DoubleStream limit(long maxSize) returns a stream consisting of the elements of this stream, truncated to be no longer than maxSize in length.
Note : DoubleStream limit() is a short-circuiting stateful intermediate operation i.e, when processed with an infinite input, it may produce a finite stream as a result without processing the entire input.
Syntax :
DoubleStream limit(long maxSize)
Parameters :
- DoubleStream : A sequence of primitive double-valued elements. This is the double primitive specialization of Stream.
- maxSize : The number of elements the stream should be limited to.
Return Value : The function returns a stream consisting of the elements of this stream, truncated to be no longer than maxSize in length.
Exception : The function throws IllegalArgumentException if maxSize is negative.
Example 1 :
// Java code for DoubleStream limit// (long maxSize)import java.util.*;import java.util.stream.DoubleStream;  class GFG {      // Driver code    public static void main(String[] args)    {        // Creating an DoubleStream        DoubleStream stream = DoubleStream.of(2.3, 4.4, 6.7, 8.9, 10.5);          // Using DoubleStream limit(long maxSize) to        // get a stream consisting of the elements of        // this stream, truncated to be no longer        // than maxSize in length.        stream.limit(3).forEach(System.out::println);    }} |
Output :
2.3 4.4 6.7
Example 2 :
// Java code for DoubleStream limit// (long maxSize)import java.util.*;import java.util.stream.DoubleStream;  class GFG {      // Driver code    public static void main(String[] args)    {        // Creating an DoubleStream        DoubleStream stream = DoubleStream.iterate(4.5, num -> num + 3);          // Using DoubleStream limit(long maxSize) to        // get a stream consisting of the elements of        // this stream, truncated to be no longer        // than maxSize in length.        stream.limit(4).forEach(System.out::println);    }} |
Output :
4.5 7.5 10.5 13.5
Difference between DoubleStream limit() and DoubleStream skip() :
- The limit() method returns a reduced stream of first maxSize elements but skip() method returns a stream of remaining elements after skipping first maxSize elements.
- limit() is a short-circuiting stateful intermediate operation i.e, when processed with an infinite input, it may produce a finite stream as a result without processing the entire input but skip() is a stateful intermediate operation i.e, it may need to process the entire input before producing a result.
