IntStream limit(long maxSize) returns a stream consisting of the elements of this stream, truncated to be no longer than maxSize in length.
Note : IntStream 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 :
IntStream limit(long maxSize)
Parameters :
- IntStream : A sequence of primitive int-valued elements. This is the int 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 IntStream limit // (long maxSize) import java.util.*;
import java.util.stream.IntStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an IntStream
IntStream stream = IntStream.of( 2 , 4 , 6 , 8 , 10 );
// Using IntStream 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 4 6
Example 2 :
// Java code for IntStream limit // (long maxSize) import java.util.*;
import java.util.stream.IntStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an IntStream of numbers [5, 6, .. 11]
IntStream stream = IntStream.range( 5 , 12 );
// Using IntStream 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 :
5 6 7 8
Example 3 :
// Java code for IntStream limit // (long maxSize) import java.util.*;
import java.util.stream.IntStream;
class GFG {
// Driver code
public static void main(String[] args)
{
// Creating an IntStream
IntStream stream = IntStream.iterate( 4 , num -> num + 2 );
// Using IntStream 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 6 8 10
Difference between IntStream limit() and IntStream 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.
