instantiation

How can I create/instantiate an array to be equal to the substring of another array, where the size of the substring is unknown: int n; //some number derived somewhere else String[] grp = elements[i] to elements[i+n]; Use Arrays.copyOfRange : public static <T> T[] copyOfRange(T[] original, int from, int to) Copies the specified range of the specified array into a new array. The initial index of the range ( from ) must lie between zero and original.length , inclusive. The value at original[from] is placed into the initial element of the copy (unless from == original.length or from == to ).

Probably my question is a trivial one, but I never used an application scope bean before. I need the application bean because I have to do time consuming transactions on the database. my search didn't satisfy my curiosity at all. I don't know why but I didn't manage to initialize the bean (it is null) or it the app crashed. So I have an application scope bean @ManagedBean(eager=true) @ApplicationScoped public class ApplicationContainer { ... } eager=true I read that tells JSF to initiate the bean every time when the application server (I use GlassFish) is started. I read in several places that

I am trying to get my hands dirty learning DDD (by developing a sample eCommerce site with entities like Order , OrderLines , Product , Categories etc). From what I could perceive about Aggregate Root concept I thought Order class should be an aggregate root for OrderLine . Things went fine so far, however I am confused when it define a create order flow from UI. When I want to add an order line to my order object, how should I get/create an instance of an OrderLine object: Should I hardcode the new OrderLine() statement in my UI/Service class Should I define a method with parameters like

A picture is worth a thousand words, how to rewrite this code from Objective-C to Swift? - (id) instanceOfClass: (Class) class withInitializer: (SEL) initializerSelector withObject: (id) object { id obj = nil; if([class instancesRespondToSelector:initializerSelector]) { obj = [[class alloc] performSelector:initializerSelector withObject:object]; } return obj; } id myViewController = [self instanceOfClass:[ViewController class] withInitializer:@selector(initWithObject:) withObject:@"super-string!"]; NSLog(@"%@", myViewController); This cannot be done purely in Swift. You can only do this by

I am in a situations where i need to instantiate a class with arguments from within an instance of another class. Here is the prototype: //test.php class test { function __construct($a, $b, $c) { echo $a . '<br />'; echo $b . '<br />'; echo $c . '<br />'; } } Now, i need to instantiate above class using below class's cls function: class myclass { function cls($file_name, $args = array()) { include $file_name . ".php"; if (isset($args)) { // this is where the problem might be, i need to pass as many arguments as test class has. $class_instance = new $file_name($args); } else { $class_instance =

Is it possible to instantiate a module conditionally in verliog ? example : if (en==1) then module1 instantiation else module2 instantiation From IEEE Std 1364-2001 : 12.1.3.3 generate-conditional A generate-conditional is an if-else-if generate construct that permits modules, user defined primitives, Verilog gate primitives, continuous assignments, initial blocks and always blocks to be conditionally instantiated into another module based on an expression that is deterministic at the time the design is elaborated. example given in LRM : module multiplier(a,b,product); parameter a_width = 8, b
