Preface

This module contains review questions and answers keyed to the module titled Jb0140: Java OOP: Java comments .

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? Comments in your source code are ignored by the compiler.

Answer 1

Question 2

True or false? Java supports the four styles of comments.

Answer 2

Question 3

True or false? The javadoc tool is a special program that is used to compile Java programs.

Answer 3

Question 4

True or false? Comments recognized by the javadoc tool begin with /** and end with */

Answer 4

Question 5

True or false? Multi-line comments begin with /# and end with #/

Answer 5

Question 6

True or false? The multi-line comment style is particularly useful for creating large blocks of information that should be ignored by the compiler.

Answer 6

Question 7

True or false? The multi-line comment style cannot be used to produce a comment consisting of a single line of text.

Answer 7

Question 8

True or false? Single-line comments begin with // and end at the end of the line.

Answer 8

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 coursetitled ITSE 2321, Object-Oriented Programming.

Abhijith Reply
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.

what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google

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
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
