what design pattern can I use to create an object that implements a specific interface or multiple or any combination among the available interfaces? for Example say I have the following

interface A {
   void foo();
}

interface B {
   void bar();
}

interface C {
   void car();
}

class Agent {

}

I want to be able to say give me object of class Agent that implements interface A?

or

I want to be able to say give me object of class Agent that implements interfaces B?

or

I want to be able to say give me object of class Agent that implements interfaces C?

or

I want to be able to say give me object of class Agent that implements interfaces A,B?

or

I want to be able to say give me object of class Agent that implements interfaces B,C?

or

I want to be able to say give me object of class Agent that implements interfaces A,C?

or

I want to be able to say give me object of class Agent that implements interfaces A,B,C?

or

In general what I am looking for is to create an object which can have the functionality from any combination of interfaces.
