Sorts of Questions:

- Draw a class diagram

- Given some code, predict the output (about 1/3 of the test)

- Given some code and a problem description, fill in the missing parts (about 1/3 of the test)

- Define simple terms (such as events, exceptions, files, streams, open, close, read, write, abstraction, encapsulation, uses, extends, inheritance, composition, reuse, overloading, overriding, polymorphism, signature, etc.)

- Explain a concept

- Compare and contrast two ideas

- If given code with graphical widgets, be able to predict what the screen will look like

- If given code with file input and output, be able to predict the contents of files and/or the output from the program

- Be able to write try/catch blocks

-
