Silly java test question

if you had to answer:

Java is different from other languages like C and C++ because it does not create machine and operating system specific code. Instead it creates _____________ that can be run on many platforms

what would you say ?

I would say "go read some books instead of asking others to answer your homework for you"

Go and read up on what the Java Virtual Machine is. This will help you understand why a program compiled in C++ to a windows executable won't run on Linux but Java code compiled to a jar (not the answer btw) file probably will. University is about learning yourself, you won't get very far if you can't do this because it is a key part of university. The biggest shock when you start Uni is that the learning technique is nothing like school or even collage.

You really should be able to answer that yourself; if you can't, then it certainly won't be difficult to find the answer.

well iv said its java bytecode, wrong answer apparently :s, hence why im asking on here, it also asked:

A one line comment in Java is signified by the characters ____

im 99.999999999% certain the answer is : //

if not that, /*, both incorrect answers apparently ?? im sure its // for the above question

Have you ever written any Java?

Dj_Jestar · 26 Oct 2007 at 12:02

"I'm feeling lucky!" on Google for criteria "java comment" produced: http://java.sun.com/docs/codeconv/html/CodeConventions.doc4.html

done the basics yeah, comments in code iv done are //, and it works, compiles etc, so im not getting why // is the wrong answer, iv written it 'slash slash' the problem is its a 'online test' not a human marker so iv got to put the answer in that the pc database has, is //, slash slash, what ever the answer to 'A one line comment in Java is signified by the characters ____ ' though ? just yes or no would be great as then I know that the database is going wrong or not, as im very sure its //, if its not just say 'no' then ill go off and find the right answer, if it is, just say 'yes' so I dont pull my hair out,lol

edit: iv also written in /* and 'slash star' also wrong answers !! I know a ruddy comment is // or /* , specifically // is a one line comment /* is a 'traditional' comment that needs to be ended */

Am I right or wrong here? yes or no ! lol

If you ask me the online test database is erroring, im so certain im right on this question

EDIT: RIIIGGHTT ok fine the lec just emailed me saying the database is wrong, haha i was right then !

Languages that are run on a runtime engine like .net and java are compiled to an intermediate language, of which bytecode is an example.

// are single line comments in java, was this marked by a lecturer or was it automatically marked online or something?

Yup turns out for the 8 questions i tried i got ALL of them right, the database said I was wrong on all, hence me throwing a wobbly and shouting i KNOW im right !! grrrr

lol

Doesn't look good for the lecturer if his database is wrong

Maybe he needs to go back to uni and do a few more lessons.
