Edge Cases and Types in Java Programming
Understanding edge cases and types in Java programming is crucial for handling different scenarios with data types like numbers and strings. By identifying and handling these edge cases effectively, programmers can write more robust and reliable code. This knowledge is essential for navigating common pitfalls and ensuring the correctness of code implementations.

Announcements and Reminders Quiz 1 is tomorrow! many resources available! practice quiz, starred section problems, PracticeIt, and last-minute IPL help if you re sick please email us before your quiz date today: some more quiz tips :) R3 due tomorrow (eligible: P0, C1, P1, C2) R4 opens tomorrow (eligible: C1, P1, C2, P2) P2 is out, due next Tuesday, November 12th Thanks for your feedback last week! Matt will debrief on Friday. Lesson 12 - Autumn 2024
Quiz Tips: Overall Prepare for the open-book quiz! consolidate your notes! bookmark helpful practice problems, Ed lessons, and slides before the quiz, clean up your desktop & open relevant tabs reminder: no communication, generative AI work must be yours Budget time during the quiz (45 minutes) spend more time on what was tough during quiz 0 leave time to make a submission for each section Lesson 12 - Autumn 2024
Quiz Tips: Debugging & Programming Hit run, and hit run often Problems are primarily autograded, so make sure your code compiles and runs! Look at the output carefully Grading rubrics are in the spec read and think strategically! pay special attention to the S criteria, especially if low on time Testing you on reading the spec (+ debugging, programming) Think about edge cases Lesson 12 - Autumn 2024
Edge Cases and Types In languages like Java, it s helpful to think of common edge cases related to the type of the value. For example, for numbers (e.g. int, double) can you handle 0? division is especially nasty! for Strings, can you handle the empty string "" charAt is especially nasty! In future programming, you ll learn about many more of these (e.g. biggest and smallest numbers, null, empty array). Lesson 12 - Autumn 2024
