Hello.
Can anyone please suggest some good tutorial links where Java Vectors
and Arrays are explained and compared?
I'm a proficient programmer but fairly new to Java. Whilst I understand
arrays I don't fully understand Vectors and when to use them.
Many thanks.

Some other posters have already given you links, but a one sentence
summary might be that arrays are fixed-length, while Vectors are
variable-lengthed. I'm assuming, by the way, that when you say "Arrays", you
actually mean "arrays", and not, for example, "ArrayList" (the latter also
being variable-length).

I have made a small program that plots the orbit of a planet in visual
python using visual.vector for all values. If i run the program it is
clear that the orbit is non-keplerian as the planets gradually moves
away from the sun. I am pretty sure the orbit should be keplerian so i
guess there must be some source of error in the program.

I need to represent 1D and 2D arrays of numeric or bool types in a C++
program. The sizes of the arrays in my intended application are
dynamic in the sense that they are not known at compile time, so I'd
like to use an STL container class template such as valarray or vector
to represent 1D arrays, and valarrays or vectors of valarrays or
vectors to represent 2D arrays.
As I said the sizes of the arrays in my intended application are...

Hello all,

Also, I'd appreciate any comments anyone has on the suitability of the

I have a class that contains an array of integers that hold the state
of my 'system'. The system must be updated periodically. I need to
update the whole system at once, at which point the system is in a new
state. The update process depends upon the entire system state prior
to updating...that is, a single array cannot be serially updated, with
the results stored back into itself.
Just to give an indication of what I'm doing, the...

I was reading through Accelerated C++ at work when I read through the first
mention of Vectors, giving us certain functions etc.
Is there any benefit of Arrays over Vectors? Since all Vectors seem to be
(in my eyes at least) are glorified Arrays.
- Now I know there's a bit more difference, but what exactly are the
advantages of Arrays over Vectors (if any)?
Oh, and please keep it in mind I am a real beginner in C++ but can

Hello.
I am having some problem organizing a set of vectors. The vectors itself,
could contain a pointer( say integer pointer) or could contain another
object MyClass.

types into a single set. Something like a set<vector<void*>, my_compare func

Right now, I am having them as two different set dayatypes.

The attached program is fine, but I need to create vectors for each
AcctExample object. I know that I can do the following:
vector<AcctExample> example which makes a vector of AcctExample objects
called example. Now, how do I activate the methods for each object?
Also, why are we replacing templates with vectors? (That was what the
assignment required. I don't get why we do this).

Hi Guys,
In C++ , i was just wondering what is the advantage of Vectors over arrays?
I saw one sample program doing pretty much same way traditional vectors do then what the use of VECTORS??or what is their advantage??

How would I do this?
I want to be able to handle vectors of many different types of data
and vectors that can contain any number of other vectors of data.
Currently, I have a templated function that handles vectors of vectors
of <typename T(which could be anything from int to vectors of
something else). As well, I have specialized/overloaded functions to
handle the single-level vectors of data (e.g. vector<string>). So the

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
