2. Consider the following two classes.

public class Bird {

public void act() { System.out.print("fly ");

makeNoise(); }

public void makeNoise() {

System.out.print("tweet "); }

}

public class Pigeon extends Bird { public void act() { super.act(); System.out.print("waddle ");

}

public void makeNoise() { super.makeNoise();

System.out.print("coo "); }

}

Suppose the following declaration appears in a client class:

Bird dove = new Pigeon();

What is printed as a result of the call dove.act()?
