In java Can objects be created with both static memory allocation and dynamic memory allocation?
Answer Snippets (Read the full thread at stackoverflow):
Variables, or in static code blocks , are statically allocated, in the sense that allocation is done.

I want to add a widget to the bottom of a scrolled window, then scroll to the bottom of that window. However, the window thinks it is already at the bottom, because the widget has still not been allocated. I.e., this returns -1:
widget.get_allocation(...

But see the note in the linked-to documentation, and investigate if those ways don't work better .
I'm not 100% sure I understand what you're trying to do, but still: At a minimum, you need to realize the widget to get it to compute those things .

I need to find out the "Allocation Unit Size" selected when a particular hard-disk was formatted.
It doesn't appear in the properties information for the drive.
Is there any easy way to get this information?

But this is far more quicker..
Thanks, I only knew the chkdsk command for this.
Use the fsutil command:
fsutil fsinfo ntfsinfo [drive letter]
You'll have to run this command with administrator privileges .

If you allocate some registers yourself.
Trust allocation unless you have very good reasons for it.
These days GCC can do a way better job than you can with register allocation.

I am getting a "bitmap size exceeds VM budget" error. I have read that there is a 16MB memory limit. In this thread Romain Guy says that "you can only allocate 16 MB of memory for your entire application".
However, my app must be running out of memory...

Have you tried profiling your memory usage with DDMS ... .
You could try using VMRuntime's setMinimumHeapSize, although as far as I know dalvik should automatically increase your Heap size when you run out of memmory (till it really runs out of memory :)) .

The default allocation unit size recommended when formatting a drive in our current set-up is 4096 bytes. I understand the basics of the pros and cons of larger and smaller sizes (performance boost vs. space preservation) but it seems the benefits of ...

I'm formatting a drive using NTFS which will be dedicated as a file share for users to centrally store their files. The files will likely be large (10's to 100's of megabytes).
Someone suggested that using a large allocation unit size than the default...

Good luck, any further ....
So you might want to keep that in mind if you plan not to plan for backups ;-)
A larger allocation then it might pay to increase the allocation size to 32KB or 64KB.

Strtok() basically modifies the input string.
You can write to the stack.
You cannot write to statically allocated string memory on most compilers/runtimes/hardware.
Strtok writes to the memory allocated to the string.

I have a program in which I want to be able to store certain data (dynamically allocated blocks), on disk for reduced memory usage and persistence.
My first thought was to write my own custom allocator which managed the content of files on the disk, but...
