Material that might be covered on the exam:

• Syntax and basics of Java:
  • Some short answer syntax questions can be found at Practice Problem Set 1. (However, the exam will not have multiple choice questions.)
  • Java operators and their precedence.
  • You should know the basics of programming: how to accumulate sums, find the average of numbers, find the maximum or minimum of numbers.
  • Tracing of if-else can be found in Practice Problem Set 2.
  • Loops in Java: while, for, and do-while. Material about loops is referred to in the weekly lecture notes. See Week 5 Lecture for an extended loop example and other materials.

• Material about object-oriented programming:
  • Terminology:
    • Class - a blueprint for an object. (A class definition reserves no memory; rather it says how objects of a certain kind should be created and what they can do.)
    • Instantiate - create a object from the blueprint (using new).
    • Constructor - specifies how the object should be set up when it is created. (The constructor has the same name as the class name.)
    • Variable - name for a memory location that holds a particular type of object or value.
    • Method - group of programming statements that is given a name. (Methods define the actions that an object can take.)
    • Accessor method - a type of method that gets information about an object, but does not change its state.
    • Modifier method - a type of method that changes the internal state of an object in some way.
    • Field - contains internal state information of an object.
    • Client code - code that creates an object and/or asks it to do something.

  • Complete partially written class definitions.
    • Some practice problems can be found at Practice Problem Set 3

  • Write statements to instantiate objects and call methods of an class to solve a problem.

  • Material from specific classes studied in the course. Some of these involve specific Java library classes or classes from the text or from lectures that we have studied. (Special Note: You are not expected to memorize the names of the various methods or classes we have studied. The concepts are the important part.)
    • The Math class.
    • The Random class.
    • The String class.
    • The Rectangle class (from lectures).
    • The Circle class (from lectures).
    • The Counter class (from lectures).
    • The Primes class, that will print successive Fibonacci numbers and their factorizations (from lectures).
    • The ThreeHalves class, that will print the 3/2 sequence. See Week 3 Lecture.
    • The Dice class (from the lab).
    • The Coin class (from the text, page 179).
    • The Rational class (from the text, page 196).
    • The TimesTable class (from lectures).
    • The Time, Date, and DateTimeclasses (from lectures).
    • Various materials related to base conversions, and conversions between ints and Strings: See Week 4 Lecture.
    • The ConvertBase class, illustrating static and non-static methods (from lectures).
    • Testing println (from lectures).
    • The GetNext class (from lectures).
    • The Lines class, an applet (from lectures).
    • A test of logical operators, including especially de Morgan's Laws: LogicTable class, which prints a table of logical values (from lectures).

  • Determine appropriate fields or methods for a class definition from a word problem.
