  • C. loop

Answer 5

Question 6

True or false? As a programmer using a high-level language such as Java, you usually don't have to be concerned about the numeric memory addresses ofvariables.

Answer 6

Question 7

Why is modern computer memory often referred to as RAM?

Answer 7

Question 8

True or false? The process of declaring a variable

  • causes memory to be set aside to contain a value, and
  • causes that chunk of memory to be given an address.

Answer 8

Question 9

True or false? A value of the type int must be an integer.

Answer 9

Question 10

True or false? In programmer jargon, storing a value in a variable is also referred to as assigning a value to a variable.

Answer 10

Question 11

True or false? A reference to a variable name in Java code returns the value stored in the variable.

Answer 11

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.

Answers

Answer 11

True.

Back to Question 11

Answer 10

True.

Back to Question 10

Answer 9

True.

Back to Question 9

Answer 8

False. The process of declaring a variable

  • causes memory to be set aside to contain a value, and
  • causes that chunk of memory to be given a name .

Back to Question 8

Answer 7

Modern computer memory is often called RAM or random access memory because it can be accessed in any order.

Back to Question 7

Answer 6

True. You are able to think about variables and refer to them in terms of their names. (Names are easier to remember than numeric addresses). However, deep inside the computer, these names are cross-referenced to addresses and atthe lowest level, the program works with memory addresses instead of names.

Back to Question 6

Answer 5

None. All three are commonly believed to be the fundamental activities of any computer program.

Back to Question 5

Answer 4

True.

Back to Question 4

Answer 3

True.

Back to Question 3

Answer 2

False. Fortunately, when we program using a high-level programming language such as Java, much of the detailed work is done for us behind the scenes.

Back to Question 2

Answer 1

True.

is Bucky paper clear?
CYNTHIA
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.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
