Ed. The best way to ask a short question about the course materials is via Ed, an online forum in which students ask (and answer) questions. Please do not email such questions to individual staff members; use Ed. The course staff monitors this forum regularly.
Office hours. For more substantial questions about the course materials and assignments, you should attend office hours.
Books. Here are some good books about security, in case you are interested.
Java. Assignments that use Java were designed in Java SE Development Kit 11 - also known as JDK 11. Students who have completed COS126/226 will have JDK 11. We do not anticipate any compatibility issues if you have other versions of Java like JDK 8. If you run into issues with the autograders or Java versions, please contact course staff. To determine which version of Java is installed on your platform:
"version 11.0.11"(or similar).
See the Oracle website for download/installation instructions for your platformIf you need assistance installing JDK 11, see the undergraduate lab TAs in Lewis 121.
