DoubleStream skip() in Java
DoubleStream skip(long n) returns a stream consisting of the remaining elements of this stream after discarding the first n elements of the stream. If this stream contains fewer than n elements then an empty stream will be returned.
Note : DoubleStream skip() is a stateful intermediate operation i.e, it may incorporate state from previously seen elements when processing new elements. Stateful intermediate operations may need to process the entire input before producing a result. For example, one cannot produce any results from sorting a stream until one has seen all elements of the stream.
Syntax :
DoubleStream skip(long n)
Parameter :
- DoubleStream : A sequence of primitive double-valued elements. This is the double primitive specialization of Stream.
- n : The number of leading elements to skip.
Return Value : The function returns the new stream after discarding first n elements.
Exception : The function throws IllegalArgumentException if n is negative.
Example 1 :
// Java code for DoubleStream skip() function import java.util.*; import java.util.stream.DoubleStream; class GFG { // Driver code public static void main(String[] args) { // Creating a DoubleStream DoubleStream stream = DoubleStream.of( 5.5 , 2.6 , 4.6 , 7.0 , 13.2 , 15.4 ); // Using skip() to skip first 3 values in DoubleStream // and displaying the rest of elements stream.skip( 3 ).forEach(System.out::println); } } |
