Learn how to use for loops in Scala with examples and detailed explanations. Master looping constructs to enhance your Scala programming skills.
I just found some notes from when I first began working with Scala, and I was working with the yield keyword in for loops. If you haven't worked with something like yield before, it will help to know how it works. Also, when you need to do searches for problems, or when you want...
and the outerforloop continues. But if the secondifcondition is triggered, control of flow is sent toOuter.breakable, and both loops are exited. Running this object results in the following output:
Example, using yield with for loop that loops from 1 to 5, for (i <- 1 to 5) yield (i*5) Output scala.collection.immutable.IndexedSeq[Int] = Vector(5, 10, 15, 20, 25) for loop/yield examples Scala array Iterating elements of an array using for loop and then using the yield ...
In Scala, loops are not used as often as in other languages. You can often process the values in a sequence by applying a function to all of them, which can be done with a single method call.回到顶部 Advanced for Loops and for Comprehensions...
Loops while, do-while都和java的用法一样 for的变化很大,实际上for并不常用 for(i <- expr)// 意思是i将遍历右侧表达式中的每一个值 Advanced for Loops and for Comprehensions 一些基本的写法 for(i <-1to3; j <-1to3) print((10*i + j) +" ") ...
These directives are used for creating loops in Sass, enabling you to iterate over a range of values, a list, or a map and apply styles dynamically. 8. @media Allows you to write styles specific to different media queries, such as different screen sizes or device orientations. It helps ...
When programming in Java, controlling the flow of your code is crucial for efficiency and readability. One common scenario involves the use of loops, particularly the for loop. Sometimes, you may find yourself needing to exit a loop prematurely based on specific conditions. This is where the ...
In Scala we havefor-comprehensions as an imperative-looking syntax for writing monadic code, e.g. for{ x<-foo y<-bar(x) z<-baz }yield(y, z) Each monadic assignmenta <- maunwrapsa pure valuea: Afrom a monadic valuema: M[A]so that it can be used later in the computation. But...
"While" loops repeat a statement until the test becames falsy e.g.let i = 5 while (--i) { i }results in $ = [4, 3, 2, 1].For...of"For..of" loops iterate over array contents or record values e.g.for (const i of [1..5]) { 2 ^ (i % 5) }results in $ = [2^...
