3 minute paper
- what is the concatention operator in java and what does it do?
- if a variable is declared within a method is it a local or an instance variable?
- Explain the difference between the lifetime of a local and an instance variable.
Elevator - Add Passengers - board Passengers - How to create an Array
- go over array and hand outs
Alice must do tutorials
- from tutorial if finished 145 can move to 150 - methods with parameters
The locations of variables
In Alice, variables can exist in at least two different locations in a program:

* Inside a method or function. (local variable)
* Inside an object but outside of a method or function. (instance variable or property)

One of the primary differences between the two different locations has to do with the lifetime of the variable.
The lifetime of object variables (properties)
In Alice, variables that belong to objects are called properties. They come into existence when the object is created, and they cease to exist when the object ceases to exist. As a practical matter, objects cannot be created or destroyed in Alice while a program is running, so properties belonging to an object exist during the entire running time of the program.

Just like local variables, every property is identified as belonging to a specific type.

By Dec 18th ALL Chapter 3 programming problems MUST be completed
