IntStream count() in Java with examples

IntStream count() returns the count of elements in the stream. IntStream count() is present in java.util.stream.IntStream
Syntax :

long count()

Example 1 : Count the elements in IntStream.

// Java code for IntStream count() 
// to count the number of elements in 
// given stream 
import java.util.*; 
import java.util.stream.IntStream; 
  
class GFG { 
  
    // Driver code 
    public static void main(String[] args) 
    { 
  
        // creating a stream 
        IntStream stream = IntStream.of(2, 3, 4, 5, 6, 7, 8); 
  
        // storing the count of elements 
        // in a variable named total 
        long total = stream.count(); 
  
        // displaying the total number of elements 
        System.out.println(total); 
    } 
} 

Output :

Example 2 : Count the elements in a given range.

// Java code for IntStream count() 
// to count the number of elements in 
// given range excluding the last element 
import java.util.*; 
import java.util.stream.IntStream; 
  
class GFG { 
  
    // Driver code 
    public static void main(String[] args) 
    { 
  
        // creating a stream 
        IntStream stream = IntStream.range(2, 50); 
  
        // storing the count of elements 
        // in a variable named total 
        long total = stream.count(); 
  
        // displaying the total number of elements 
        System.out.println(total); 
    } 
} 

Output :

Example 3 : Count distinct elements in IntStream.

// Java code for IntStream count() 
// to count the number of distinct 
// elements in given stream 
import java.util.*; 
import java.util.stream.IntStream; 
  
class GFG { 
  
    // Driver code 
    public static void main(String[] args) 
    { 
  
        // creating a stream 
        IntStream stream = IntStream.of(2, 3, 4, 4, 7, 7, 8); 
  
        // storing the count of distinct elements 
        // in a variable named total 
        long total = stream.distinct().count(); 
  
        // displaying the total number of elements 
        System.out.println(total); 
    } 
}
