So, we'll now give a brief overview of the improvements that Java 9 brought to the Streams API. Let's do it. takeWhile. The takeWhile method is one of the new additions to theWhat is the difference between where and TakeWhile method in Linq? Different Types of examples using the TakeWhile Operator in Linq. What are the need and use of the TakeWhile Method in C#.NET? The TakeWhile Method in Linq is used to fetch all the elements from a data source or sequence until a specified condition is true. It's used to print the first element (the head element) of a list: scala> nums.head res0: Int = 1 scala> names.head res1: String = joel. Because a String is a sequence of characters, you can also treat it like a list. This is how head works on these strings: scala> "foo".head res2: Char = f scala> "bar".head res3: Char = b.Underscore In Java. Underscore (_) is a symbol that is used to combine multi-words in a single identifier sometimes refers to a variable in a programming context.
