The Structure of the Exam

• For all topics, you should be able to trace, analyze, and write Java code.
  • Questions will for the most part consist of:
    • presenting you with a piece of code and asking you what is output — or what the value of one or more variables are — once the code is executed
    • presenting you with a problem decription and asking you to write the corresponding code
    • asking you what is wrong with a piece of code and/or asking you to repair it
    • presenting you with a piece of code and asking you to trace the value of one or more variables as the code is executed
  • There may also be some multiple-choice and short answer questions.
• Although you will not be asked for definitions of terms, you should know them as they will be used in the text of the questions.
• At least 50 points on the exam will come directly from assigned exercises.
• You are only responsible for topics and material in the lecture notes and the CodeLab exercises / labs. The latter are a great way for you to prepare yourself for the exam.

The exam covers Lectures 1-3. Here is a detailed breakdown of the topics
