Hi, I am a beginner in JAVA language...
I am making a simple sudoku game (in notepad -I have to use only notepad).
I have my sudoku tables stored in 2d arrays e.g sudoku1[9][9].
Lets say I have 5 2d-arrays, sudoku1....sudo ku5, and I want a random one to be chosen... how do I do that.
I know I have to use class Random, but how do I make it in this case (i.e 2d arrays)??
also
this is how u put values in a 2d array...
int [][] example2d=
{
{0, 3, 2},
{0, 5, 8},
};
how can u put values in a 3d array??
int [][][] example3d=
???????

But if I put them in a text file will I be able to retrieve a random table (pull randomly a whole 2d array).
I mean now that I have put them in a 3d one I can choose a random one. - my3DArray[ran.nextInt(3)][][]
Yes. At the start of your program, you can read in the sudoku puzzles into the 3d array, and can still use the above code to randomly select a puzzle.
how can the "user" store (meaning to store while the program is runned)?
How can that value stay permanently?
I'm not exactly sure what you mean by this...could you elaborate further as to what you're trying to accomplish?

Transferring arrays from C DLL's to VB.Net
I have a DLL written in C. This DLL reads a text file and creates a several

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
