// item in an Iterable of values Multimap<Character, String> multimap = Multimaps.index( words, new Function<String, Character>() { @Override public Character apply(String input) { return Character.toLowerCase(input.charAt(0)); } } ); multimap.get('a'); // -> [amet, adipisicing] mul...
In this article, we will learn about nested collections in Java and how we can transform them into flat collections using different approaches. 1. What is Flattening? In programming, flatting aListmeans merging several nested lists to create a single list. The flattened list consists of all the...
1. Converting Iterable to Stream TheIterables are useful but provide limited support for lambda expressions added in Java 8. To utilize full language features, it is desired to convert the iterable to stream. To convert, we will useiterable.spliterator()method to get theSpliteratorreference, whic...
Converting map object to NumPy arrayFor this purpose, we can use numpy.fromiter() where we can pass the map object. It is used to create a new 1-dimensional array from an iterable object. We can also define the data type of the elements of the numpy array which is going to be ...
Additionally,Mapobjects are also iterable from the get-go. Granted, you can iterate over an object’s properties using afor inloop, but that is not always an elegant solution. As such, here is how you can create and populate an associative array in JavaScript: ...

First, you create an empty set of window tabs that you’ll open in the future, passing it to the new window instance. Then, you run two Unix commands, pwd and ls, which get recorded in the window’s local history. When you pretty print the vars() of your window object, you get ...
to evaluate the entire method with references and the respective functions. In Java, there is no concept of standalone functions; therefore, what it does is defining and creating objects from these interfaces. The Iterable.filter() method can be used in cooperation with the objects of the ...
