Not quite clear on your code, but when you remove an element from an ArrayList that you are iterating through, you do not want to increment the index, otherwise you will skip elements, e.g.: ArrayList<…> list = …; for (int i = 0; i < list.size(); ) { if (shouldBeRemoved) list.remove(i); else ++ i; } … Read more
Really, you are asking two different questions. Entity Framework is not a database administration tool and as such does not have any functionality for directly loading data from a spreadsheet. If you research each part of your question separately, you might have more luck. Seeding data with Entity Framework Reading Excel Files with C# Reply … Read more

for j in xrange(10,40,5): What this loop will generate? 10,15,20,25,30,35 Notice, it will generate 10 but not 40 as the first param is inclusive, but second one is exclusive. Then which of them is not divisible by 3? 10,20,25,35 Simple as that. For your added question, see this: for char in “ABC 123”: print char, … Read more

Rust’s standard library is kept small intentionally to minimise binary size ease maintenance (among other reasons). Because Rust is not Python, and there’s no reason for it to … Read more

First, let’s define what we need. We need a table (view) with these fields: ProductId, ProductName, ProductViewCount, and RootCategoryId. Imagine, the Category table has RootCategoryId field already. Then we can use this query to receive the result: SELECT P.Id AS ‘ProductId’, P.Name AS ‘ProductName’, PVC.ProductViewCount, C.RootCategoryId FROM Category C INNER JOIN ProductCategory PC ON PC.CategoryId … Read more
super() calls the parent constructor of the class and this() calls the constructor defined within the class. //Example of super() class parent { parent() { } } class child() { child() { super(); //Go to parent class constructor } } //Example of this class test { test() { this(“a”); //go to test one argument constructor … Read more
