I am having trouble interpreting/understanding the generic type of a Java List:How is the generic type ? extends Command called, like is there a name for it? What exactly is this type? Is it a Command object? Or does this mean that it only accepts classes extending Command? What is...
I want to delete everything in this column 3 characters after '18'I want my output to look likeI have tried the following code.
Let's say I have several vectorsand that I would like to see if the names of the first elements are equal.

Is it possible to use structured binding with vectors?E.g.Above code unfortunately doesn't work (under GCC), but maybe there's a different way (with structured binding) that allows to assign the first three values of a vector to three variables.
The question is this:Given a non-empty array of integers, every element appears twice except for one. Find that single one.
Are the rules/behaviors around @Autowired different when writing tests? It seems that with a test, you can autowire to a concrete type, but if you try the same thing inside a @Component it will fail. This is a contrived example, but it's something I ran into and am just trying...
In C++11, a constructor without explicit keyword can be used to convert a list of arguments implicitly to its class. For example:
Given a list in Python containing 8 x, y coordinate values (all positive) of 4 points as [x1, x2, x3, x4, y1, y2, y3, y4] ((xi, yi) are x and y coordinates of ith point ),
I saw this ReasonML vs TypeScript question here at StackOverflow, now I'm wondering how ReasonML and Elm compare to each other.
