How is Java both "compiled" and "interpreted"?


----------------------------------------------------------------------

What is the static type of freakshow?  The dynamic type?

  Object freakshow = new Integer();


What is wrong with the following, given Integer defines a method
intValue() with return type int?

  int n = freakshow.intValue();


----------------------------------------------------------------------

Most methods you use in Java are instance methods.  Give an
example of a situation in which static/class methods must be
used.


In what ways are constructors similar to instance methods?  In what
way are they similar to static/class methods?


----------------------------------------------------------------------

What are the advantages and disadvantages of an interpreter
vs. compiler?


----------------------------------------------------------------------

Which one of these happens ONLY in derived classes?

  overloading
  overriding
  neither
  both


True or False:  Both overloading and overriding require methods to
have the same return type.


Which of these is a form of polymorphism?

  overloading
  overriding
  neither
  both

In Java, is there a way to store primitive type values in heap memory?


In Java, is there a way to store object instances in stack memory?


----------------------------------------------------------------------

Suppose both Ball and subclass ColorBall define instance method
bounce() and static/class method getClassName().  What methods are
called by the code below and which calls are dynamically dispatched? 

  Ball ballA = new Ball();
  Ball ballB = new ColorBall();
  
  ballA.bounce();
  ballB.bounce();
  
  ballA.getClassName();
  ballB.getClassName();


Is it possible to catch dynamic type errors at compile time?  


Is Java a statically typed language?


----------------------------------------------------------------------

How does the compiler determine whether a method call will be
dispatched dynamically?  


When would one want to use dynamic dispatching and when would one
want to use static dispatching?


----------------------------------------------------------------------

pass by value vs. pass by reference

Which model does Java use to pass variable values to methods?


Which model does Miranda use to pass variable values to functions?

(AB:  Bill, Hamed, Ryan)

Does a private method in a base class get inherited by the derived
class?


How about a protected method?


In Java, what is the difference between public, protected, private and
package visibility?


----------------------------------------------------------------------

Write code showing one example each of overriding a function and
overloading a function.

----------------------------------------------------------------------

Primitive type values are passed by __________, while class type
values are passed by __________.


----------------------------------------------------------------------

When calling an instance method, the Java virtual machine uses
__________ dispatching.


Java uses static dispatching when calling this kind of method.  What
is it?

(AB:  Tessa and Adrienne)

How do you call a static/class method?

  A.  Ball b = new Ball();
      b.classMethod(); 

  B.  Ball.classMethod();

  C.  classMethod();


----------------------------------------------------------------------

Ball b = new Ball();
Ball c = b;

How many Ball instances are allocated by the lines above?
