StreamDemo.java
import java.util.ArrayList;
import java.util.List;

public class StreamDemo
{
public static void main(String[] args)
{
List<Product> productList = new ArrayList<Product>();

// Adding Products
productList.add(new Product(1, "Sony mobile", 25000));
productList.add(new Product(2, "Lenovo mobile", 15000));
productList.add(new Product(3, "Nokia mobile", 10000));
productList.add(new Product(4, "Samsung mobile", 40000));

long countOfProducts = productList.stream()
.filter(p -> p.getPrice() < 20000)// Filter the product, whose price is less than 20000
.count(); // Returns the count of elements in this stream.

System.out.println("CountOfProducts = " + countOfProducts);
}

}
Output
CountOfProducts = 2
