CST141: Principles of Computing Using Java



Introduces concepts needed to lay solid foundation for understanding object-oriented software development via problem specification, analysis, design, implementation and testing. Topics include methods, decisions, looping, arrays, code reusability, top-down design and UML. With extensive laboratory exercises, course educates and trains students to develop programs that are easy to understand and maintain.

Prerequisite: MAT111 or equivalent, and CST112 or equivalent, or permission of Chair/Academic Dean  •  Credits: 4 credit hours





At the end of this course, students will be able to:

  1. Define and use various programming concepts such as problem solving, top-down design, and structure charts
  2. Define and use the following Java concepts:
    1. Constant, type and variable declarations
    2. Built-in and user-defined methods with parameters
    3. Arithmetic and Boolean expressions
    4. Assignment, selection, and repetition statements
    5. One and two dimensional arrays
    6. Objects and classes including inheritance, polymorphism, abstract classes and interfaces
    7. Strings
    8. GUI (graphical user interfaces) basics and event driven programming
    9. Exception handling
    10. Text and binary I/O
    11. Recursion


  1. Class lectures and discussions.
  2. Use of audio-visual devices.
  3. Homework review and practice problems from textbook and other sources.
  4. Application problems on IBM compatible computers.


Do not expect to get an “A” grade for doing the base project; rather that grade is reserved for students who go beyond the requirements of the assignment.  Final grade will not be more than ten (10) percentage points higher than the examination average.

Multiple-choice unit quizzes based upon the assigned textbook readings will be given for most chapters.  Quizzes located in Blackboard consist of ten questions each and will be “open book.”  All quizzes must be completed by the due date listed in the course outline before 9:30 a.m. when class begins that day.


Students must submit all projects via Blackboard, an Internet website maintained by Suffolk County Community College and the State University of New York.  Click on any of the following links to watch videos that demonstrate how to use Blackboard in this course.

NO MAKE-UP EXAMS will be given unless the instructor so decides.  However, no student will be allowed to make up an examination that has been returned and discussed in class.  All assignments and projects are due by the end of the day (11:59 p.m.) on the date announced unless otherwise stated.  No late assignments will be accepted unless an extension date is prearranged with the instructor.

Although computer lab time may be scheduled each week during class time, students should be aware that additional lab time outside of class may be necessary to complete the requirements of this course. 


"The College expects that each student will exercise personal responsibility with regard to class attendance. All students are expected to attend every class session of each course for which they are registered. Students are responsible for all that transpires in class whether or not they are in attendance. The College defines excessive absence or lateness as more than the equivalent of one week of class meetings during the semester. Excessive absence or lateness may lead to failure in a course or removal from the class roster." (College Catalog and Student Handbook)

Attendance is not a factor in the computation of the course grade but may be a factor in determining class participation. It is the student's responsibility to make his/her attendance known to the instructor if arriving late. Students who stop attending classes without officially withdrawing from the course will receive a failing grade (FN).
