A rigorous treatment of objectoriented concepts using Java as an example language. • Development of sound programming and design skills, problem solving and modeling of real world problems from science, engineering, and economics using the object-oriented paradigm. Prerequisites • COMS W1004 or AP Computer Science with a grade of 4 or 5 • You should be familiar with basic Java concepts and programming principles • You should be able to write a 150-line program with 4-5 classes Course homepage http://www.cs.columbia.edu/~cmurphy/1007 • Please check the course homepage frequently for important announcements and changes to the reading assignments CourseWorks http://courseworks.columbia.edu/ • Check the “Discussion” section for questions related to the homeworks • Check the “Gradebook” to make sure our records match your own Grading • Homeworks: 60% • Final exam: 40% • These are “guidelines” for the final grade Homeworks • There will be five homework assignments this semester – You generally have one week to complete them • Homeworks will be posted on the course homepage and in CourseWorks Exams • An in-class final exam will be held on the last day of class: Wednesday, August 9 • Exam covers material from readings and lectures (so come to class!)
