CS 113 Introduction to Computer Science I Base Syllabus January 2012 Faculty Coordinator Dr Narain Gehani Junilda Spirollari Overview This course is a comprehensive introduction to the Java programming language teaching writing testing and debugging of programs The course has three major parts The first part teaches fundamental programming techniques that use primitive data types variables assignments expressions and operators control statements arrays and files I O The second part covers testing and debugging and teaches students how to write programs that work reliably The third part introduces object oriented programming The course guides students to the development of comprehensive Java applications Prerequisites CS100 Roadmap to Computing or equivalent Objective The objective of this course is to teach students how to write test and debug Java programs so as to produce reliable applications that meet specified problem requirements Material that Must Be Covered During the Semester Introduction to programming and Java programming language Data and Expressions Using Classes and Methods Decisions and Loops Arrays and File I O Objects Oriented Programming a Object Oriented Design b Defining Classes and creating Objects c Defining methods d Inheritance Testing and Debugging Exceptions Common Hour Exams This course has two common hour exams All sections take the same exam at the same time Students must attend these which are during common hour periods when no class is being taught Suggested Textbook s Introduction to Java Programming 8 E 2011 by Y

and Debugging Intro to correctness and robustness Writing correct programs Testing Introduction to debugger concept Run time and logical errors Step Commands Step Over Step Into and Step Return Breakpoint and resume command Other Eclipse debugging commands Inheritance Supplementary material as provided by instructor Ch 11 Deriving new classes from existing ones Superclasses and Subclasses Using the super keyword Protected modifier Creating class hierarchies Overriding Methods The Object Class Indirect visibility of inherited members 14 Exception Handling Exception Handling overview When to use exceptions Exception types Try catch statement The finally clause Ch 13 Exception classes I O exceptions Typical Assignments Lab and Homework Lab Assignments to be done in class 1 Health application BMI Body Mass Index is a measure of health on weight It can be calculated by taking your weight in kilograms and dividing by the square of your height in meters Write a program that given a weight in pounds and height in inches will display the BMI Note that one pound is 0 45359237 kilograms and one inch is 0 0254 meters 2 Game scissor rock paper Write a program that plays the popular scissor rock paper game A scissor can cut a paper a rock can knock a scissor and a paper can wrap a rock The program randomly generates a number 0 1 or 2 representing a scissor rock and paper and prompts the user to enter number 0 1 or 2 and displays a message indicating whether the user of the computer wins looses or draws 3 Reading from files Write a program that asks the user to read from the keyboard the name of a file containing exam scores The program reads exam scores from the file and displays on the screen their total and average Scores are separated by blanks Homework Assignments 1 Finding the factors of an integer Write a program that asks the user to read in from the keyboard an integer The program displays all its smallest factors in increasing order For example if the input integer is 120 the output should be as follows 2 2 2 3 5 2 Defining a class the Stock class As defined in Wikipedia the capital stock or just stock of a business entity represents the original capital paid into or invested in the business by its founders Design a class named Stock that contains a A string data field named symbol for the stock s symbol b A string data field named name for the stock s name c A double data field named previousClosingPrice that stores the stock price for the previous day d A double data field named currentPrice that stores the stock price for the current time e A constructor that creates a stock with specified symbol and name f A method named getChangePercent that returns the percentage changed from previousClosingPrice to currentPrice Draw the UML diagram for the class Implement the class Write a test program that creates a Stock object with the stock symbol JAVA and the previous closing price of 4 5 Set a new current price to 4 35 and display the price change percentage
