        List<Integer> l = Array.list( 5, 10, 12, 30, 8, 7 );

        l.stream()

        .filter( x -> x % 2 == 0 )

        .filter( x > 10 )

        .forEach( System.out::println ); 

    }

}

Do streams have their own storage?

                                .sum();

        System.out.println(sum);

    }

}

What is the output of the code?

class HelloWorld {

    public static void main(String[] args) {

       int arr[] = { 30, 20, 10  };

       int temp = Arrays.stream(arr)

                                .average();

                                .getDouble();

        System.out.println(temp);

    }

}

What is the output of the code,

class HelloWorld {
