Java 8 Stream flatMapToInt, flatMapToLong and flatMapToDouble Example
By Arvind Rai, June 04, 2016
On this page we will provide Java 8 Stream flatMapToInt, flatMapToLong and flatMapToDouble example. flatMapToInt is used for int data type, flatMapToLong for long data type and flatMapToDouble for double data type. They behave same as flatMap but for primitive data types.
flatMapToInt
It is used for primitive int data type. It returns IntStream.
According to java doc.
"Returns an IntStream consisting of the results of replacing each element of this stream with the contents of a mapped stream produced by applying the provided mapping function to each element."
Now find the example.
