Can we remove new keyword from this program

I have following code.

class A
    {
        public void PrintA() {
            Console.WriteLine("PrintA() executed");
        }
    }

    class B {
        public void PrintB() {
            A a = new A();
            a.PrintA();
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            B b = new B();
            b.PrintB();
        }
    }

This code works for me. Can we do it a better manner like can we implement design pattern into it because this program has many new keyword. So can we remove new keyword.
