In this tutorial, We'll take a look at anin-depth tutorial with examples on Java 8 Stream API. Java 8 introduced a new API which is called asStream. This API supports processing the large data sets in a sequential and parallel model. When we see the code that looks to the SQL query...
Java 8 streams API is a widely used feature to write code in a functional programming way. In this tutorial, we’ll discuss how to use Streams API for Map creation, iteration and sorting. Let’s create aUserclass and List of users, which we will use in the examples of this tutorial:-...

Since strings in Java are immutable, we need a helper class likeStringJoinerto let the collector construct our string. The supplier initially constructs such a StringJoiner with the appropriate delimiter. The accumulator is used to add each persons upper-cased name to the StringJoiner. The combiner ...
In this Java 8 stream tutorial, we learned tofinite stream elementsas well as infinite streams of elements. We saw the usage oflimit()function which is used to pick the first N elements from an infinite stream. Happy Learning !! Sourcecode on Github ...
Java Stream API provides excellent filtering capability on the elements in the Stream. Sometimes, the stream elements also contain the nested collections; we need to filter those elements in the nested collections. This Java tutorial discusses various approaches with examples to apply filtering on nest...
