I'm learning about lambda expressions. Given a list of names, I want to count the numbers of names that start with N.
A super simple question:Here's my plain Java code using traditional ternary operator ?My best bet is following:
I want to have a struct that takes an arbitrary number of lambdas and serve as a central calling point for all their call operators.
So, this doesn't work, since seatsAvailable is final. How can what I'm trying to accomplish be done using more of a lambda-style-from-the-ground-up way?
I know this could seem very stupid for non-noob C++ developers, but what are the differences between these 4 lambda expressions? Code:
Suppose you have a function that takes a std::vector of any type and processes it in some way:Since C++14, we are able to achieve the same thing with lambdas. In this case, we call them generic lambdas, since we introduce a template-like deduction to them:
I am trying to find the best average score from below two dimensional array:The output is: 80 (Arthit's score (60+100)/2)
I am trying to use Java's LambdaMetaFactory to dynamically implement a generic lambda, Handler<RoutingContext>:
I noticed that I get the same effect if I define this trivial function:and if I define a variable and assign a lambda (with an identical body) to it:
I am comparing 2 maps using Java 8 features and based on condition wants to return the result. Using .forEach is showing compile time error and basically, the return is returning from Lambda expression and not from the loop. How can I return from the loop enclosing the lambda? Note...
