Dress hats, casual caps - are even perfect for a beach day. The beauty of a Scala hat or cap is that it can be worn for any occasion. Since 1988, combined style with function, to keep wearers’ fashion identities well ahead of the coming trends. For women, it helps every wearer exude beauty and showcase her unique fashion sense with aplomb. For men, it invokes the long-forgotten hap tip, the holding car doors open and the extended forearm for a companion stepping out of a car. This brand has established itself as a trendsetting sartorial maven. Scalia hats may even be so delicately created as to be considered an inspiration. This collection of hat styles, thoughtful craftsmanship and machine-like consistency is evident in each and every item. Here we discuss a brief overview of Scala flatMap and its Benefits along with different examples and code Implementation.These hats are made with carefully selected straws and materials in a distinctive style. Also, we can give our own implementation if we want. It also helps in faster processing of collection elements by making them parallel. Var result = source.flatMap(_.toUpperCase)įlatMap in Scala are used to generate a separate set of sequence it is used with collection data structures and we can also use them with mutable and immutable collection objects. applying flatmap to modify list elemnts Val source = Seq("hnjik", "school" ,"new string", "old string", "learn") In this example, we are trying to convert the list of elements into uppercase by calling a function inside flatMap. Println("list after flatmap call ::" + list1) Var list1 = source.flatMap(_.toLowerCase) Println("list beforflatmap call ::" + source) This example use flatMap() method to separate the input given. Println("Here is the list2 with after flatten() " + list2) Println("Here is the list1 with map() and befor flatten() " + list1) Val source = Seq("Bhaaa", "Amit", "Shah", "OPPOPOPOP", "ASHERERERE") This example will show how it works internally and how two methods can be replaced and code can be optimized for doing the same thing. The example to show the map and flatten to demonstrate the same output by using two methods. Examples to Implement Scala flatMapīelow are the examples of Scala flatMap: Example #1 flatten methods: By this, we can reduce or optimize our lines of code and make it efficient. We can easily make our newly created collection parallel by using Parallel collection, then by simply calling the function n newly created parallel collection will process the elements parallel It will also speed up the processing of elements.Ĭombine two methods as one: Here flatMap combines two methods functionality which as map and Examples.Ģ. Parallel processing: We can also achieve parallel processing by using a flat map in Scala. But here the elements of the list will be modified and will be a separate sequence of string rather than a group.Ĭlass definition of FlatMap as per Scala Documentation: classFlatMap extends AbstractViewĪbstractView =>FlatMap =>IterableOnceExtensionMethod Benefits of Scala flatMapġ. Println(collection.flatMap(x => x + "hello"))Įxplanation: In the above example, we are using flat Map method to understand the functionality in details, First we are creating a collection which contains a list of string objects and then immediately after creation we are calling flat Map method on that particular collection and this flat Map method will give us newly created list. We can one example to understand how it works: It does all the three steps mentioned above. So this above case you can go for flatmap method of scala.
