Introduction to Object-Oriented Programming (OOP)
- Terminology - Be able to define:
  - Object
  - Class
  - Differentiate between object and class
  - Identity
  - State
  - Behavior
  - Variables (instance variable vs. class variable)
  - Constant
  - Method (instance method vs. class method)
  - Instance
  - Invoking, Invocation
- Benefits of Object-Oriented Programming (Know what these things mean)
  - Reuse
  - Class Hierarchy (Superclass, subclass)
- How is invoking a method on an object similar to sending a message among people?
- What do the public and private access levels mean?
Basic Java
- Terminology
  - Syntax
  - Semantics
  - Identifier (Java rules/our Java Coding Standard for identifiers)
  - Unicode
  - Literals
  - Type Casting
  - Assignment
  - Instantiation (and the role of "new")
- Java Comments
  - // (Single line)
  - /* */ (Multiple line)
  - /** */ (Javadoc)
- Primitive Types
  - What are the primitive types in Java?
  - How do they differ from reference types (objects) with respect to declaration and memory allocation?
  - Be able to draw memory diagrams for primitive types and objects (upon declaration, assignment, instantiation)
  - How are literals represented for float's, long's, etc.?
- Constants
  - What is the modifier that means an identifier is a constant in Java?
  - Be able to write java code to declare a constant.
  - What does our Java Coding Standard dictate about identifiers for constants?
- Variables
  - How are variables declared in Java?
  - What does our Java Coding Standard dictate about identifiers for variables?
  - Why do we need to instantiate reference variables (objects)?
  - How do we instantiate reference variables (objects) in Java?
- Expressions
  - What four things affect how expressions are evaluated/stored in assignment statements?
    - Operator Precedence - know the precedence among casting, parentheses, arithmetic (* / % + -), assignment (=)
    - Numberic Promotion -
      - How are mixed-mode expressions evaluated in Java?
      - Why is Java automatically able to promote a byte value to short, int, or long, etc.?
    - Assignment Conversion - Why is Java automatically able to promote a byte value to short, int, or long, etc. for assignment?
    - Casting Conversion - Why is casting necessary to assign a double value to an int, etc.?
  - Be able to evaluate expressions keeping these four things in mind?
- Assignment
  - What must be on the left hand side of an assignment statement?
  - Be able to tell whether or not an assignment statement is legal in java and be able to tell why not, if it isn't!
- Java Program Structure
  - We are writing applications using Java. What does an application in Java look like?
  - What is the syntax of the class declaration in a Java?
  - What is the syntax of the main class method declaration statement in a Java application?
  - What is the main class method used for in a Java application? What does it represent?
- Invoking Methods
  - What is the Java syntax for invoking a method?
  - What does the dot (.) mean?
  - Where can you find out what information an object's method needs to do its work in Java, i.e., where can you find out which arguments you must provide?
