1. Look at the following code, which is the first line of a class definition: public class Tiger extends Felis In what order will the class constructors execute?

2. Write the declaration for class B . The class's members should be as follows:

m, an integer. This variable should not be accessible to code outside the class or to any class that extends class B.
n, an integer. This variable should be accessible only to classes that extend class B or are in the same package as class B.
setM, getM, setN, and getN. These are the mutator and accessor methods for the member variables m and n . These methods should be accessible to code outside the class.

calc . This is a public abstract method.

Next, write the declaration for class D , which extends class B. The class's members should be as follows:

q, a double. This variable should not be accessible to code outside the class.

r, a double. This variable should be accessible to any class that extends class D or is in the same package.

setQ, getQ, setR, and getR. These are the mutator and accessor methods for the member variables q and r. These methods should be accessible to code outside the class.

calc, a public method that overrides the superclass's abstract calc method. This method should return the value of q times r.

3. A superclass has the following abstract method:

public abstract int getValue();

Write an example of a getValue method that can appear in a subclass.

 

4. Write an interface named Nameable that specifies the following methods:

public void setName(String n)

public String getName()
