I am trying to code a game following instructions contained in an OU TMA document which read:
In the constructor, write code to assign a new instance of Random to ran which you should create using the Random class's zero argument constructor
Will this code work?
Random ran = new Random(0) ;
I am a relative newbie to Java, and I don't understand exactly what the instructions mean

Is it possible to get Autocomplete or Something when i work with the eclipse form editor?
I write a color in the strings.xml and then i want to select it by the propertys for the text color, but there is no autocomplete or something equal
I found this piece of code:
char a = 1["ABC"];
A few quick test led me to the fact it was the same than writing:
char a = "ABC"[1];
Which seems far more logical to me. So my questions:
Why is this notation valid?
Is there any reason to write something that way?
I'm trying to write a regular expression which specifies that text should start with a letter, every character should be a letter, number or underscore, there should not be 2 underscores in a row and it should end with a letter or number. At the moment, the only thing I have is ^[a-zA-Z]\w[a-zA-Z1-9_] but this doesn't seem to work properly since it only ever matches 3 characters, and allows repeated underscores. I also don't know how to specify requirements for the last character.
I want to write the regex pattern which should match the string in between also.
For example:
I have writtenthe regex pattern like this
^((?!mystring).)*$
Which means match words which doesnot contain mystring. But i want regex pattern to match like this.
mystringabcdfrevrgf
regex matcher should return
abcdfrevrgf
How will i achieve this, Please help Thanks in advance.
Answer:
((?!mystring)(.*))$
I've been learning a little of C++ and Java but my main field of interest is gaming and i would like to write code for making my own 3D Games to complement my artistic expertise
I'm using a macro and I think it works fine -
#define CStrNullLastNL(str) {char* nl=strrchr(str,'\n'); if(nl){*nl=0;}}
So it works to zero out the last newline in a string, really its used to chop off the linebreak when it gets left on by fgets.
So, I'm wondering if I can "return" a value from the macro, so it can be called like
func( CStrNullLastNL( cstr ) ) ;
Or will I have to write a function
I have a table with my products and I'm trying to write a page that would pull bracelets with certain colors from the database. So here's what I have right now (in php):
$query = "SELECT * FROM products WHERE (products.colors LIKE '%black%')";
But I only want to select rows where the value for the column "category" equals "bracelet".
I've tried a few different things, but I keep getting warnings and errors. I appreciate any help you can give, thank you!
How would I write a SQLite query to select all records from a specific month?
My dates are stored as Unix timestamps. PHP code is allowed in your solution if it's required. SQLite2-compatible queries only, please. :)
Hi,
Does anyone know if it is possible to encode a video using ffmpeg in reverse? (So the resulting video plays in reverse?)
I think I can by generating images for each frame (so a folder of images labelled 1.jpg, 2.jpg etc), then write a script to change the image names, and then re-encode the ivdeo from these files.
Does anyone know of a quicker way?
This is an FLV video.
Thank you
I am hoping to write a script that will allow for the detection of video on a url and provide a download link to a *flv for google chrome.
Anyone have any suggestions were to start and get a footing?
I am able to create, write and read an SQLite Database in my Android App. I have a copy of the Database that is fully populated with data, and I want to get that data into the App's Database. Is it possible to access my pouplaed database from inside my App? Or can I at least create a copy of the populated database and then use that copy? Or do I need to do a .dump and put all the inserts into the Android code?

I have a table with three columns: patient_id, obs_date, and weight_val. patient_id stores patient identification #, weight_val stores a weight value, and obs_date stores the date when the weight reading was taken. So, a patient can have many different weight readings at different dates.
How do you write a query for:
select all patients whose last weight reading is 120?
I am trying to write a recursive method to print n number of asteriks in a line and create a new line at the end.
So, TriangleOps.line(5);
would print

if(n>0){
System.out.println("*");
line(n-1);
}}
instead it prints

*
*
*
*
with a lot of space at the end. Can anyone tell me how to remove the line breaks?
