public

问题 For some reason, I can't access any files in the public dir. Not found error. I'm not putting the public part in the URL, obviously. View the Lovers source code repository on GitHub. 回答1: Sweet. I fixed this.

问题 I'm currently programming a Blackjack application in Java and it needs to be written in an MVC architecture. I have all my models, views and controllers fully coded and everything works perfectly. However, I'm wondering what the best way of attaching listeners to components is (e.g, a JButton). My current design declares all components in the view that need listeners as public final. It then passes the view to the controller. From there, the controller has full reign to access the components

问题 I'm constructing a method to take in an ArrayList(presumably full of objects) and then list all the fields(and their values) for each object in the ArrayList. Currently my code is as follows: public static void ListArrayListMembers(ArrayList list) { foreach (Object obj in list) { Type type = obj.GetType(); string field = type.GetFields().ToString(); Console.WriteLine(field); } } Of course, I understand the immediate issue with this code: if it worked it'd only print one field per object in

问题 I have a quick issue. I am trying to use Laravel for the first time. To do so, I'm using Wamp. And I don't know if this is important, but I set the DocumentRoot of wamp at this address : DocumentRoot "C:\Users\Bebop\Documents\Site Internet/" I using wamp for a lot of different websites in a folder called Sites. When I access to one of the site I go to : localhost/Sites/thewebsite. So really what I want is just to get rid of the public folder in the path to the Laravel website. For the moment

问题 I was using these lines of code... public static final int WIDTH = 240; public static final int HEIGHT = 350; public static final int SCALE = 2; but I always got these errors ... Illegal modifier for parameter WIDTH; only final is permitted Illegal modifier for parameter HEIGHT; only final is permitted Illegal modifier for parameter SCALE; only final is permitted 回答1: I expect that you are trying to use public and static on local variable declarations or method parameter declarations. Locals

问题 I have a class like this : class Foo { public: Foo() { for(int i = 0; i < 10; ++i) v.push_back(i); }; const vector<double>& V() const {return v;}; protected: vector<double>& V() {return v;}; private: vector<double> v; }; And then a piece of code like this : Foo foo; for(int i = 0; i < (int) foo.V().size(); ++i) cout << foo.V().at(i) << endl; However, the latter raises a compilation error saying the V() call is a protected method while i am just trying to read from it, not modify it. I have

问题 Ruby as an Object Oriented Language. What that means is whatever message I send, I strictly send it on some object/instance of class. Example: class Test def test1 puts "I am in test1. A public method" self.test2 end def test2 puts "I am in test2. A public Method" end end makes sense I call method test2 on self object But I cannot do this class Test def test1 puts "I am in test1. A public method" self.test2 # Don't work test2 # works. (where is the object that I am calling this method on?)

问题 I happen to come across a Java code at my work place. Here's the scenario: There are 2 classes - ClassA and ClassB . ClassA has nothing except 4 public static final string values inside it. Its purpose is to use those values like ClassA.variable (don't ask me why, it's not my code). ClassB imports ClassA . I edited the string values in ClassA and compiled it. When I ran ClassB I could see it was using the old values - not the new values. I had to recompile ClassB to make it use new values
