Kirat[ad_1] Suppose the original code had been int count; count = 1; This does two things. The first line creates a variable called count, of type int. The second line assigns a value to that variable. Because it’s very common to assign a value to a variable as soon as it’s created, Java lets you … Read more

[ad_1] A quick test case shows that Chrome, at least, fetches all the stylesheets no matter what the media query says. This isn’t really surprising as users can resize windows. It holds true for device-width as well though. So there are no savings at all since all the stylesheets are downloaded. This comes with the … Read more
[ad_1] To restart from scratch : What I understand your question should have been : I have a sequence of Strings and want to check the difference between them. Whenever a line is the same as the previous one, i want to increment a counter (that counted the occurence of that line). Whenever a new … Read more
[ad_1] The test (result != X_WON || result != O_WON || result != DRAW) is always true, since result can’t be equal to all 3 values. result should be initialised to UNFINISHED and the test changed to: (taken != 9 && result == UNFINISHED) 0 [ad_2] solved game does not allow you to win
[ad_1] You have a couple of problems with your code. First, you should stop the loop before i has the value list.size(). (Actually, since the index of the element is not used, you can use an enhanced for loop, which is what I show below.) Second, you need to test for the condition you want, … Read more
[ad_1] Before mapToDouble you have to use flatMap like this: return collection1.stream() .flatMap(cA -> cA.getCollectionB().stream()) .mapToDouble(ObjectB::getSalary) .sum(); Or you can use map before the flatMap: return collection1.stream() .map(ObjectA::getCollectionB) .flatMap(List::stream) .mapToDouble(ObjectB::getSalary) .sum(); Of you can use flatMapToDouble directly as @Naman mentioned: return collection1.stream() .flatMapToDouble( cA -> cA.getCollectionB().stream().mapToDouble(ObjectB::getSalary) ).sum(); 5 [ad_2] solved Calculate the sum of a … Read more
[ad_1] The problem here is that you are referencing two completely different objects. In viewDidLoad you create ThongTinBNPage2 viewController and then add it to the viewControllers property of the pageViewController. However, the objects stored in VCArr are two totally different viewControllers. Let’s think about it this way: When viewDidLoad is called you create viewController object … Read more
[ad_1] Your problem is that while the generic parameter of TreeNode is Comparable, the class itself is not. Change this: public static class TreeNode<E extends Comparable<E>> { To this: public static class TreeNode<E extends Comparable<E>> implements Comparable<TreeNode<E>> { Or if you don’t require the generic type to also be Comparable: public static class TreeNode<E> implements … Read more
[ad_1] It appears that variable is an array that stores references (URIs, or paths) to images, that is fed to the src attribute of an image element, <img>. The script simple does the following logic: When the function is fired, it increments index by 1 If index is equal to the number of images, you … Read more

[ad_1] I’m not sure if I understand the question properly, but here’s how you can declare an argument that is a function taking two arguments – any and string – and returning void (that’s what I think the type of the function should be when I look at your code): return function (boundTransportFn: (a: any, … Read more
[ad_1] Dictionarys are mappings from a key to a value. ContainsKey() checks if your dictionary contains a certain key, it is very fast – looking up keys (and finding the data associated with that key) is the main strength of dictionaries. You might need this, to avoid accessing a non-existent Key – read about TryGetValue() … Read more
