CS101 Exam #3 Topics

The final exam on Monday 12/10 at 7:00 PM is open book and open notes.  In fact, you can bring any book or other material that you like.  However, this doesn't mean that you don't need to study, because having a textbook won't write a program for you, only help you with syntax or definitions.  The best way to study for the test is to understand your homework questions.  The entire test is primarily on Java programming, where you will be asked to write a program or given a program and asked to describe it or give output.

Program Development and General Concepts

• The process of creating a program:  design, pseudocode, implementation, testing, maintenance
• Interpreted vs. Compiled programming languages
• Why Java is both interpreted and compiled, disadvantages

Java Fundamentals

• Data Types, differences of the primitive data types
• Structure of a program
• Method, variables, class, object, data member, identifier, statement, parameters
• Printing output, escape characters
• Precedence among mathematical operators
• Know how to use %
• Integer vs. Float and conversion of types
• Issues when converting (e.g. truncation)

Graphics

• Graphics coordinate system
• How to create colors
• Drawing rectangles, ovals, lines

Conditions, If-Statements, Loops

• Relational operators:  !=, ==, <=, >=, <, >
• Boolean operators:  &&, ||, !
• Combining boolean and relational operators :  e.g.  (x<3) && (y>4) || (!z)
• Precedence among operators
• If-statement
• Loops, be able to convert between the different types of loops
• While
• Do-While
• For

Classes and Methods

• Concept of creating instances of an object
• Format for defining a class including methods and data members
• Role of public vs. private
• How to define a method
• static methods
• Passing parameters to a method
• Primitive data types:  copied
• Objects: reference to actual object
• Constructors
