Exam1:

When: Thursday, February 23rd 5:00-7:00pm

Where:

Note that several building entrances are locked between 5-6pm, and that you may need to find an alternate entrance when arriving late to an exam.  We recommend that all students plan to arrive 15 minutes early to avoid unnecessary hassle and stress.

  • Objects and Classes
    (instantiable) class vs. object (aka instance), class diagram, object diagram, constructors, creating objects using new, defining instance methods and declaring instance fields, default values for instance fields, interface vs. implementation, public vs. private, accessors and mutators, boolean methods, overloading, main (or driver or tester) class, object references and null, shared references (aka aliases), passing/returning references, calling instance methods, toString() method, instance constants, class (static) constants, class (static) variables, class (static) vs instance (non static) methods, arrays of objects, partially filled arrays of objects and null, initiallizing the array vs. the objects in the array, this reference;
